Dwyer Carbon Monoxide/Nitrogen Dioxide Gas Transmitter, Series GSTA/GSTC
The Series GSTA and GSTC Carbon Monoxide/Nitrogen Dioxide Gas Transmitters monitor gas concentrations in mechanical rooms, underground parking garages and loading docks.

The carbon monoxide transmitter is used to measure the exhaust of gasoline engines, while the nitrogen dioxide transmitter is used for diesel engines. 

The Series GSTA features field selectable current and voltage outputs while the Series GSTC features BACnet or Modbus® communication protocol, allowing gas sensing solutions that can be used with almost any building management controller.
Features
  • Add optional integral LCD display by adding -LCD to end of model number (Example: GSTA-C-LCD)
  • Industrial grade replaceable CO or NO2 sensors
  • Field selectable current or voltage output on GSTA models
  • Service display tool for set-up and calibration of models without a LCD
