| Aug 5, 2013 — Dwyer Instruments, Inc., the preferred source for your complete range of practical and affordable instrumentation, is announcing the release of its NEW SERIES GSTA CARBON MONOXIDE AND NITROGEN DIOXIDE TRANSMITTERS.
The Series GSTA Carbon Monoxide/Nitrogen Dioxide Transmitters monitor the gas concentration in underground parking garages and loading docks. Carbon monoxide is commonly used to measure the exhaust of gasoline engines, while nitrogen dioxide is used for diesel engines. Field selectable current and voltage outputs allow the transmitter to be used with almost any building management controller. For carbon monoxide units, the user can select the output range to be 0 to 200 ppm or 0 to 500 ppm. 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. | |
