Product Overview
The Dwyer GSTC-C-D is a duct-mount carbon monoxide (CO) transmitter designed to monitor gas concentrations associated with gasoline engine exhaust. It is suitable for applications such as underground parking garages, loading docks, mechanical rooms and ventilation systems where continuous CO monitoring is required.
The Series GSTC communicates over 2-wire RS-485 using BACnet MS/TP or Modbus® RTU, allowing integration with building management systems and compatible controllers.
The transmitter uses an industrial-grade, field-replaceable sensor. Field calibration and service can be performed using the A-449 remote LCD service display, which provides setup and calibration functions and indicates when the sensor reaches the end of its operating life.
For the factory-calibrated version, see GSTC-C-D-FC, which carries the same core configuration with a factory calibration certificate.

- Verify the transmitter readings and communication with the connected BMS or ventilation controller.
Frequently Asked Questions
What gas does the GSTC-C-D detect?
The GSTC-C-D detects carbon monoxide (CO), which is commonly monitored for gasoline engine exhaust applications.
How does the GSTC-C-D connect to a building management system?
It communicates over 2-wire RS-485 using either BACnet MS/TP or Modbus RTU.
Is the GSTC-C-D wall mount or duct mount?
The GSTC-C-D is a duct-mount model, designed for in-duct gas monitoring.
Does the GSTC-C-D have an integral display?
No. The GSTC-C-D does not have an integral LCD. The A-449 remote LCD service display provides an interface for setup, calibration and servicing.
Can the sensor be replaced?
Yes. The GSTC-C-D uses an industrial-grade, field-replaceable sensor.
How is the GSTC-C-D calibrated?
Field calibration can be performed using the A-449 remote LCD service display. The service display also indicates when the sensor requires replacement.
Is a factory calibration certificate available?
The standard GSTC-C-D does not include a factory calibration certificate. The GSTC-C-D-FC version includes a factory calibration certificate while maintaining the same core configuration.
