NAP|66A
NAP-66A is a miniature & low power consumption type of NAP-3A, and is mainly used for gas detectors and leak testers. 66A is a half in height and needs a half in power consumption compared to 3A 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 userfs manual for further information. A measuring circuit for sensor evaluation is the same as NAP-3A.
