Carbon Dioxide ABC Logic™ Self Calibration The single wavelength 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. With ABC Logic enabled, the sensor will typically reach its operational accuracy after 25 hours of continuous operation at a condition that is exposed to ambient reference levels. Sensors will maintain accuracy specifications with ABC Logic enabled, given that it is at least three times in 14 days exposed to the reference value and this reference value is the lowest concentration to which the sensor is exposed. Note: Applies when used in typical indoor ambient air. Consult Telaire if other gases or corrosive agents are part of the application environment. CO2 Calibration Guarantee Telaire is serious about minimizing maintenance, so each single-wavelength sensor comes with a lifetime calibration guarantee. And each dual wavelength sensor has a two-year calibration guarantee.

Ordering Information

Please discuss your specific needs with the Telaire account management team, as many configurations are possible. Some combinations are already in production. Derivatives include lesser ingress protection, higher fire and smoke ratings, different outputs, and different calibration levels.
