Geopal GP-SA is a stand-alone detector that continuously monitors the gas concentration, whether it is in the 0-100% LEL range (lower explosion level) or the 0-40,000 ppm range, in connection with e.g. refrigerants.

In the Geopal GP-SA detector the sensor signal is converted to a linear output signal of 4-20 mA or 0-5 / 10 V, and the detector is equipped with alarm relays for both low alarm, high alarm and fault.
