NAP－79A
NAP-79A is a moderately-priced version of NAP-78A, and to be installed in an exhaust duct of a stoking equipment for direct monitoring of the exhaust gas as same as the conventional version NAP-78A. Difference from NAP-78A, the components are minimized (Harness and intermediary PC board have been eliminated) so that this new version NAP-79A can be used for lower-priced stoking equipment. The equivalent performances as NAP-78A are guaranteed when an initial output value is read to set the zero point. Heat cleaning cycles are recommended for NAP-78A, but the cycles can be skipped for NAP-79A if simplified control is required.
