Product Specification

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 user’s manual for further information.
