The RKI Direct Connect Sensors series gas sensors are state of the art gas detection sensors available for LEL, H2 Specific LEL, LEL IR, Oxygen, H2S, CO, CO2, and a variety of toxic gases.
Can be used for remote detection by mounting them onto explosion proof junction boxes, or they can mount directly onto controllers and be used as a completely standalone system
The explosion proof models utilize a patented coating which serves double duty as also being water repellant
Sensors are designed to be use in both indoor and outdoor settings
Users can also purchase splash guards to protect the sensors from very wet conditions
The Direct Connect Sensors are available in 2 forms: explosion proof and non-explosion proof
The explosion proof sensors are available as catalytic sensors for LEL, and LEL H2 specific
For hydrogen sulfide and carbon monoxide, the sensors utilize electrochemical technology which provides incredibly specific accuracy and quick response
. Oxygen sensors work with galvanic technology, and infrared sensors for methane, hydrocarbons, and carbon dioxide
Non-explosion proof uses a galvanic sensor for oxygen; electrochemical sensors for hydrogen sulfide, carbon monoxide and other toxic gases; and infrared for carbon dioxide
The response times are under 30 seconds for all gases except hydrogen sulfide and carbon monoxide in the non-explosion versions (with a response time of 35 seconds) and non-explosion proof model sensor for toxic gases which has a 60 second response time
The life expectancy of all sensors are between 2 and 5 years.
