SGI621

The addressable sensor SGI621 is an IP55-rated semiconductor gas detection unit that, coupled with our addressable gas detection controller BXI32, allows to detect a refrigerant gas R290

The sensor is managed by a microprocessor which not only supplies an alarm signal to the control unit connected to it, but also allows execution of a self-diagnosis and therefore an automatic calibration, in order to always have the maximum detection accuracy.
