Gas detectors GS-220.B.V are monitoring levels of combustible, toxic or refrigerant gases.
Different principles of detection with catalytic, semiconductor or electrochemical sensor elements are used.
Reliable operation of the detector is ensured by the self-diagnostic function, which constantly monitors the condition of the sensor and signal lines and alerts in case of fault.
Sensor calibration is done remotely with magnetic key without opening the enclosure that facilitates periodic inspection and maintenance.
Gas sensors GS-220.B.V are in a metal housing with IP 65.
