1. Product Introduce

The CO2 transmitter uses the principle of non-dispersive infrared (NDIR) to detectthe presence of CO2 in the air. It combines mature infrared absorption

gas detection technology with precise optical path design and sophisticated circuitdesign, and has a built-in temperature sensor for temperature

compensation has good selectivity, no oxygen dependence, and long service life.

2. Product Features

1. High sensitivity and high resolution

2. Low power consumption and fast responsetime

3. Temperature compensation, excellent linearoutput

4. Excellent stability

5. Long service life

6, anti-water vapor interference

3. Product application

Can be widely used in HVAC and indoor air quality monitoring, industrial process and safety protection monitoring, small weather stations, agricultural

greenhouses, environmental computer rooms, grain depots,aquaculture, flower farming, commercial building control, office buildings,schools, conferences

Monitoring of CO2 concentration in production processes of rooms, shopping malls, restaurants, gyms, cinemas and animal husbandry.
