The radio handle for plug-in sensor heads with TE adapter impresses with its easy handling and international approvals (USA, CA, CL). Radio frequency: 915.00 MHz FSK.

The testo 635-1 temperature and humidity measuring instrument enables you to measure the temperature, air humidity and dew point – in compressed air as well. State-of-the-art technology and a large selection of probes, which are available as an option, enable this wide variety of measuring possibilities.

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.

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.

Use the compact professional humidity module to carry out wireless humidity/temperature measurement with the appropriate radio handle and measuring instrument (both available to order separately).

The humidity module can be attached to various Testo radio handles. It enables a high level of accuracy thanks to the precise humidity sensor.<br />
