The D12 toxic and combustible gas transmitter can accept up to 46 difference sensors, reducing the requirement of multiple transmitter models.

It has a large LCD display with clear, menu-driven set up pages that show the gas concentrations in large numbers, the alarm indication and a backlight when it is operating in 3-wire mode for increased visibility.

The D12 toxic and combustible gas transmitter has a self-aligning sensor holder that is simply plugged in, with an automatic sensor recognition system that will provide verification when contact is made.

The unique sensor response testing system provides reliable response checks to ensure the integrity of the system, even in outdoor weather conditions. The response is verifed with an actual gas sample that can be generated on demand.

Generators store run time information that is accessible to the operators. They are automatically tested for compatibility with the installed sensor.

Technical information:

  • Sensor type: Electrochemical for toxic gases and oxygen. Catalytic bead for combustible gas
  • Range: User adjustable within limits of selected sensor.
  • Response time: Sensor dependent
  • Accuracy: Generally ±10% of value (limited by available calibration gas)
