The room sensor THERMASGARD
is used for measuring the room temperature, and for setpoint adjustment.
The room sensor HYGRASGARD
is used for measuring the relative humidity and temperature of the air.
The room sensor AERASGARD
is used for measuring the CO

A digital, long-term stable sensor is used for humidity and temperature measurement. Relative humidity [% r. H.] is the quotient of water vapour
partial pressure divided by the saturation vapour pressure at the respective gas temperature. The CO
optical NDIR sensor (non-dispersive infra-red technology). The measuring transducer converts the measured values into a standard signal of 0 - 10 V.
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, no setpoint adjustment possible) 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.
