Co2 Carbon Dioxide Transmitter/Controller

Co² Carbon Dioxide transmitter/controller, 4-20mA/0-10vdc, LCD display


Co2 Carbon Dioxide Transmitter/Controller 0-2000ppm, for use with our gas interlock panels.

Co² (Carbon Dioxide) is the combination of carbon and oxygen, it's released by animals and humans when breathing. It is also released during the complete combustion of fossil fuels like coal, etc.

This is not to be confused with Co (Carbon Monoxide), which is also a combination of carbon and oxygen, this becomes toxic when there is no complete combustion of fossil fuels like coal.

Features

1, This series is designed to monitor and control the indoor air quality

2, uses a patented probe structure for excellent sampling

3, high-performance NDIR digital sensor and circuitry, ensure accurate measurement and temperature compensation

4, stable, reliable and fast response

5, 15 years sensor life without

6, applied digital technology, overvoltage and polarity protection, high reliability and anti-interference ability

7, All electrical terminals are on the inside to avoid any possible any damage to PCB when wiring

8, Multiple outputs selection

9, LCD & function keys can set various parameters, calibrate and adjust output, so the product can be a stand-alone controller.
