Compatibility

Confirm the target gas (hydrocarbon refrigerant (R290 propane / R1270 propene / R600a isobutane)), detection range (0–5000 ppm) and supply voltage (16–28 V DC) match the installation before ordering; the sensor element is gas-specific and factory-calibrated. This Heavy Duty version is ATEX/IECEx-certified for hazardous areas — do not substitute a standard version where a certified unit is specified.
