Constant temperature and humidity test chamber requirements for wet ball gauze
When the humidity constant humidity test chamber is used for the humidity test, there is a customer reaction saying that the humidity is 100%, and it may not reach the displayed value. When we do the humidity test, we need to pay attention to the placement of the wet ball gauze, otherwise it is very likely that the humidity will show 100%. 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 constant temperature and humidity test chamber is not any gauze. Can be substituted, it has certain requirements: 1. The relative humidity reading of the test chamber is based on the difference between temperature and humidity. Strictly speaking, it is also related to the 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. 2. According to the relevant regulations, 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 bulb thermometer, that is, the humidity is correct. 3, constant temperature and humidity test box wet ball gauze placement also has a clear regulation: gauze length 100mm, tightly wound sensor probe, probe from the humidity cup 25-30mm, gauze immersed in the water cup. This will ensure the correctness of the humidity.
