Gas detectors GA-300.A are intended for detection of refrigerant gases. Semiconductor sensor elements.

Non intrusive calibration without opening the enclosure using magnetic calibration nozzle UGC-01. 

Plastic enclosure with degree of ingress protection IP65.

Analogue gas detectors GS-300.A are designed to monitor the concentration of freons and ammonia.
