Frequently Asked Questions

What is the Dwyer GSTA-N NO2 gas transmitter used for?

The Dwyer GSTA-N is used for monitoring nitrogen dioxide (NO2) concentrations in underground car parks, loading docks, and industrial emission control. It helps ensure air quality and safety by detecting diesel engine exhaust, with a standard range of 0 to 10 ppm.

What are the specifications of the Dwyer GSTA-N?

The Dwyer GSTA-N uses a high precision electrochemical sensor with a range of 0 to 10 ppm NO2, accuracy of 3% of reading, resolution of 0.1 ppm, and response time under 25 seconds for 90% of step change. It operates at -20 to +50 °C ambient and 5 to 90% RH continuous.

Where to buy the Dwyer GSTA-N in Singapore?

You can source the Dwyer GSTA-N NO2 gas transmitter through 3G Electric in Singapore. We provide procurement, logistics, customs clearance, and delivery services for this Dwyer model, ensuring compliance with local regulations for environmental monitoring systems.

How to install the Dwyer GSTA-N gas transmitter?

Mount the Dwyer GSTA-N using its four Ø5.16mm holes on a wall in the target area, ensuring proper airflow. Connect the universal output (4-20 mA, 0-5 V, or 0-10 V) to your building management system. Calibrate every six months using the remote LCD display and push-button zero/span adjustment.
