Wet/Dry Bulb PsychroMeter

The wet and dry bulb hygrometer measures air humidity using two thermometers, one directly exposed to the air and the other wrapped in a moist cloth. When air flows, moisture evaporation causes the wet bulb temperature to drop, and the temperature difference between the wet and dry bulbs reflects the humidity level. It is used for humidity monitoring in environments such as greenhouses, warehouses, and workshops.
Selection
When selecting, pay attention to the thermometer's accuracy and ensure the range matches the usage environment. The gauze material should ensure even water absorption. The ventilation device should maintain a stable airflow to avoid thermal radiation interference. Regularly clean scale deposits and replace the gauze, and use distilled water to minimize measurement errors.
