 General Information
Reliable Measurement
The Model 473 Dew Point Mirror is a
portable instrument equipped with a separate measuring head for both spot and
continuous measurement of Dew/Frost point and temperature in air and gas
mixtures. Based on the chilled mirror principle, the 473 ensures direct and
accurate humidity measurement.
Full Color Touch Screen
The system uses a full color
active matrix liquid crystal display with an integral touch panel. It has a high
contrast ratio and a wide viewing angle for easy readability. Data is displayed
in large easy to read fonts. Using the on screen buttons and menus, you can
easily configure each line of the display for a variety of humidity,
temperature, and pressure parameters that may be viewed in either SI or non-SI
units. A simple touch of a button toggles any parameter between numeric or graph
format.
Remote Measuring Head
The measuring head is separate
from the control/display unit for use in chambers and other environments of
various humidity/ temperature ranges without the need for external heating of
the gas path. A mounting kit for pipes and tubes, including flowmeter and valve,
is available as an option. For measurement of environment temperature, a
separate temperature sensor is either mounted on the measuring head or available
as a separate remote probe with a connection to the instrument back panel.
Analog & Digital I/O
The 473 is equipped with an
RS-232 digital output and two user-scalable analog outputs for recording or
remote readout of the measured and calculated values.
Verifiable Calibration
Easily check the calibration at
any time using the built-in Ice Test function, providing instant verification of
system integrity.
