Hydrogen Sulfide (H2S) Detectors

PemTech hydrogen sulfide sensors or H2S detectors are designed to monitor the concentration of Hydrogen Sulfide (H2S) in ambient air. Concentration is measured in parts per million by volume (ppm). These h2s sensors are available in electrochemical and solid state metal oxide semiconductor. All hydrogen sulfide sensors feature microprocessor based modular design and are suitable for use in hazardous locations.
