Space Mounting Carbon Dioxide Sensor with 0/10Vdc output

RCO2

£267.50

Description

This self-calibrating microprocessor-controlled CO²  measuring instrument is used for the detection of CO² content in air within a range of 0 ppm to 2000 ppm CO².

Measuring signals are converted into standard signals of 0 – 10V.

The CO² content of air is determined by a NDIR sensor.

Self-calibration of the CO² measurement takes place in cycles of 7 days. In order to ensure this function, the device must be exposed to fresh air (CO² content 300…400ppm) at least once every 7 days.
