TESTO Temperature and humidity measuring instrument set testo 635-2 U-value set

To assess the thermal insulation performance of a building component (walls, windows), you need to know the heat transfer coefficient, or ‘U-value’ for short (formerly K-value). The U-value is the most important parameter for determining a building’s heat loss. Ready to calculate the U-value with the testo 635-2 temperature and humidity meter. The testo 635-2 U-value kit is designed to make calculating the U-value easier than ever before. In addition to the testo 635-2 temperature and humidity meter, you receive the special temperature probe for determining the U-value, as well as the accessories for temperature measurement with wireless data transmission. This allows you to carry out all necessary temperature measurements indoors and outdoors simultaneously: room air temperature, internal wall temperature, and external temperature via wireless transmission. The testo 635-2 temperature and humidity meter then calculates the U-value automatically and displays it on the screen. Thanks to the integrated data logger, you can save the measurement data in the device and subsequently analyse it on a PC using the software. You can store all the equipment neatly in the supplied case or transport it to the measurement site.Further advantages of the testo 635-2 temperature and humidity meter In general, the testo 635-2 temperature and humidity meter is suitable for measuring temperature, air humidity, material equilibrium moisture content and the pressure dew point in compressed air systems. Humidity trends can be recorded and analysed and presented in graphical or tabular form. Thanks to wireless measurement data transmission via radio, up to 3 temperature or humidity probes can be displayed on the meter. Selectable user profiles enable intuitive operation. With the appropriate (optional) probe, material moisture content can be displayed directly. In the PC software, characteristic curves for various materials can be stored and transferred to the temperature and humidity meter. To analyse moisture in ceilings and walls, the meter directly displays the dew point difference between the room air and the wall surface. Precision sensors down to -60°C tpd are available as an option for checking the pressure dew point in compressed air systems.
