Material moisture meters with connectable probes

The testo 635-2 temperature and moisture meter allows you to carry out temperature and moisture measurements on a variety of different materials, surfaces and environments. This is made possible due to leading-edge technology and a wide selection of optionally available sensors.

• Optionally available sensors for moisture, temperature, pressure dew point and absolute pressure measurements

• 2 plug-in sensors and 3 wireless sensors can be connected

• Super-size memory for up to 10 000 readings

• USB cable and PC software for archiving and logging measuring data included

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.

• 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 U-value is the most important value for proving the heat loss of a building. With the testo 635-2 thermohygrometer and compatible accessories from the U-value set, determining the U-value is now easier than ever.

• Evaluate renovation measures quickly and flawlessly

• Easy probe attachment, even in inaccessible places

• Proof of service thanks to report creation 

• Integrated memory and easy evaluation with PC software
