PureAire - Model ST-48 -Combustible/Toxic Gas Monitor
PureAire’s Combustible/Toxic Gas Detectors are ideal for facilities that require continuous monitoring of toxic or combustible gases in hazardous areas. The enclosure is specifically designed to prevent an explosion. The monitor is well-suited for environments such as refineries, wastewater treatment, parking garages, laboratories, pharmaceutical, research and development, natural gas locations, the oil and gas industry, and any locations where toxic or combustible gases are present.
- Dual Sensor Capability
- Non-Intrusive One-man Calibration
- Ex Proof Enclosure Class 1, Div 1 & 2, Groups A, B, C, & D
- Local Digital Display with Bargraph & Trending
- User Adjustable Dual Alarm Relays
- 4-20 mA Analog Output
- RS-485 Modbus Optional
- NRTL CSA Approvals, ATEX Optional
The Combustible/Toxic Gas Detector’s instrument fault supervision circuitry continuously monitors for failed sensor cells and communication line breaks. Plus, sensor cell operation is continuously supervised 24/7, and when used in conjunction with distributive control systems or PLCs, it provides immediate fault identification for a disconnected sensor cell.
PureAire’s Combustible/Toxic Gas Detector is housed in a NEMA 7 explosion-proof enclosure suitable for Class 1, Division 1 and 2, Groups A, B, C, and D. The gas detector can be used to detect Carbon Monoxide, IPA, Hydrogen, Hydrogen Sulfide, Ethanol, Propane, and other toxic gases. Capable of monitoring ppm levels of toxic gas or % LEL levels of combustible gases, it is a perfect monitoring solution for providing worker protection in chemical plants, refineries, and other areas requiring hazardous classifications.
One or Two Gas Monitoring
PureAire’s Combustible/Toxic Gas Detector electronics can monitor one gas or two different individual gases simultaneously with one transmitter. The Dual Sensor Configuration displays two gas readings and outputs 4-20 mA for each gas to remote controllers.
