ST-48 Hydrogen Sulfide Combustible Gas Monitor 0-30 ppm
Item #: 95122
The ST-48 Combustible Gas Monitor is ideal for facilities that require continuous monitoring of hydrogen sulfide. The enclosure is specifically designed to prevent an explosion. The monitor is well suited for environments such as refineries, natural gas locations, wastewater treatment plants, chemical plants, and any locations requiring LEL gas monitoring for combustible gases. The monitor is housed in a NEMA 4 explosion-proof enclosure suitable for Class 1, Group B, C, and D, Class 2, Group E, F, and G. PureAire’s durable, long-life LEL catalytic sensor will last 5-6 years in a normal environment without needing to be replaced.

2 Configurable High/Low Relays
Long Life LEL Catalytic Sensor Average, 5-6 years
The ST-48 LEL gas detector is housed in a NEMA 4 Explosion Proof Enclosure and is available for hydrogen sulfide (H2S). Capable of monitoring the percentage of LEL combustible gas, the ST-48 is a perfect monitoring solution for providing worker protection in natural gas locations, paper mills, wastewater treatment facilities, the oil and gas industry, and other areas requiring hazardous monitoring for hydrogen sulfide.
The instrument’s fault supervision circuitry continuously monitors for failed sensor cell and communication. Our sensor cell operation is continuously supervised 24/7, and when used with distributive control systems or PLCs, the monitor provides immediate fault identification.
The PureAire ST-48 Hydrogen Sulfide Combustible Gas Monitor incorporates sophisticated electronics that, when used in conjunction with distributive control systems or PLCs enable you to quickly identify and correct major system faults. These enhanced self-diagnostic capabilities include missing cell and broken transmitter wiring. Should a system error occur, the ST-48 Combustible Gas Monitor outputs a 4-20 mA signal to remote alarm/control systems to immediately alert control room personnel.
