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.

Nap-50a is a miniature & low power consumption type sensor. Nap-50a is Mainly used for gas detectors. Compared to nap-55a, nap-50a has a lower Alcohol sensitivity to eliminate false alarms caused by alcohol, thus more reliable Gas detectors can be produced with nap-50a. The following are the basic Characteristics but it is recommended to refer to the individual user’s manual for Further information. See nap-66a for measuring circuit for sensor evaluation.
