  • 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.
    In order to evaluate the heat insulation capability of a component (walls, windows), you need to know the heat transfer coefficient, or "U-value" (previously "K-value"). The U-value is the most important value for proving the heat loss of a building.

    With the testo 635-2 thermohygrometer, you have everything you need to start calculating the U-value

    The testo 635-2 U-value set is designed to make calculating the U-value easier than ever. As well as the testo 635-2 thermohygrometer, you also get the special temperature probe for determining the U-value as well as temperature measurement equipment, with transmission of the readings via radio.
    You can therefore carry out all necessary temperature measurements simultaneously, both indoors and outdoors: ambient air temperature, wall temperature inside, outside temperature via wireless transmission. The testo 635-2 thermohygrometer then calculates the U-value automatically and indicates this on the display. Thanks to the integrated reading memory, you can store the measurement data in the instrument and subsequently evaluate it on the PC using the software.
    You can easily stow all the equipment away in the case supplied or transport it to the measuring location.

    Further advantages of the thermohygrometer

    The testo 635-2 thermohygrometer is suitable for measuring temperature, humidity, material equilibrium moisture content and for measuring the pressure dew point in compressed air systems.
    Moisture progressions can be recorded and analyzed or displayed in graph/table format. Thanks to wireless measurement data transmission via radio, up to 3 temperature or humidity probes can be displayed in the measuring instrument. Selectable user profiles make for intuitive operation.
    The material moisture can be displayed directly using the appropriate (optional) probe. Characteristic curves for various materials can be stored in the PC software and transmitted to the thermohygrometer. To analyze moisture in ceilings and walls, the measuring instrument directly displays the dew point distance between ambient air and wall surface. Precision probes up to -60°C tpd are optionally available for checking the pressure dew point in compressed air systems.

                                                    U-value measurement in old buildings

                                                    When redeveloping or renovating old buildings, it is crucial to be able to determine quickly if heat is being lost through the windows and walls. Only then can energy costs be reduced and redevelopment measures carried out efficiently.

                                                    When assessing thermal transmission, e.g. in old buildings in need of renovation, the U-value is one of the most important values. It enables thermal assessment and monitoring of the installed material.

                                                    3 temperature values are required for calculating the U-value:

                                                    • Outside temperature
                                                    • Surface temperature of the internal wall
                                                    • Indoor air temperature

                                                     

                                                    A radio probe is needed to determine the U-value; this is placed in position outside. It transmits the readings to the measuring instrument inside. To measure the surface temperature the three wires of the U-value probe are attached to the wall with plasticine. The air temperature is recorded by a sensor located on the probe plug. The measuring instrument testo 635-2 automatically calculates the U-value from the three values and shows this on the display. The advantage: there is no need for manual calculation; the result is quick and accurate.

                                                    testo 635-2
