SRC-C1 - Indoor CO2 Transmitter / Monitor -


Indoor CO2 transmitter / monitor

The CO2 concentration is measured through non-dispersive infrared (NDIR) waveguide technology with ABC automatic background calibration algorithm. The applied measuring technology guarantees excellent reliability and long term stability. The microprocessor samples the CO2 once per second. It calculates an averaging signal over a preset number of seconds and generates the output signal. Ranges can also be set by using the external display and programming module (OPA-S).
