1. Working principle of Wet Bulb Dry Bulb Thermometer
Wet Bulb Dry Bulb Thermometer consists of two identical mercury thermometers and a ventilator to measure the temperature and relative humidity of the air.Fully wind up the ventilator of the Wet Bulb Dry Bulb Thermometer and allow the fan to rotate to give a certain speed of air flow through two side-by-side thermometers. The mercury bulb of one of them is wrapped with soaked skim gauze.
The temperature of the thermometer drops due to the evaporation of water on the gauze. Comparing the temperature difference between the two thermometers (wet and not wet), the relative humidity, absolute humidity, etc. of the air can be obtained by looking up the table and converting.
2. Main uses of Wet Bulb Dry Bulb Thermometer
Measure the temperature and relative humidity of the air. Its structural features are more suitable for measuring air temperature and relative humidity in the field without power supply.
