The standard wet ball gauze also has detailed requirements. It should be 100mm long and tightly wrapped around the sensor probe. The probe should be 25-30mm away from the gauze groove. The wet ball gauze must be immersed in the water cup to ensure the correct humidity. The wet ball gauze should be replaced regularly, and the wet ball gauze should be removed when doing high temperature tests. When the wet ball gauze becomes yellow or hard, it should be replaced in time.
In addition, the relative humidity reading is based on the difference between temperature and humidity. Strictly speaking, it is also related to the atmospheric pressure and wind speed at the time. The wet bulb temperature display value is related to the amount of water absorbed by the gauze and the evaporation on the surface. These are directly related to the quality of wet ball gauze.

In addition, another reason is that the gauze tank is short of water, so you need to check whether the water system is blocked by scale (if so, the hoses in the water system need to be cleaned, and the water filter needs to be replaced after 3-6 months of use). If there is no water in the water cup or there is a lack of water in the humidification tank, check whether the water pump is working properly.
