ST-48 Combustible/Toxic Gas Monitor
The ST-48 Combustible/Toxic Gas Monitor is 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-480 Modbus Optional

The instrument’s fault supervision circuitry continuously monitors for failed sensor cell and communication line breaks. Plus sensor cell operation is continuously supervised 24/7 and when used in conjunction with distributive control systems or PLCs, provides immediate fault identification for a disconnected sensor cell.
The ST-48 is housed in a NEMA 7 explosion-proof enclosure suitable for Class 1, Division 1 and 2, Groups A, B, C, and D. The monitor 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, the ST-48 is a perfect monitoring solution for providing worker protection in chemical plants, refineries, and other areas requiring hazardous classifications.
