Nissha FIS Inc. Gassensor SP-42AF-00 für Kältemittel(R32/R410a/R407C/R1234yf/R454C/R454B/R22)

The SP-42AF is a tin dioxide
semiconductor gas sensor
which has a high sensitivity to
HFCs (e.g. Freon: R407C) with
improved cross sensitivity to
other gases. This sensor
maintains strong resistance to
chemical poisoning by a filter
installed inside the sensor


Usage:Refrigerant gas/Industrial leak detector
