NAP-66A is mainly used for gas detectors and leak testers. NAP-66A is a half in height and needs a half in power consumption compared to existing sensor so that thinner and lighter-weight detectors can be produced. The following are the basic characteristics but it is recommended to refer to the individual users manual for further information.

* Target gases and concentration
Propan(C3H8): 0.03~ 2.2% (0.03~ 1%)
Iso-butane(Iso-C4H10): 0.03~ 1.8% (0.03~ 0.8%)
