Compatibility

Confirm the target gas (carbon dioxide (R744)), detection range (0–50000 ppm) and supply voltage (16–28 V AC (50/60 Hz)) 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.
