Dwyer GSTA-C-D : Duct Mount Carbon Monoxide Transmitter, Selectable 200 or 500 PPM, Selectable Output Signals: 4-20 mA, 0-5 V, or 0-10 V, Normal or Reverse Output, 5-Year Warranty
The Series GSTA Carbon Monoxide Gas Transmitters are designed to monitor gas concentrations in mechanical rooms, underground parking garages, and loading docks. Specifically engineered to measure the exhaust from gasoline engines, these transmitters offer versatile gas-sensing solutions compatible with most building management controllers through field-selectable current and voltage outputs.
Benefits/Features
- Easy Maintenance: Industrial-grade, replaceable electrochemical sensors with a typical lifespan of two years.
- Inventory Efficiency: Field-selectable outputs reduce the need for multiple units.
Applications
- Ventilation monitoring in garages or loading docks.
- Air quality monitoring in mechanical rooms.
