Frequently Asked Questions

What is the Dwyer GSTA-C-D CO gas transmitter used for?

The Dwyer GSTA-C-D is a duct-mount CO and NO2 gas transmitter for indoor air-quality monitoring in parking garages, loading docks, and industrial process applications. It uses an electrochemical sensor to detect engine exhaust from gasoline (CO) and diesel (NO2) vehicles, helping building management systems maintain safe ventilation.

What are the specifications of the Dwyer GSTA-C-D?

The Dwyer GSTA-C-D measures CO (selectable 0-50 ppm to 0-500 ppm) and NO2 (0-10 ppm) with an electrochemical sensor. Accuracy is CO: 2% of reading, NO2: 3% of reading. Output is selectable 4-20 mA, 0-5 V, or 0-10 V. Operating temperature is -20 to +50 °C. Certifications include CE and RoHS.

Where to buy the Dwyer GSTA-C-D in Singapore?

3G Electric supplies the Dwyer GSTA-C-D CO gas transmitter to Singapore. We source this model and handle logistics, customs clearance, and delivery to your facility. Contact our team for pricing and lead time on this duct-mount gas transmitter.

How to calibrate the Dwyer GSTA-C-D gas transmitter?

Calibration of the Dwyer GSTA-C-D is performed via push buttons using the optional A-449 auxiliary display. Dwyer recommends calibration every six months for best accuracy. The electrochemical sensor is field-replaceable with a typical life of 4 years. Zero and span adjustments are made on-site.
