Overview

The 473 is the lowest cost RH dew point instrument, yet it has similar performance and the same user interface as our high end instruments. It features cable mounted dew point measuring heads that allow the user to measure directly within the application environment, and includes a temperature probe as standard. Using both measured variables, the 473 is able to calculate, display and output relative humidity. As an option, the 473 can be specified with a barometric pressure sensor. Three different measuring heads with 2 m connecting cables are available (lengths up to 10 m can be provided on some versions on request).

In combination with the T12 multichannel thermometer, the 473 is particularly well suited to climatic chamber validation projects.
