This product is a professional level meter with the integrated measurement function of the ambient temperature, humidity, dew point and wet bulb temperature; it is applicable for the temperature and humidity measurement of production workshop, factory warehouses, libraries, offices, laboratories, and the family living rooms and so on; This product uses high-precision, low-power consumption digital temperature and humidity sensors; it is featured by wide measuring range and high accuracy. Dew point temperature: it refers to the air temperature cooled to the state of saturation under the condition that the water vapor content and atmospheric pressure do not change. Figuratively speaking, the dew temperature is the one when the water vapor in the air is changed to the dew. When the moisture in the air has reached saturation, the temperature is the same as the dew point temperature; when water vapor is not saturated, the temperature must be above the dew point temperature. Therefore, the difference between air temperature and dew point can represent the saturation level of the moisture in the air.
