CO2 Calibration Guarantee

GE is serious about minimizing maintenance, so each single-channel sensor (T8100/T8300) comes with a lifetime calibration guarantee.

CO2 ABC Logic Self Calibration

T8100 and T8300 Single Channel Sensors employ the patented ABC (Automatic Background Calibration) Logic self-calibration system. ABC Logic virtually eliminates the need for manual calibration in applications where the indoor CO2 level drops to outside levels during unoccupied periods (e.g. during evening hours). ABC Logic is a special software routine in the sensor that remembers the background readings for 14 consecutive evenings, calculates if there is a sensor drift, and then corrects for it.
