65-2320RK-C S2 Series Detector / Amp / Stainless Steel J-box, Oxygen, Partial Pressure Sensor, 0 - 25% volume, CO2 Resistant OS-C11 Sensor by RKI Instruments

Having a reliable gas sensor is detrimental to the safety and security of workers in potentially unstable work environments. In many cases, the decision to use a gas detection device with a reliable sensor can be the difference between life and death. RKI Instruments understands the reliability of gas sensors should be a top priority for workplace safety managers. Their team of experts works diligently to incorporate the most advanced technologies with the highest industry standards.

For nearly 20 years, RKI Instruments has worked in the gas detection industry. Its line of products leads the industry in innovation and technology. Every year, the company commits to achieving a higher level of productivity and delivering the best gas detection products on the market. With the introduction of their high performing, low cost S2 Sensor Transmitter, RKI is fulfilling that commitment.

S2 Sensor/Transmitter

The RKI S2 Sensors and Transmitters use state of the art sensor technology to detect common gas hazards. Their efficient design and cost effectiveness make them an industry choice for atmospheric monitoring. The sensor transmitters can be used in both indoor and outdoor conditions and are designed to interface with RKI controllers or PLC/DCS systems.

The sensors are available in explosion proof casing for monitoring LEL, H2 specific, oxygen, H2S, CO2, and carbon monoxide. These sensors also have flame arrestors and are approved for use in hazardous environments. The oxygen, H2S, CO, and CO2 sensors are available in non-explosion proof models. The sensors provide highly specific and quick detection and are long lasting. The sensors can be quickly replaced while on the field and do not require any tools.

Explosion proof S2 Sensor/Transmitter

The explosion proof sensors use a variety of detection mechanisms including catalytic for LEL and LEL- H2 specific; metal oxide semiconductor for hydrogen; galvanic cell technology for oxygen; electrochemical for hydrogen sulfide and carbon monoxide; and infrared for carbon dioxide, methane, and hydrocarbons. A hydrogen specific sensor transmitter is not available. Each of these detection methods come with their own measuring range specifications and response times varying from 20 seconds to 45 seconds. These sensors are stainless steel and are housed in a cast aluminum explosion proof J-Box (a stainless steel J-Box is also available).

Non-explosion proof S2 Sensor/Transmitter

The non-explosion proof sensors use galvanic cells for oxygen detection; electrochemical technology for hydrogen sulfide, carbon monoxide, and other toxics; and infrared technology for carbon dioxide detection. The response times vary between 20 seconds and 60 seconds depending on the targeted gas, and the measuring ranges vary as well. These sensors are plastic or aluminum and housed in an explosion proof J-Box.

Accessories

The S2 Sensor/Transmitter has numerous accessories available to meet the individual workplace's needs. Such accessories include calibration adaptors, flow through adaptors, remote horns and lights, calibration kits, battery backups, splash guards, air aspirator adaptors or panels, and data loggers.

Each sensor comes standard with a one year warranty for materials and workmanship.

94022 Aluminum Dew Shield with Cover Cap - 9.25" by Celestron

The Celestron Aluminum Dew Shield with Cover Cap is an essential accessory that protects your telescope tube in the field. The dew shield reduces radiative cooling of the Schmidt corrector lens to the night sky, thus keeping the lens below the dew point longer preventing dew formation on the lens. Additionally, the Aluminum Dew Shield increases image contrast by blocking stray light from entering the telescope for better viewing and astroimaging. Use the Aluminum Dew Shield on your 9.25" Schmidt Cassegrain and EdgeHD telescope tube confidently, knowing it was created for your exact instrument.

Construction

The Aluminum Dew Shield provides a perfect, custom fit for 9.25" Celestron telescope tubes. The exterior of the dew shield is a rigid, aluminum cylinder that will not fold, flex, or deform. Inside, a velvet-lined interior absorbs any additional stray light and excess moisture, creating optimal contrast when viewing and imaging. Attach the dew shield to your telescope tube with the two adjustable clips to ensure a snug fit.

We've also constructed the cover cap from durable yet lightweight aluminum. When your telescope is not in use, place the cover cap on your dew shield to protect your Schmidt corrector from stray dust particles. The cover cap also offers you the ability to quickly and easily acquire dark frames for imaging.

If you're an astroimager who enjoys using your Schmidt-Cassegrain or EdgeHD in the Fastar/Hyperstar configuration, you're probably used to running cables out the front of the dew shield. Simplify and streamline your setup with the Aluminum Dew Shield's integrated cable management slot at the base. This slot gives you an easy way to corral essential cables (like the ones for our Dew Heater rings) without potentially allowing light pollution to leak in. Also, there are cutouts to accommodate dovetail rails on the top and bottom of the telescope tube, ensuring a good fit regardless of the configuration.

Enhance your setup

When purchasing this item, you will receive 2x adhesive Celestron logo labels. Use them on your dew shield or anywhere else you like!

Check out the 9.25" Dew Heater ring and the Smart DewHeater and Power Controllers to optimize your setup for the ideal dew-free night of observing and imaging.

• Fits 9.25" Schmidt-Cassegrain and EdgeHD telescope tubes
• Helps prevent dew formation on the Schmidt corrector lens
• Prevents off-axis glare from entering the optical system
• Rigid body with a velvet-lined interior surface to reduce stray light
• Two adjustable clips for easy installation and disassembly
• Cable management at the base of the shield–perfect for using the Fastar/Hyperstar configuration or using in conjunction with the Celestron Dew Heater Rings
• An included cover cap keeps your telescope free from dust when not in use
