The Salwico ST200 is a Gas Detector for combustible gases. All of the important calibration functions are inside of the ST700IR. This ensures that the Salwico ST200 Gas Detector can be calibrated by one person.
The sensor of the Salwico ST200 is a replaceable catalytic oxidation sensor that consists of the detection and reference elements that are provided in a wheatstone bridge. When the Sensor is exposed to gas, the bridge will be unbalanced and an electric signal that is proportional to the gas concentration will be converted to a 4-20mA output signal.
