The alarm
device consists of the control and alert
compartment and the probes with
electrochemical and thermocatalytic sensors
Detectable gases:
- toxic: CO, NO2, H2S, SO2, NH3, O2 and
others
- flammable: methane, propane, butane,
acetylene, ethanol, methanol,
acetone, hydrogen and others
There is a possibility to use probes as
separate alarm devices without the control
compartment
Advantages:
- works from 220 V outlet
- simple to install and use
- long life cycle
- small size
- high sensitivity
- digital output RS-485
