1/1 Gas Detectors Sigma ReAct Device discontinued Product code: PW-093-A-SR-X Device withdrawn from production: Gas Detector Sigma ReAct is a stationary device, designed to measure, monitor and detect dangerous levels of reactive gases in the ambient atmosphere. Sigma ReAct is designed as part of the gas safety system Sigma Gas. See full description Product description Supported gases Device withdrawn from production Gas Detector Sigma ReAct is stationary devices, designed to measure, monitor and detect dangerous level of reactive gases in the ambient atmosphere – depending on the gas for which it is intended, the manufacturer selects the type of electrochemical sensor. The device measures the concentration of a given component, and then converts it to electric signal compatible with other devices of the gas detection system. In addition to the measurement, the detector analyses the value of the measured concentration and may provide information about alarms. Sigma ReAct is a selfdiagnostic device – and in the case of detection of malfunctions, it informs the user about it. ammoniacarbon disulfidechlorinehydrogen chloridehydrogen cyanidehydrogen sulfidenitrogen oxidesozone Related products Control UnitsSigma Control LControl Unit ModulesSigma MOD LCD
