Know in advance the common problems of high and low temperature alternating heat and humidity test chamber

We have received a lot of customer calls and asked about operational or technical problems when using high and low temperature alternating heat and humidity test chambers. Below we will answer the more common questions:

1. Does tap water use water during the humidity test affect the machine or test?

A: Generally speaking, tap water is ok. Humidity effect can be achieved, but if tap water is used for humidity water for a long time, scale is easily generated in the water pipe, and impurities in the tap water will also adsorb to the surface of the product, and the water tank will not be clean. In addition, because the tap water humidification particles are relatively large, the humidity test for a long time will inevitably affect the service life of the humidity sensor, which may cause the humidity sensor to be short-circuited. In this regard, the experimental water requirements are relatively strict, using pure water, distilled water or deionized water.

2. Is it possible to open the door midway when conducting high temperature, low temperature and damp heat tests?

A: You can't open the door in the middle. If you open the door in the middle of high temperature or low temperature test, it may cause burns and frostbite to the operator. It will also cause the evaporator on the machine to freeze and the inside of the box to freeze. If the door is opened halfway during the damp heat test, the humidity of the case will drop sharply, which will affect the test results.

3. What is the impact of high temperature and humidity fluctuations on the test?

A: According to the national standard, the temperature fluctuation is ±0.5°C, and the humidity fluctuation is within ±1°C. The fluctuation is too high, which will affect the test data.

In recent years, barstools have become a popular alternative to traditional dining room chairs. Barstools appear recognizable and desirable for their height advantage over typical dining chairs. Typically, barstools give off a more casual dining vibe, especially when coupled with a counter-height table. Many homes also have high breakfast counters that also need barstools.
