This climate, humidity, and temperature measuring device is suitable for detecting moisture to prevent mold formation. The product measures relevant climate data such as air humidity, ambient temperature, surface temperature, and dew point temperature. The laser circle display allows for precise targeting of the measurement range. When detecting thermal bridges or wall moisture, the user is clearly warned. The auto-hold function freezes the measured value at the end of a continuous measurement on the display. Measurement data can be transferred to a smartphone or tablet using the MeasureNote app via the digital connection interface.
