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.
