ModuleSpecifications

Method

Non Dispersive Infrared (NDIR), gold plated optics,

diffusion sampling (with Telaire’s Patented ABC

Logic Self Calibrated Algorithm)

0 to 5000 ppm

Dimensions

1.18in X 0.787in X 0.34in

(30mm X 15.6mm X 8.6mm)

400-5000 ppm +/- 30 ppm ± 3% of reading

400-2000 ppm +/- 25 ppm ± 3% of reading

Temperature Dependence

5 ppm per °C or 0.5% of the reading per °C,

whichever is greater

Stability

< 2% of FS over life of sensor (15 years typical)

Pressure Dependence

0.13% of reading per mm Hg

Notes:

adds to the uncertainty, tested at Standard

Ambient Temperature and Pressure (SATP).

than 400 ppm for more than 15 minutes may

affect accuracy due to ABC Logic algorithm.

For best performance, DC supply should

be a regulated, low noise power source.
