Product information "High accuracy thermohygrometer testo 635"
                        For standard atmospheric environment probe or separate humidity and temperature probes. With calibration protocol and battery. Without probe. The dew point value between the environmental air and surfaces can be determined with separate probes. Relative humidity and temperature are displayed simultaneously, the dew point is determined at the touch of a button. Data is documented using the accessory Testo logging printer.

                                    Temperature probe to determine the U-value with triple sensor technology for measuring the wall temperature. To measure surface temperature, the three wires of the probe are attached to the inner wall using the supplied modelling clay.To calculate the U-value, the outside temperature and room air temperature are required in addition to the surface temperature of the inside wall. With the radio probes (consisting of a radio handle and attachable temperature probe heads), these temperatures can be determined quickly and easily and transmitted to the testo 635.
