TES Electrical Electronic Corp. 1370 NDIR CO2 Analyzer electrician tool

NDIR CO2 analyser with temperature and humidity

The TES 1370 uses non-dispersive infrared technology to measure carbon dioxide concentration while simultaneously logging temperature and humidity. It is a handheld test instrument designed for indoor air quality assessments in commercial and residential buildings. The unit ships new in a single retail box.

Suited for HVAC technicians and facility managers

This meter suits professionals who need a combined CO2, temperature and humidity readout for ventilation verification. It is not for users who require data logging with time-stamped records or wireless connectivity to building management systems. Buyers needing a fixed wall-mount transmitter should consider a different instrument type.

NDIR sensing method for carbon dioxide

The analyser relies on an NDIR sensor to detect CO2 levels, a principle that distinguishes it from electrochemical or semiconductor alternatives. This method provides stable long-term drift performance for indoor monitoring applications. The specification defines the core measurement technology that determines suitability for the intended environment.
