Intended use

The instrument is intended to continuously monitor ambient
air for toxic or combustible gas concentrations. When the gas
concentration exceeds the defined alarm threshold, the built-
in alarm devices (horn and strobes) of the instrument are
triggered. External alarm devices can also be connected and
triggered by the built-in relays. An integration in an alarm
management system is possible using the 4-20mA interface
or relays.
The instrument is not suitable for operation in hazardous
areas with potentially explosive atmospheres.
