In the humidity system of constant temperature and humidity test chamber, there will always be cases where the customer's reaction humidity is 100% or the humidity is not coming. This chapter lists the reasons why the humidity of the constant temperature and humidity test chamber is 100% or the humidity is not coming:
1. The dry and wet ball gauze is placed in the wrong position. One of the upper sensors is a dry ball, and the lower one is a wet ball. Under normal circumstances, the gauze must be hung on one of the sensors below, and the lower end of the gauze must be reliably immersed in The water in the water head is so that the wet gauze can absorb water reliably;
2. The wet ball gauze is yellow, or the use time is too long, too much mineral is accumulated on the gauze, which causes the wet gauze to absorb water and the water is not absorbed, so that the detected humidity is not accurate, resulting in a false high humidity. image.
3. The water in the wet bulb is not water or the water level is low, the gauze can not absorb water, and the following parts are mainly checked:
a. Observe whether there is water in the water level box on the side of the sink. If not, it may damage the float ball;
b. The electromagnetic pump is damaged, and the resistance value of the multimeter is used to measure the resistance value, and if it is open circuit, it is damaged;
c. The gap hydration timer is damaged and cannot be replenished properly.
Many of the reasons for the constant temperature and humidity test chamber are due to the customer's own operation. Therefore, we must be familiar with the operation manual when using it to avoid unnecessary troubles. If it is the fault of the machine itself, you should contact the manufacturer in time.
