Part No. GSTA-N-LCD
Product Overview
The Dwyer GSTA-N-LCD is a Series GSTA nitrogen dioxide (NO₂) transmitter designed for monitoring diesel-engine exhaust in underground parking garages, loading docks and mechanical rooms. It provides field-selectable analog outputs including 4-20 mA, 0-5 V, 0-10 V, 1-5 V and 2-10 V for connection to building management and ventilation control systems.
The transmitter includes an integral LCD display for local readings, while internal DIP switches allow the output signal to be inverted when required. The standard nitrogen dioxide range is 0-10 ppm. An industrial-grade field-replaceable sensor supports long-term service, and field calibration can be performed using the A-449 remote LCD service display. The display also indicates when the sensor reaches the end of its service life and requires replacement.
The GSTA-N-LCD-FC carries the same core configuration with a factory calibration certificate.

How to Specify & Commission It
- Confirm that the application requires nitrogen dioxide (NO₂) monitoring and select a suitable wall-mount location.
- Install the transmitter according to the manufacturer's installation requirements.
- Select the required analog output: 4-20 mA, 0-5 V, 0-10 V, 1-5 V or 2-10 V.
- Configure output direction using the internal DIP switches if an inverted signal is required.
- Wire the power supply and selected analog output to the building management, ventilation or control system.
- Use the A-449 remote LCD service display for field calibration when required, then verify the transmitter reading and controller response.
Frequently Asked Questions
