HygroTwin 2850 - Overview
Trace Moisture, Relative Humidity, Pressure and Oxygen Analyzer

The HygroTwin 2850 Analyzer System combines powerful features and maximum flexibility for accurate moisture analysis in a variety of process control applications. The instrument incorporates two input channels for moisture, two input channels for temperature, and two additional inputs for trace oxygen, pressure, or other sensors.

The HygroTwin 2850 uses interchangeable probes to measure dew point temperatures in gases and non-conductive liquids from –110°C to +20°C (-166°F to +68°F) or 1 ppbv to +20°C (68°F), relative humidity from 0-100% or dew point range from <-15°C to +85°C (<5°F to +185°F). The analyzer receives the moisture and temperature frequency signals from the probes and calculates the engineering units from a calibration table in the probes’ memory. Thirty-one individual units of measure may be selected to indicate dew point, concentration, water vapor pressure, mixing ratio, absolute humidity, relative humidity, oxygen concentration and temperature. The HygroTwin can calculate change in moisture between two measurement points and express it in terms of absolute humidity or concentration units in lbs/MMSCF. This is useful in monitoring drying processes.
