Specification of


RKI offers unique proprietary sensor technologies for hydrogen specific detection in either the % LEL or PPM ranges. By utilizing a proprietary molecular sieve coating that is built into both our catalytic or solid state sensors, false alarms from typical hydrocarbon interfering gases are essentially eliminated. For the LEL range, a special catalytic sensor is coated with a molecular sieve that eliminates the response to common background gases like IPA, methane, gasoline, etc. while providing a detection range of 0 — 100% LEL for hydrogen. The hydrogen PPM sensor can reliably detect leaks 20 times smaller than a standard catalytic sensor. This solid state sensor has a molecular sieve coating on the sensing element, which filters out interference from other gases and provides a 0 — 2,000 PPM range. Both the LEL and PPM range sensors are available with 24 VDC transmitters with linear 4-20 mA outputs.
