Product Options

Overview

The PM880 AC hygrometer is a complete portable system with options and accessories to meet all industrial moisture measurement needs.

This hygrometer is small, lightweight, and easy-to-use. The large LCD displays moisture readings in dew point (°C or °F), ppmv, ppmw, lb/MMSCF (natural gas) and a variety of other unit options. Data can be viewed in alphanumeric or graphic formats. A 120 or 230 VAC power supply allows for continuous operation of the analyzer.
