testo 0614 1635-D 0614 1635 Temperature sensor; Calibrated to (DAkkS standards) 1 pc(s)

The U-Value (formerly k-value) is the most important value for the heat technical assessment of components. With the new testo 635, this is as easy as never before.
For the calculation of the U-Value are three temperature values required: the outdoor temperature, the surface temperature of the inner wall as well as the ambient air temperature.
With the new wireless sensors can be used for the outdoor temperature quickly and easily with the closed window can be determined. The sensor is positioned just outside and transfers the measured values via radio to the measuring device in the room.
With the new, patented U-value sensor, the two other required temperatures with only one sensor can be determined. For the measurement of the surface temperature, the three wires of the U-value sensor with the putty on the inside wall. The air temperature is determined via a sensor at the sensor plug.
The three required temperatures are determined by the connected temperature sensor and to the testo 635. It calculates the device the U-Value and shows it directly on the display.
