Hydrogen Sulfide Gas Detectors from General Monitors are among the most advanced in the world. We introduced the first solid-state sensors to offer single-point calibration, which significantly reduces maintenance time and cost. Our long-life metal oxide semiconductor (MOS) sensors are relied upon for their speed of response, high sensitivity, repeatability, robustness and reliability in a wide range of temperature and humidity conditions. They were the first in the industry to meet the ISA-S12.15, Part I standard, and are ideal for oil/gas drilling rigs, refineries, production facilities and other industrial environments where H2S is present. Our MOS sensors are approved to CSA, and FM requirements, Class I, Div 1, Groups B, C and D areas or ATEX, and GOST; Ex ds IIC T6.
