Wet Bulb Dry Bulb Thermometer

1.Working Principle of Wet Bulb Dry Bulb Thermometer

Wet Bulb Dry Bulb Thermometer is a mechanical ventilation dry bulb thermometer used to measure the temperature and relative humidity of the air.Fully wind up the spring of the Wet Bulb Dry Bulb Thermometer's ventilator and rotate the fan to provide a certain speed of air flow through two side-by-side thermometers, one of which has its mercury bulb wrapped with wet absorbent gauze.

Due to the evaporation of water on the gauze, the temperature of the thermometer drops. By comparing the temperature difference between the two thermometers (wet and not wet), the relative humidity, absolute humidity, etc. of the air can be calculated by looking up the table.

2. Main Applications of Wet Bulb Dry Bulb Thermometer

Measure the temperature and relative humidity of the air. Its structural characteristics are more suitable for measuring the temperature and relative humidity of the air in the field without power supply.
