1 Safety Instructions
•Disconnect power supply before opening
the instrument housing or connecting / disconnecting
sensors.
•Measuring head may get hot during operation.
Instruments built for the SH3 measuring head
supply more power through the measuring head
cable. Therefore you must not connect an SH2
or RP2 measuring head to these display units,
as it will damage the measuring heads.

2 Key Features
Precise and Stable Humidity Measurement
With the 473 Dew Point Mirror you are able to perform precise dew point measurements as well as
measurements of other parameters such as relative humidity. The humidity measurement of the 473 is
based on chilled mirror condensation technology which provides highly precise, stable and repeatable
results.
Remote Measuring Heads with Temperature Probe
The 473 features remote cable mounted measuring head options, the RP2, SH2, SH3 and SHX. They
are designed for direct placement into applications. Measuring heads are available with a PRT for
precise temperature measurement and for the calculation of relative humidity.
Optional Pressure Measurement
Optionally, the 473 can be ordered with internal pressure measurement capability. This enables the
user to measure barometric pressure or pressure at the point of measurement.
LCD Display with Touch Panel
The 473 has a full color LCD touch panel with 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.
Calibration Check Function
Users can check the 473 calibration at any time using the built-in Ice Test function, which provides
instant verification of system accuracy and integrity.
Connect and Go
The system is ready for immediate use.
