65-2340RK-ASH3 S2 Series Arsine (AsH3) 0 - 1.5 ppm Sensor/Transmitter, Non Explosion Proof with J-Box 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.
