Chapter 9. Features and Specifications
The Model PM880 is a microprocessor-based portable hygrometer designed
to measure dissolved moisture concentration in gases and non-aqueous
liquids. This highly-advanced industrial analyzer is adaptable to many
applications, and is certified intrinsically safe for use in hazardous
locations.
The complete analyzer, including the hygrometer, cables and measurement
probes, forms a “system” designed to monitor a process accurately and
reliably. The following section discusses each part of this system and lists
specifications.
