81-1198-20 RP-3R Pump with 20 ft Hose, 10 inch Probe, and Tapered Red Nozzle for GX-3R by RKI Instruments

The RP-3R are compact, battery operated, motorized sample drawing pumps which attach to either the GX-3R or the GX-3R Pro to change them from diffusion operation to sample drawing operation. The model RP-3R pumps and the GX-3R or GX-3R Pro gas monitor make a complete solution for confined space entry.

The RP-3R is housed in a rugged plastic case with a quick disconnect fitting for hose attachment. It is provided with a 4" tapered red rubber nozzle. A hose and probe are available as optional accessories. Hose lenghts of 10' to 100' are available. The probe is equipped with an internal dust filter and clear body for easy viewing. The RP-3R uses one AA battery and will operate for up to 10 hours in normal mode (higher flow mode) with an optional ECO mode (lower-flow mode) that can last up to 16 hours. The pump quickly and firmly snaps onto the GX-3R or GX-3R Pro gas monitor and is easily removed when sampling is complete. No tools are required.

A push button POWER switch is used to activate the RP-3R, and the POWER LED illuminates when the RP-3R is on. If a low flow condition occurs, the FLOW LED flashes and an audible alarm will sound. The POWER LED flashes if low battery occurs.

SST1-H2 SST1 Single Gas Detector, H2 0-1000ppm Serviceable (Hydrogen) by WatchGas

The SST1 Serviceable offers one of the most cost-effective solutions on the market. With its 3-year replaceable battery and solid polymer sensor technology, the SST1 offers a compact and modular design without compromising its ruggedness. The SST1 Serviceable can be configured to your needs with one simple tap of the NFC and paired with the WatchGas Application. Monitoring for Low, High STEL, and TWA the SST1 will indicate any immediate risks and long-term exposure to toxic gases. SST1 is the platform that will allow us to expand on up to 8 different gases, so this is the ideal solution for your application.

Applications

• Oil and gas upstream
• Oil and gas downstream
• Contractors
• Site maintenance
• Turn arounds and shutdowns
• Boiler rooms
• Steel plants
• Laboratories
• Shipping
• Power generation
• Mining

Features and Benefits

• Easy Setup: Near Field Communication (NFC) is built in as standard and allows for a wide range of solutions depending on your needs. Simply pair with the WatchGas SST App to manage your fleet - bump, calibrate, assign or download event logs.
• Sensor: Using the latest in Solid Polymer Sensor Technology, our different target gases offer stability andreliability over extreme temperatures and conditions. With its smaller form factor and the removal of traditional Electrolyte, it is setting a new standard in the single gas market.
• Display: With the largest LCD in its category, the SST1's display shows the Real Time Gas Reading, TWA and STEL alarms. This allows for the user to make quicker decisions in a gas alarm environment. Bumper screens on either side of the LCD provide anti scratch protection ensuring the clearest of readings.
• Rugged: Designed with the harshest environments in mind, the SST1 offers an Ingress Protection rating of 67-68. The casing is a double shot housing that gives extra robustness while not compromising on quality. The screen protectors located on either side of the display are to protect the LCD from scratching and is required due to its smaller sensor profile.
• Alert: As a safety device it is essential that the device clearly notifies users of the presence of gas. The SST1 has a 95dB alarm at 30 centimetres which is the industry standard and is required in loud industrial environments. High and Low alarms can be configured by the customer and automatically updated directly on the device or through the SST Dock.
• Serviceable: The SST1 real time monitor is a cost efficient solution for users with STEL, TWA and real time requirements. SST1 real time allows users to replace battery and sensors to maximize the lifetime of the unit. Press and hold the button for 10 seconds to reset TWA/STEL for worker shift change.

72035 SkyMaster Pro ED 20x80mm Porro Binoculars by Celestron

Celestron SkyMaster Pro ED binoculars are the ideal choice for amateur astronomers or anyone who observes at great distances. The SkyMaster Pro ED uses superior optics, coatings, internal parts, and housing materials. With large objective lenses, BaK-4 prisms, ED glass, and fully multi-coated optics utilizing Celestron's proprietary XLT coating technology, the view through a SkyMaster Pro ED sets the standard for astronomy binoculars.

ED Objective Lenses

Extra-Low Dispersion (ED) glass virtually eliminates chromatic aberration, also known as color fringing, a visual phenomenon common in magnified optical systems. SkyMaster Pro ED delivers edge-to-edge sharpness with excellent color correction and razor-sharp images.

Not all ED glass is created equal. Celestron's high-quality ED glass delivers brighter, sharper images than non-ED binoculars. The difference is especially apparent in low-light conditions.

Coatings and Prisms

All of Celestron SkyMaster Pro ED's lens surfaces are fully multi-coated and feature Celestron's proprietary XLT optical coating technology. These powerful coatings, similar to the ones you'll find on our observatory-grade telescopes, decrease reflectivity for higher optical throughput across a broad range of the visible light spectrum. What's more, the prisms inside the binocular are made of high-quality BaK-4 glass, further boosting light transmission. Working together, the fully multi-coated lenses and BaK-4 prisms deliver more light from your target to your eye for brighter, more detailed views.

Objective Lenses

The 80mm objective lenses offer plenty of light-gathering ability for superior low-light performance. The objective diameter-to-magnification ratio is ideal for scanning the skies, observing the Moon and planets, and exploring all the best deep-sky objects. Celestron SkyMaster Pro ED also makes an excellent choice for long-distance land-based viewing–especially at dawn or dusk.

The Body

Custom-designed rubber armor and a durable chassis protect your SkyMaster Pro ED binocular from damage without weighing you down. Viewing through SkyMaster Pro ED binoculars is comfortable for eyeglass and non-eyeglass wearers alike, thanks to the retractable eyecups and more than 15mm of eye relief. Eyeglass wearers can see the entire field of view while looking through the eyepiece with their glasses by twisting the eyecups down. For those who do not wear eyeglasses, the eyecups position the user's eye behind the eyepieces at the correct distance for optimal viewing.

Ways to Observe

The Celestron SkyMaster Pro ED binocular is tripod-adaptable. Use the built-in tripod adapter on the balance compensation rail to mount it on any standard photographic tripod or monopod for extended viewing or digiscoping (photography through the eyepiece).

SkyMaster Pro ED's eyepieces are threaded to accept standard 1.25" astronomical eyepiece filters. Adding the right filter can deliver game-changing views for terrestrial and celestial observing. For terrestrial observation, filters can reduce the brightness of sand, snow, and water. For nighttime viewing, filters can cut glare, minimize eye strain, increase contrast, and even combat the effects of light pollution. Remember, the binocular needs a set of two filters.

Share your greatest discoveries with friends and family! Pair your SkyMaster Pro ED binocular with a smartphone adapter to capture images and video through the eyepiece.
