The Product Description:
Under the condition of equal pressure, the water vapor in the gas is cooled until the condensed phase appears. By controlling the temperature of the dew layer of the dew layer sensor, the water vapor and the flat surface of the water are in a state of thermodynamic phase equilibrium, and the temperature of the dew layer is accurately measured, that is, The dew point temperature of the dew layer. An instrument that measures the dew point temperature of water vapor in a gas is called a dew point meter.
Optidew 401 Chilled Mirror Precision Dew Point Meter is powerful, it is a high precision optical dew point measuring instrument. Based on the principle of optical dew point measurement, its performance is stable. Provide the range of -60~90℃ dew point. It can be widely used in industrial and laboratory application requirements. Trial for accurate and continuous measurement of dew point, temperature and humidity or other humidity-related parameter measurement required in the process.
