There are several possibilities for the humidity display in the constant temperature and Humidity Chamber to show 100% RH, which can be solved by checking them one by one.
1. Check whether the temperature sensor and humidity sensor are installed on the opposite side.
2. Check whether the gauze is hung on the temperature and humidity sensor of the box. The sensor near the sink is a humidity sensor. The gauze should be hung over the humidity sensor and wrapped around the temperature sensing part of the sensor.
3. After the gauze is placed, check the gauze to see if it can absorb water normally, whether the gauze is wet, whether the bottom of the gauze is immersed in the Water Tank, and whether there is water in the Water Tank. Please check and exclude the above points one by one. If the problem is still not resolved, continue to review the suggestions below and replace the gauze if it is not absorbent.
4. If none of the above three solutions can solve the problem.
