S4100C Combustible Gas Detector

The S4100C Intelligent Sensor is a self-contained microprocessor-based transmitter with integral three-digit readout. It is designed to measure and display concentrations of combustible gases in the 0-100% LEL range, but will continue to display concentrations up to 120% LEL. The sensing element may be incorporated in the transmitter housing or remotely mounted at distances up to 620 meters. The S4100C records the number of successful calibrations, computes the sensor output in mV during calibration and stores in non-volatile memory.
