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.
The measuring system is available with standard threshold values as follows: The CO2 concentration is output either a 4 - 20 mA or 0 - 10 V interface for further processing. The device complies with the generic standards EN 61000-6-2 and EN 61000-6-4 and thus the EMC Directive 2004/108/EC. The device thanks to its NDIR-Technology is low-maintenance - we recommend at least an annual inspection. For more details, please refer to the technical data or ask our contact person.
