Product Overview
The Dwyer GSTC-C is a wall-mount carbon monoxide (CO) transmitter designed for monitoring gasoline-engine exhaust in underground parking garages, loading docks, mechanical rooms and other ventilation applications.
The Series GSTC communicates over 2-wire RS-485 using BACnet MS/TP or Modbus® RTU, allowing integration with building management systems and controllers. Its industrial-grade sensor is field replaceable and can be field-calibrated using the A-449 remote LCD service display. The service display also indicates when the sensor has reached the end of its service life and needs to be replaced.
The GSTC-C does not include an integral display. The A-449 remote LCD service display is used for setup, calibration and service when required.
The GSTC-C-FC version provides the same core configuration with a factory calibration certificate.
