The R-G02 is a Belimo field-replaceable sensor module for Carbon Monoxide (CO) detection over the 0-250 ppm range using Electrochemical sensing. Sensor modules are swapped at the monitor without replacing the entire unit — the standard path for annual recalibration cycles and end-of-life sensor replacement.
Direct replacement sensor module for: 22G02-5A, 22G02-5B, 22G02-5C, 22G0214-5A, 22G0214-5B, 22G0214-5C. The module installs into the monitor housing in the field; no return-to-factory service required.
Annual calibration replacement and end-of-life sensor swaps for installed 22G monitors. Keep a spare module on hand to minimize downtime during scheduled life-safety inspections.

Frequently Asked Questions
What is the R-G02?
A field-replaceable CO sensor module (0-250 ppm, Electrochemical) for Belimo 22G gas monitors. It lets you replace just the sensing element at the monitor rather than the whole unit.
Which monitors does it fit?
It is the replacement module for: 22G02-5A, 22G02-5B, 22G02-5C, 22G0214-5A, 22G0214-5B, 22G0214-5C.
How often should the sensor be replaced?
Sensor modules require annual recalibration per UL 2075 and Belimo specifications. When a module fails calibration verification or reaches end-of-life, swap it at the unit — no factory return needed.
