General Monitors S4100T H2S Gas Detector

The General Monitors S4100T Intelligent Sensor is a highly reliable, self-contained, microprocessor-controlled hydrogen sulphide transmitter with integral 3 digit readout. It is designed to measure and display concentrations of H2S in the 0-20 ppm, 0-50 ppm or 0-100 ppm range, but will continue to display concentrations up to 120% FSD. The gas sensor may be incorporated in the transmitter housing or remotely mounted at distances of 600 meters. The sensor employs thin film metal oxide semiconductor (TFMOS) technology as the measuring principle.
