AERASGARD® FSTM-CO2-U

Item No. 1501-9122-1001-162
EAN 4 251325 617305

The room sensor AERASGARD® FSCO2/ FSTM - CO2 in the in-wall housing is used for measuring the CO2 content and temperature of the air. It converts the measured values into a standard signal of 0 -10 V.

The CO2 content of the air is measured using an optical NDIR sensor (non-dispersive infra-red technology). A digital, long-term stable sensor is used for temperature measurement.

The in-wall sensor is mounted in high-quality panel switch programmes, ideally of the brands Gira, Berker, Merten, Jung, Siemens or Busch-Jaeger (using in-wall adapters) either individually or in combination with light switches, socket outlets, etc.

It is used in non-aggressive, dust-free environments, in refrigeration, air conditioning and clean room technology, and in interior rooms, such as living rooms, offices, hotels, etc.
