CO2 meter

The microprocessor-controlled CO2 measuring device is used to derect the CO2 content of the air in the range from 0 to 3,000 ppm. The measuring signals are reflected by 6 colored LED´s. The CO2 content is determined by means of an optical sensor, non dispersive infrared technology. By using the sensor according to the dual principle, interferences oft he measurement by pollution and aging can be excluded as far as possible, so that a long function time of the device is ensured. No calibration is needed under normal conditions. The use of the CO2 measuring device is particularly recommended in teaching rooms or conference rooms. A controlled airflow controls the maximum CO2 concentration in the room and keeps it within limits, wich increases the ability to concentrate.
The acoustic signal tone can be switched off or set to different CO2 (900 ppm, 1200 ppm, 1500ppm,1800ppm) values. Standard setting at delivery is 1500 ppm. The following analog outputs are available on the CO2 meter: 0-10 V (factory setting) (2-10V), 4-20 mA (0-20mA).
Included in delivery is a power plug (230V / 24V) and a table stand. The CO2 meter can be mounted on the wall or on a switch box. The table stand ensures that the traffic light is also excellently suited for mobile use.
