MF420-IR-LC

The measuring system MF420-IR AL determines by using a specific two-beam infrared photometer (NDIR) , developed and produced by our company, the absolute CO2 concentration in the ambient air (atmospheric partial pressure). The device is constantly self-monitoring. The system reports malfunctions of hardware and software and is low-maintenance under normal applications thanks to the NDIR technology - we recommend at least an annual inspection.

The device has an analog signal output with 4 - 20 mA or 0. - 10 V for transmission according to the specifications of the user in a downstream device.
