Monitoring gas concentration

THE new Series GSTA carbon monoxide/nitrogen dioxide transmitters monitor gas concentration in underground parking garages and loading docks.

Field selectable current and voltage outputs allow the transmitter to be used with almost any building management controller. For carbon monoxide units, users can select the output range to be 0 to 200ppm or 0 to 500ppm. Nitrogen dioxide units come with a standard 0 to 10 ppm range. The output can be inverted to read 20 to 24 mA or 10 (5) to 0 VDC using internal dip switches.

To maximize the accuracy of the Series GSTA, the sensor can be field-calibrated using the A-449 remote LCD display. When the sensor reaches the end of its life, the display will indicate that the sensor needs to be replaced.
