Product Overview
The Dwyer Series GSTC-N-LCD Nitrogen Dioxide Transmitter is designed to monitor nitrogen dioxide (NO₂) concentrations in mechanical rooms, underground parking garages, loading docks, and other areas requiring diesel engine exhaust monitoring.
The GSTC-N-LCD is the nitrogen dioxide version in a wall-mount configuration and includes an integral LCD display for convenient local readings. Its RS-485 communication interface supports BACnet MS/TP or Modbus® RTU, allowing integration with building management systems and controllers.
The transmitter uses an industrial-grade, field-replaceable sensor. Field calibration can be performed using the A-449 remote LCD service display. When the sensor reaches the end of its service life, the display indicates that replacement is required.
For applications requiring a factory calibration certificate, the GSTC-N-LCD-FC version is available with the certificate included.
