When the constant temperature and humidity chamber is running, a humidity EGO error alarm occurs. What should we do to clear the alarm? There are two reasons for the humidity EGO alarm. 1. Humidify drum is dry and over-temperature protected due to lack of water; 2. Humidity EGO device is working abnormally. Solution: 1. Humidify drum lack of water, dry burning and over-temperature protection Check whether there is water in the humidify drum and water cups. If there are no water, check the waterw...

Refrigeration compressors can be divided into two types: semi-hermetic and fully hermetic refrigeration compressors according to their structural methods. 1. Environmental test chamber fully enclosed refrigeration compressor Fully enclosed refrigeration compressor advantage: The refrigeration compressor and motor of the environmental test chamber are installed in a shell that is welded or brazed, and share a main shaft. This not only eliminates the shaft seal device, but also greatly reduces the...

The information of sensor for constantconstant temperature and humidity chambersis the calculation time and the lowest level information of the electronic control unit. It is also a very important sensor in the electronically controlled heating and cooling system. The failure of this sensor will cause the equipment to fail to operate normally or even start. Most of the old-fashioned sensors use magnetic induction crankshaft position sensors. Most of the magnetic induction crankshaft position sen...

The water test chamber not only has very strict requirements on the environment when used, but also has standard regulations on the experimental water being tested, because the water quality selected for use as an experiment can also directly affect the test results. Therefore, after selecting a water test chamber with good durability, it is necessary to select experimental water suitable for testing to facilitate various tests. Request distilled or deionized water Be sure to use distilled or de...

When using a vacuum oven to test products, you need to pay attention to the following points: 1. The sample is placed in a vacuum oven and vacuumed to remove the air components that can be extracted from the material of the sample. If the sample is heated first, the air will expand when heated. Since the sealing of the vacuum oven is very good, the huge pressure generated by the expanding air may cause the tempered glass of the observation window to burst. This is a potential danger. This danger...

here are two defrosting methods for thermal shock test chambers: one is by time, and the other is by the number of cycles. Generally, most manufacturers and customers rarely use set time to defrost, because the disadvantage is that after the set defrost time is up, the chamber may be undergoing testing, and setting according to the number of cycles means defrosting after the hot and cold shock test is completed, so it is recommended to set according to the number of cycles....

According to customer feedback, sometimes when using a reliability climate chamber for humidity testing, the machine will display a humidity of 100% or the actual humidity cannot reach the set humidity. Here is an introduction to how to solve this problem. If the humidity shows 100% or fails to reach the set humidity, it is usually caused by the incorrect placement of the wet ball gauze. Of course, it may also be caused by the wet ball gauze not meeting the requirements. The wet ball gauze used...

The stability of a drug specifically refers to its ability to maintain the same physical and chemical properties and biological properties. If the stability of the drug is poor, and the quality changes due to component degradation, not only may the efficacy of the drug be reduced, but the generated impurities may also have obvious toxic and side effects, which will affect the safety and effectiveness of the use of the drug. Therefore, the purpose of the drug stability test is to investigate the...

A drying oven is a type of low-temperature convection or forced air oven used primarily in laboratory settings. Specimens, tools and temperature-sensitive chemicals are placed inside a drying oven to slowly and evenly remove moisture. In some lab processes, water can interfere with the desired chemical reaction and skew results, but this water has to be removed at a low temperature so that it doesnt kick-start a heat-related chemical reaction within the specimen. Because it operates at lower tem...
