Technical Field

[0001] The utility model relates to the technical field of dew point instruments, in particular to an integrated online dew point instrument. Background Art

[0002] A dew point meter is an instrument used to measure the water vapor content, relative humidity and dew point temperature in the air. It can determine the moisture content in the air by measuring the saturated vapor pressure and actual vapor pressure of water vapor in the air, and calculate the relative humidity based on the dew point temperature. The dew point meter is mainly composed of sensors, display screens and batteries. During the test, the sensor is placed in the test environment, and the instrument will automatically measure the temperature and humidity of the environment, calculate the dew point temperature and relative humidity and other data, and display them on the screen. Dew point meters are widely used in air conditioning, refrigeration, heating, drying and other industries, as well as industrial production, environmental monitoring and other fields.
