Product Description
testo 645 - Humidity/temperature measuring instrument
Order-Nr. 0560 6450
High-precision humidity measurement up to ± 1% RH
Internal reading memory (3,000 readings)
Convenient data evaluation via optional PC software
Possibility of attaching a really wide range of optional probes thanks to a large accessory portfolio
The testo 645 humidity/temperature measuring instrument automatically indicates the measurement parameters of relative humidity, absolute humidity, dew point, degree of humidity, enthalpy and temperature at the touch of a button.
This meter uses a sensor to start up.
Product Description
The testo 645 high-precision humidity and temperature measuring instrument offers two probe inputs for attaching a comprehensive range of probes:
Channel 1: temperature probe, type K/J/S, NTCChannel 2: humidity/temperature probe or Pt 100 temperature probe
At the touch of a button, the thermohygrometer automatically indicates the measurement parameters of temperature, relative humidity, dew point, pressure dew point, absolute humidity, degree of humidity and enthalpy, along with min., max. and mean values, as well as the last measured value. Convenient evaluation of the measurement data is possible using the optional PC software. Measurement data can also be printed out directly at the measuring location via the optional testo fast printer.
Areas of application of the testo 645 humidity/temperature measuring instrumentMonitoring of temperature and humidity values in production, storage and server rooms, museums, archives, cold stores, containers and display casesLocation of mould formation in residential or other buildings
