Dry and Wet Bulb HygroMeter

The wet and dry bulb hygrometer uses two thermometers: one directly measures the air temperature, while the other, wrapped in moist gauze, measures the evaporative cooling temperature. The humidity is then determined by checking a table based on the temperature difference. It is commonly used for environmental humidity monitoring in storage facilities, greenhouses, and laboratories.
Selection
When selecting, consider that the measurement range covers local temperature and humidity fluctuations, the accuracy meets application requirements, the material adapts to environmental conditions, check the calibration certificate to ensure accuracy, and compare the response time to match the usage scenario.
