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.
