Description
Wall-mounted oxygen sensor
AERASGARD® AO2
The measuring device detects the oxygen content O2 (0-25%) in the ambient air. The transmitter converts the measured value into a standardized, analog output signal 0-10 V.
As an option, the measuring instrument has a backlit, rotatable display and potential-free changeover contact. The version with backlit LCD display shows the measured values and in/max values.

The measuring instrument performs an automatic calibration at regular intervals, which ensures a long-term stable measurement. This can also be performed manually on the instrument at any time.
The oxygen meter is optimally suited for use in workplaces, medical facilities, HVAC applications, greenhouses
