Constant temperature and humidity test chamber wet ball gauze correct placement method

Wet ball gauze plays an important role in the humidity perception of the constant temperature and humidity test chamber during the damp heat test. Therefore, the correct placement and maintenance of wet ball gauze must follow certain specifications and steps:
1. Take the wet ball gauze out of the box and cut it about 10cm.
2. Put the lower end of the wet ball gauze into the water tank to soak it (it is easier to sense the humidity), and hang it in or put it on the humidity sensor.
Wet ball gauze maintenance inspection of constant temperature and humidity test chamber: Wet ball gauze must be hung on the wet ball sensor at the upper end, and placed in the wet ball gauze sink at the lower end, so that it can easily absorb the moisture in the water tank and soak. If the wet ball gauze is installed elsewhere, the humidity sensor will not be able to sense the humidity, resulting in an illusion that the humidity is 100% and the humidity cannot be lowered. When doing the humidity test, you must check whether the wet ball gauze is hung. If it is hung, please check if the gauze is wet. If it is baked or the water absorption effect is poor, please replace the wet ball gauze in time.

Medical students can use this model to practice. Doctors can explain the extraction to patients. In addition, the model can also be used for exhibition and other purposes. The human teeth function to mechanically break down items of food by cutting and crushing them in preparation for swallowing and digesting. Humans have four types of teeth: incisors, canines, premolars, and molars, which each have a specific function. The incisors cut the food, the canines tear the food and the molars and premolars crush the food. The roots of teeth are embedded in the maxilla (upper jaw) or the mandible (lower jaw) and are covered by gums. Teeth are made of multiple tissues of varying density and hardness.
