The Telaire T3030 Series is a range of carbon dioxide (CO2) sensors built for measuring CO2 in harsh or difficult environments, supplied under part numbers including T3031-2-2K-24-P, T3031-2-5K-25-P, T3031-2-10K-24-P, T3032-2-5K-24-P, T3032-2-10K-24-P and T3032-2-20K-24-P. Reliable CO2 measurement in demanding settings supports HVAC control and ventilation decisions where standard sensors would be damaged or drift out of tolerance, protecting both air quality and energy use.

Measurement uses Non-Dispersive Infrared (NDIR) technology in single or dual wavelength form. Single-wavelength accuracy is plus or minus 30 ppm or 3% of reading between 400 and 1250 ppm, and plus or minus 5% of reading plus 30 ppm between 1250 and 2000 ppm. Dual-wavelength builds cover up to 20% CO2 concentration, with accuracy of plus or minus 5% of reading or plus or minus 0.3 vol% CO2 from 0 to 25 degrees C. Resolution is a minimum of 10-bit or analog equivalent. Sensors are shipped factory calibrated and rated for accuracy across a 10-year life.

The modular casing combines range, supply voltage and output type to suit each application, mounts with two external tabs, can be rated up to IP67 depending on build and is available with potting. Analog outputs of 0 to 5 V, 0 to 10 V and 4 to 20 mA are offered alongside digital options. Typical uses include incubators, buses, refrigerators, subway stations, railway carriages and agricultural buildings such as glasshouses and livestock sheds.
