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.

If you need a measuring instrument for accurate temperature measurement or you would like to measure the temperature in several locations simultaneously, the testo 735-1 is the ideal equipment for you. The wide selection of optional probes enables flexible use of the temperature measuring instrument, for example to calibrate stationary temperature probes, in the electronics and food industries or in laboratories.

Calibration of static temperature sensors, temperature measurements in the cosmetics industry, chemical laboratories, the field of cooling and refrigeration technology, the food industry: the testo 735-2 multichannel thermometer can master virtually any application thanks to a wide range of optionally available sensors, a super-size memory and wireless data transfer.
