The humidity and humidity test box will show 100% humidity. It is usually caused by the user's wet gauze placement error. It may also be that the gauze does not meet the specifications. The wet ball gauze used in the equipment is not suitable for any gauze. It has certain requirements. Let's take a look at what it has.
The constant temperature and humidity test chamber also has clear regulations for the placement of the wet ball gauze. The length of the gauze is 100 mm, and the sensor probe is tightly wound. The probe is 25-30 mm away from the humidity cup, and the gauze is immersed in the water cup. This will ensure the correctness of the humidity. And the relevant regulations stipulate that the wet ball gauze must be a special "wet ball gauze" woven into linen, otherwise it is difficult to ensure the correctness of the wet ball thermometer indication value, that is, the humidity is correct.
The relative humidity reading of the constant temperature and humidity test chamber is based on the difference between temperature and humidity, and strictly related to the local atmospheric pressure and wind speed at that time. The wet bulb temperature indication is related to the amount of water inhaled by the gauze and the surface evaporation. These are directly related to the quality of the gauze. I believe everyone has read the above to know how to properly select the gauze of the device. Good gauze is also better able to reflect the equipment, and its role can also be fully exerted.
