T6700 Series Miniature NDIR CO2 Sensors

The Telaire T6700 Series consists of miniature NDIR CO₂ Sensors that have the accuracy and reliability of many larger sensors. The new small size allows OEM’s to integrate into smaller enclosures and equipment and uses significantly less power than many other devices on the market. All units are factory calibrated to measure CO₂ concentration levels up to 5000ppm, while maintaining accuracy across the range.

Within the T6700 Series:

Telaire T6703 CO₂ Module is configured for applications where CO₂ levels are less critical but an assessment of indoor air quality is required, for example in residential applications. Our minimum order requirement reflects the high volumes of these applications.
Telaire T6713 CO₂ Module is ideal for applications where accurate CO₂ levels need to be measured and controlled for indoor air quality and energy saving applications, such as demand control ventilation.
Telaire T6723-8K5 CO₂ Alarm Module is designed for heater applications requiring high limit controls.
Telaire T6793 CO₂ Sensor Module is ideal for applications where CO₂ levels need to be measured and controlled for indoor air quality and energy saving applications, such as demand control ventilation.

Ideal for use where CO₂ levels need to be measured and controlled for indoor air quality and energy saving applications, such as demand control ventilation.

Tolerance based on span gas of ±2%, which adds to the uncertainty, tested at Standard Ambient Temperature and Pressure (SATP). Subjecting sensors to environments less than 400 ppm for more than 15 minutes may affect accuracy due to ABC Logic algorithm. Please call for detailed product specifications. Based on nominal 5VDC input voltage. For best performance, DC supply should be a regulated, low noise power source. The module may exhibit a tolerance addition of ±60ppm when first installed.
