The testo 605-H1 thermal hygrometer ensures reliable measurement of humidity and air temperature and calculation of the dew point. The&nbsp; permanently mounted probe shaft makes it is an ideal instrument to check measurements in ventilation ducts.

The testo 606-2 moisture meter for material moisture with relative humidity and air temperature measurement allows you to measure the moisture content in wood and building materials – and the surrounding environment too. This means that you can now also check the storage and drying conditions quickly and easily.

The testo 608-H1 digital thermohygrometer equips you to constantly keep an eye on the indoor climate and displays the current temperature and humidity values continuously.

The testo 608-H2 thermo hygrometer with a large, easy-to-read display to measure the air temperature,humidity and dewpoint. In addition, the visual alarm of the hygrometer indicates you when a threshold is exceeded.

The handy testo 610 thermo-hygrometer proves to be an excellent measuring instrument when it comes to fast, precise measurement of temperature and humidity in indoor areas. In addition, the compact instrument also calculates the dew point and the wet bulb temperature as well.

The testo 622 digital hygrometer and barometer is ideal for measuring air temperature, relative humidity and air pressure at once. Aids in monitoring the ambient air, especially in laboratories during calibration or when running experimental setups.

The elegantly designed testo 623 hygrometer provides you with a quick and convenient means of measuring the indoor temperature and humidity in offices, living spaces and commercial premises and logs the readings over a period of 90 days.

The testo 635-1 for temperature and humidity measurement with its State-of-the-art technology and large selection of probes allows you to measure temperature, air humidity and dew point – in compressed air as well.

The testo 635-2 temperature and humidity measuring instrument with its leading-edge technology and wide selection of optional sensors helps you in carrying out temperature and material moisture measurements on a variety of different materials, surfaces and environments.

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.
