Telaire T6703 — consumer-grade CO₂ module, distinct from T6713: OEM specifications and integration

The manufacturer publishes model- and range-specific measurement data; numerical test values, measurement accuracy and digital output envelope are not interchangeable.

SpecificationOfficial product dataEngineering consequence
Sensor principleGold-plated optics NDIR CO₂ with ABC LogicMiniature optical gas sensor, not SGP-style VOC equivalent CO₂.
Measurement range0–5,000 ppm familyDo not assume all analog module versions use identical calibrated full-scale.
Accuracy at 400–5,000 ppm±75 ppm OR 10% of reading, whichever is greaterAccuracy grade is significantly looser than T6713 ±(30 ppm +3%).
Data / responseNew reading every 5 s; T90 below 3 minDigital sampling interval is not response-time guarantee.
Initial readinessOperational in <2 min; highest accuracy after about 10 minStartup state should be visible to BAS host during initial powering.
Environmental−10…+60 °C, 0–95% RH noncondensingHumidity condensation disrupts diffusion and optics.
Lifetime / stabilityMaker cites typical 15-year sensor life, <2%FS lifetime stabilityThis is a product design statement conditional on service and calibration environment.
Supply and footprintNominal regulated 5 V; 30 × 15.6 × 8.6 mmKeep OEM connector and supply filtering guidance.

Application, calibration and design details

T6703 is targeted at residential and consumer products where cost and general room ventilation matter; T6713 is a higher accuracy grade for demanding DCV. The accuracy formula uses the greater of ±75 ppm or ±10% of reading, not a sum. ABC Logic relies on recurring outdoor-like CO₂ exposure; avoid unqualified calibration-free claims in always-occupied rooms. Align the 0–5,000 ppm output, relay/controller alarm unit scaling and module communication with the right T6703 order number. Do not confuse T6703 with a T6700 parent family brochure or T6713.
