See the Universe in HD

EdgeHD is an aplanatic, flat field Schmidt-Cassegrain telescope that produces aberration-free images across a wide visual and photographic field of view. The optical system was designed to reduce more than just off-axis star coma; it also provides an astrograph-quality flat focal plane all the way to the edge of the field of view.

True Astrograph Quality

Many optical designs that advertise themselves as "astrographs" actually only produce pinpoint stars across a curved focal plane. While this may be acceptable for some visual observing, stars will appear out of focus at the edge when used with the flat chip sensor of a digital camera. EdgeHD optics produce a focal plane more than three-times flatter than a standard Schmidt-Cassegrain telescope and dramatically flatter than competing coma-free designs. This guarantees you visibly sharp stars across some of the largest CCD chips available today. Learn more about EdgeHD technology.

Improved Performance

Superior edge performance not only creates rounder, more pleasing stars, but actually improves the resolution and limiting magnitude when compared to telescopes of equal aperture. With Celestron's StarBright XLT optical coatings on every surface, EdgeHD optics gives you maximum light throughput across the widest visual and photographic spectrum.

Mechanical Features

In addition to EdgeHD's optimized optical design, the telescope tube has been redesigned to make sure you get the most from your optics each and every night.

• Mirror clutches - Flexible tension clutches hold the mirror in place and reduce image shift when taking long exposure astro-images. Once focused, the flexible rods allow the mirror to be held in place without putting any force or pressure on the mirror assembly, keeping the image centered in the eyepiece (or on the sensor).
• Tube vents - Cooling vents located on the rear cell allow hot air to be released from behind the primary mirror. Each vent has an integrated 95-micron micromesh filter guaranteed to let warm air out without letting dust in.
• Fastar versatility - EdgeHD is the most versatile imaging telescope available today. At its native f/10, you can achieve the image scale necessary to capture the smallest of deep sky objects. Add the optional reducer lens custom-designed for your size EdgeHD tube and you can increase your field of view without sacrificing optical performance. A Barlow gives you added power for high-resolution planetary, lunar and solar imaging. All EdgeHD optical tubes are Fastar-compatible, allowing the secondary mirror to be removed and replaced with a third party lens accessory for ultra-fast f/2 wide field imaging.

Individually Tested

Every EdgeHD that ships has been tested not only for the surface quality of each optical component, but also with a camera and artificial star to ensure the imaging system meets our rigid quality assurance. This final acceptance test confirms the EdgeHD will perform in the field and deliver high-quality astroimages.

G222E-0107 G222E Dual sensor configuration - Carbon monoxide (CO) (500 ppm) and 2-year Oxygen (O2) - Instrument Only by GfG

Sturdy and compact dual gas detector for monitoring toxic gases, H2 and O2

The G222E is the first device in GfG s Micro 5 series. At present, it is the smallest and at the same time one of the lightest one- to two-gas detectors with two electrochemical gas sensors (EC) in the world.

Safety through quality and functionality

Equipped with high-quality, precise and durable sensors, the system is individually tailored to your requirements. Currently, sensors are available for 20 different gases and a wide array of measuring ranges. Combine them according to your requirements or increase the safety of your employees even further by redundant use of the same sensors to minimize the danger from a specific gas.

A simple, two-button menu and a large, easy-to-read display provide easy menu navigation and reliable information even under difficult conditions.

Suitable for long periods of use

Depending on sensor equipment and configuration, the G222E has an average operating time of up to 9 months at 10 hours per working day or 90 days in 24/7 operation. The battery of the G222E can be changed in seconds if necessary and the gas detector is ready for use again.

Data logger

The internal data logger stores the last 2600 events. These include measured values, alarms, TWA and STEL values, and time as well as temperature information.

Calibration Cap & Smart Cap

Calibration and adjustment of the G222E are quite simple. All you need is the Calibration Cap for manual zero and test gas application.

If you want to read out the content of the data logger, you will need the Smart Cap, a USB connection cable and the Config Software for the G222 series instead.

0572 1753 175 T3 2-Channel Temperature Logger with External Thermocouple Connections (Type K,T) by Testo

The temperature must often be monitored and recorded in two places. With two interfaces for thermocouple probes (Type K and Type T), the testo 175 T3 is suited to this task. For example, in order to test the functionality of a heating system, the flow and return temperatures must be measured and documented. Refrigeration systems are tested in a similar way. In the autumn, the heating season begins, and with it the complaints from tenants that apartments cannot be heated to the desired extent. Using the testo 175 T3 and the versatile pipe clamp probes, you can take targeted measurements of the flow and return temperatures of individual radiators, in order to be able to identify and remedy causes (e.g. silting).

• Integrated USB and SD card interface for reading out data
• Large memory for 2 million measurement values - large, easily legible display
• Simultaneous monitoring and recording of two temperature measurement sites
• Easy monitoring and documentation, e.g. of flow and return temperature of a heating system
