Dwyer GSTA and GSTC Carbon Monoxide/Nitrogen Dioxide Gas Transmitters
OVERVIEW
DIMENSION
The Series GSTA & 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.
BENEFITS/FEATURES
- Easy field maintenance with industrial-grade replaceable sensors
- Reduced inventory of units with field selectable outputs
- Simplified setup for non-LCD units using the set-up display tool
APPLICATIONS
- Garage or loading dock ventilation
- Mechanical room monitoring
