Product Overview
The Telaire T6793 Series CO2 Sensor Module, designed by Amphenol Advanced Sensors, is an OEM-focused, high-performance solution for measuring and controlling CO2 concentrations in indoor air quality and energy-saving applications, such as demand control ventilation. Featuring Telaires patented ABC Logic self-calibration software, it offers an affordable and reliable gas sensing solution that eliminates the need for recalibration in most applications. Its compact design and flexible platform allow for simple integration with other microprocessor devices. All units are factory calibrated to measure CO2 levels up to 5000 ppm.

| ABC Logic Notes | Patented self-calibration technique. Full accuracy achieved when exposed to outside ambient conditions (400 ppm) within a 7-day period. Typically reaches operational accuracy after 24 hours of continuous operation. Maintains accuracy if exposed to 400ppm at least four times in 21 days (typical residential ambient air). |
| Initial Tolerance (Note 5) | May exhibit 70ppm when first installed, corrected by ABC Logic within weeks. |
