Testo 645 Humidity and Temperature Measuring Instrument

Overview

The Testo 645 high-precision humidity and temperature measuring instrument offers two probe inputs for attaching a comprehensive range of probes: Channel 1 accepts temperature probes (TC Type K/J/S and NTC), while a second channel takes humidity and further probes, making it a flexible platform for demanding climate measurement.

At the touch of a button, the thermohygrometer automatically indicates temperature, relative humidity, dew point, pressure dew point, absolute humidity, degree of humidity and enthalpy, along with minimum, maximum and mean values and the last measured value. Convenient evaluation of measurement data is possible using the optional PC software, and data can be printed directly at the measuring location via the optional testo fast printer.
