5.4 Sensor Replacement
Sensor life in the RECON/B SERIES is typically: 2 years for Carbon Monoxide & Hydrogen Sulfide and 1year for Oxygen and
Combustible.
The sensor needs to be replaced when the R
ECON/B SERIES can no longer be calibrated or if the sensor becomes erratic.
Contact ENMET for sensor replacement information.
