8325865 X-am 8000 Multi-Gas Detector, Basic, Diffusion by Draeger

Clearance measurement was never this easy and convenient: The 1 to 7 gas detector detects toxic and flammable gases as well as vapors and oxygen all at once – either in pump or diffusion mode. Innovative signaling design and handy assistant functions ensure complete safety throughout the process.

Multi-gas detector

• 1- to 7 gas detection device
• for clearance measurement
• detection of toxic and combustible gases as well as vapors and oxygen

Specially designed for use with a pump, optimized for clearance measurement

The Draeger X-am® 8000 is equipped with a very powerful pump. It can be connected with hoses of up to 45 meters in length. A pump adapter makes it easy to switch between diffusion and pump mode at any time. This means the pump is only operated when you actually need it. That saves energy, reduces wear and tear, and extends the lifespan of the pump.

Handy and durable, the Draeger X-am® 8000 is intuitive to operate single-handedly using three function keys. The easy-to-read color display clearly lays out all the information for you.

The multi-gas detector also features advanced software functions including change of measurement gas for PID, CatEx and IR sensor during operation. This is based on an on-board library and a convenient assistant to hide unused sensor channels and adapt the flexible instrument to the measurement task.

Standard accessories include a sturdy shoulder strap so you can comfortably carry the X-am 8000. Thanks to its compact and robust construction, the device can withstand even the harshest conditions.

Clearance measurement, release and documentation in no time

The X-am 8000 effectively supports various applications with specially developed assistant functions that guide you through each process step by step. During clearance measurement, for example, the smart assistant calculates the necessary flooding time for the device and probe (FKM hose) based on parameters such as measuring gases, temperature limits, and the indicated hose length. Additionally, customer defined flooding times are also possible.

When monitoring for potentially high methane concentrations, an optional automatic measurement range switch makes it easier to take a reading: If the Cat-Ex sensor measures values above 100 % LEL, the display switches to the range of 0 to 100 vol %. A similar function to measure in % LEL and vol % simultaneously is also available for the IR EX ES sensor.

The DraegerSensor CatEx 125 PR Gas offers a special variant for the measuring gas methane, which enables measurements in the ppm range. The performance of selected sensors has been verified by an external approval body within the scope of the measurement performance approval (EN 60079-29-1) for combustible gases and vapors including methane, propane and n-nonane.

An additional useful tool is CSE Connect. It combines an app, specially designed for the X-am 8000, with a cloud-computing solution. Measuring jobs can be quickly and easily transferred to the app using an online application. An optional Bluetooth® module in the Draeger X-am 8000 enables measured values to be transferred automatically to the CSE Connect app. You can also easily and conveniently use the app to create measurement reports. This saves time and helps you manage your measuring tasks during clearance measurements more efficiently.

Clear signaling design

The signal system of the Draeger X-am 8000 is based on a clear color code, in accordance with the requirements of EN 60079-29-1, EN 45544-1 and EN 50104:

• Red light = gas alarm
• Yellow light = device-related alarm, e.g. low battery
• Green light = device is ready for use

The green glow of the D-Light allows you to see from a distance whether the device has been properly tested and is ready for use.

In case of an alarm, the X-am 8000 alerts you with colorful warning LEDs, a loud horn (100 dB(A) at a distance of 30 cm), and clearly palpable vibration. Optionally, four preset hazard symbols are available for the display which explicitly indicate the presence of explosive or toxic gas hazards, for example. This allows the user to easily recognize the type of hazard based purely on the symbol displayed.

The X-am 8000 is equipped with an impact detection system. The event report indicates whenever severe mechanical impacts have occurred that might result in functional impairments of the device or the sensors. These are also documented in the data logger. With this information, a device operator can specifically check the device. The instrument can also be locked after a detected impact as well.

Economical Fleet Management

Bumptest and calibration are carried out simply and quickly using the Draeger X-dock® calibrating station. Its low test gas consumption keeps operating costs to a minimum.

Its reporting function and numerous other useful features make the X-dock Manager PC software a smart addition to any fleet management operation. To identify devices in your fleet, you can either use tried and tested barcodes or an integrated RFID transponder.

Specialist for high and low hydrocarbon concentrations

To measure hard-to-detect hydrocarbons, you can fit the Draeger X-am 8000 with one of two high-performance PID sensors. The PID HC covers a measurement range of 0 to 2,000 ppm (isobutene). The PID LC ppb is particularly suited for a measurement range of 0 to 10 ppm (isobutene) with a high resolution in the range below 1 ppm.

For benzene-specific measurements, the X-am 8000 can be used with a pre-tube. The advantage: You only need one measuring device for this application, which significantly reduces the costs of purchasing, maintaining and transporting devices in use. The use of pre-tubes is supported by a built-in assistant.

Inductive charging protects against wear and tear

The X-am 8000 features inductive charging. This makes it easier to operate and increases the lifespan of the device. Issues like corrosion and contact problems in the charging cradle are a thing of the past. You can charge (outside of explosion-hazard zones) and measure at once, e.g, when using inside vehicles or on machinery.

The charging cradles can connect with one another, take up minimal space, and are compatible with existing Draeger X-am® series cradles.

91079 8" Rowe-Ackermann Schmidt Astrograph (RASA 8) Imaging Kit by Celestron

Armed with the RASA 8 Imaging Kit, you can create stunning, deep-sky astroimages in minutes and seconds–not hours or days!–even from a light-polluted backyard. Discover the fun and excitement of astroimaging the easy way with the acclaimed Rowe-Ackermann Schmidt Astrograph (RASA) telescope and two indispensable imaging filters: the Light Pollution Filter and Hα-Hβ-OIII Filter. Whether you're new to imaging or a seasoned pro, you'll enjoy unparalleled convenience and stunning results–even when photographing the most elusive deep-sky targets.

RASA: Imaging at f/2.0

At Celestron, we love astroimaging. But we're well aware of the challenges our favorite hobby can sometimes involve: trekking long distances to dark skies, precisely aligning and guiding an equatorial mount, and capturing hours of very long exposures to gather enough photons to see the spiral arms and faint details of our favorite celestial objects. In a quest to solve all those challenges, our engineers joined forces with storied optical designers Dave Rowe and Mark Ackermann to create RASA.

While a traditional SCT telescope places the imaging sensor at the Cassegrain focus at the rear of the telescope, RASA places the sensor at the prime focus at the front of the telescope. Instead of imaging at f/10 like you do with an 8" Schmidt-Cassegrain (SCT), RASA works at lightning speed, f/2—25 times faster! In 10 minutes with RASA, your image is as bright as it would be in 4+ hours with an SCT (albeit with a wider field of view).

When you image with a RASA 8, you can use much shorter exposure times. Add a sensitive camera and the proper "live stacking" software, and the 8" RASA can provide an almost real-time "observing" experience—even from the city. View images on a computer in seconds that are brighter and more detailed than you'd see through a much bigger telescope with the naked eye. Or capture and stack lots of short exposures and process the data; you'll be stunned at the details you can bring out.

What's more, RASA's speed lessens the tracking demands on your mount. You'll be using shorter sub-exposures so you won't need to track accurately over extended periods. In many cases, you won't even need to use an autoguider. And since RASA 8 weighs just 17 lb, it pairs perfectly with a wide variety of mounts, including the grab-and-go Advanced VX.

Although RASA has revolutionized the world of astroimaging, its influence goes far beyond astroimaging. Researchers and government agencies around the world have discovered that RASA is the ideal tool for detecting errant space junk and asteroids. Arrays of RASAs are deployed worldwide, scanning the skies and protecting our satellites in orbit.

Flat-field Performance Perfectly Paired with Today's Cameras

The 8" RASA delivers a flat field without optical aberrations for razor-sharp stars across a wide field of view. It can capture detailed deep-sky astronomical images at a fraction of the cost of other slower and smaller telescope designs, like refractors.

The RASA 8" has many of the same thoughtfully designed features as its "big brother" RASA 11, including the integrated air-cooling system, internal filter mount, and sturdy CGE dovetail mounting bar. Purely designed for imaging, the 8" RASA cannot be used visually. The focal plane is located at the front of the optical system, so it cannot accommodate a traditional eyepiece.

Unlike the 11" and 14" RASA, which both work with DSLR and large astronomical cameras, we designed the 8" model with color astronomical CMOS cameras, smaller CCD cameras, and mirrorless cameras in mind. (RASA 8 does not work with standard DSLR cameras.) It is optimized for sensors with up to a 22mm diagonal but performs well with sensors up to a 32mm diagonal. The APS-C sized sensors used in many mirrorless cameras are a good choice. Note that 42mm full-frame sensors can also work, but performance diminishes at the edges of the sensor, and field illumination is reduced. We don't recommend pairing RASA 8 with any camera body more than 4" in diameter. See the chart below to determine if your camera is compatible with RASA 8.

Ultra-Stable Focus System

With the launch of the 8" RASA, Celestron unveiled a new focuser design that mitigates lateral movement of the primary mirror when focusing, slewing, or tracking with the astrograph. Precise focusing is easier and more stable than ever. The key to the Ultra-Stable Focus System is a precision linear ball bearing, which we individually test during assembly to ensure optimal results.

Includes Two Must-have RASA 8" Imaging Filters

Along with the RASA 8" optical tube, this kit also includes the Hα-Hβ OIII Imaging Filter and the Light Pollution Imaging Filter. This kit maximizes your RASA 8" telescope's potential to capture stunning images under any sky conditions, ensuring precise targeting of specific celestial objects and optimal light transmission.

Light Pollution Imaging Filter - This broadband filter effectively blocks specific wavelengths of artificial light while allowing the desired wavelengths of light emitted by celestial objects to pass through. When you add this filter to your RASA, you'll see vibrant, detailed celestial objects that "pop" against a dark sky background with excellent overall contrast. This filter blocks light from some of the most common sources of artificial and natural light pollution between 400 and 700 nm (i.e., the visible spectrum), including high- and low-pressure sodium-vapor streetlights, mercury-vapor streetlights, and natural airglow caused by oxygen in the atmosphere.

Unlike some light pollution filters, Celestron's filter blocks only specific areas of the spectrum instead of wide regions. This helps to maintain image brightness and color balance. In addition, particular wavelengths associated with emission nebulae, such as H-α (656nm), H-β (486nm), OIII (496nm and 501nm), and SII (672nm), are highly transmitted, ensuring minimal loss of image brightness for those objects.

H-α H-β OIII (Hα-Hβ-OIII) Imaging Filter — The specialized Hα-Hβ-OIII Imaging Filter, also known as the Nebula Filter, is a narrowband filter that allows very high transmission of select wavelengths of light from emission nebulae while blocking the rest of the spectrum. You'll immediately notice much higher contrast in your images, even from your light-polluted backyard! And since the transmission at the critical wavelengths is so high, the nebulae are not dimmed—only the background is made blacker.

The H-α H-β OIII Imaging Filter is perfect for imaging emission nebulae like the North America Nebula (NGC 7000), Lagoon Nebula (M8), Orion Nebula (M42), and the Carina Nebula (NGC 3372). The transmission spectrum for the H-α-H-β OIII Imaging Filter is 85% or greater at key wavelengths (486nm, 496nm/501nm, 656nm) and less than 0.5% transmission elsewhere. And while other nebula filters can't keep up with RASA's fast optics and end up blocking some of the the wrong wavelengths, this filter is engineered to pair perfectly with this ultra-fast f/2 system.

Both the Light Pollution Filter and the H-α-H-β-OIII Imaging Filter are custom-engineered to work with RASA 8, so they won't block any of the "good" wavelengths, specifically targeting light pollution and other undesired wavelengths. The filters fit directly into the internal filter mount in RASA 8's front lens cell, where the optical window normally mounts. To use a filter, you first remove and replace the clear window with the desired filter. Since you are not introducing new layers of glass into the system when you swap out the window with the filter, you maintain RASA's exacting performance.

Each filter has a plastic storage case to safely store the filter or the optical window that came with your RASA when not in use. You will also receive a spectral transmission graph unique to each individual filter, verifying its performance.

• A Winning Astrophotography Kit – Combine the legendary 8" Rowe-Ackermann Schmidt Astrograph with two must-have filters – the Light Pollution Reduction Filter and the Hα-Hβ-OIII Filter – for a blazing-fast f/2.0 system that can produce stunning images of a wide array of astroimaging targets.
• Ultra-fast Rowe-Ackermann Schmidt f/2.0 Optics – Don't spend hours capturing your images – with RASA 8's f/2.0 optical system, you can gather the same image brightness 25 times faster than an f/10 system. And RASA 8 images aren't just bright and full of detail; they're also free from optical defects like field curvature, coma, astigmatism, and chromatic aberration.
• Patented Technology that Researchers Trust – Beyond imaging, RASA is the perfect tool for detecting errant space junk and asteroids. Scientists and government agencies use RASA arrays to monitor the space environment and protect our satellites.
• Built for Today's Cameras – Designed with color astronomical CMOS cameras, smaller CCD cameras, and mirrorless cameras in mind, RASA 8's flat field provides pinpoint stars and excellent performance across an entire APS-C sensor.
• Ultra-Stable Focus System – A precision linear ball bearing virtually eliminates image shift. RASA performs over a wider spectral range than most telescopes, from 400 nm to 800 nm, so more of the light passing through the astrograph is in sharp focus.
• Includes Two RASA Imaging Filters – When you purchase this kit, your RASA is ready to handle a variety of imaging targets and observing conditions right out of the box. The Light Pollution Reduction Filter and Hα-Hβ-OIII Filter enhance your images of faint targets like nebulae by blocking light pollution, improving image contrast, and darkening the sky background. Celestron engineers designed each filter to fit seamlessly into RASA 8's optical path.
