1.Working Principle of Wet Bulb Dry Bulb Thermometer
Wet Bulb Dry Bulb Thermometer is used to measure the temperature and humidity of the air. It is convenient to carry and has high precision, which is suitable for field survey.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.
