Application
This detector is used with its analogue output signal or Modbus.
The RNO2 is designed for
gas
detection and contact anywhere in the
building network.
Design Features
Gas measuring, monotoring and warning detector based on state-
of-the-art micro technology for continuous monotoring of the
ambient air to detect nitrogen dioxide.
