With the continuous increase of test materials, the laboratory space is limited, the small constant temperature and humidity test chamber has more functions and stability than the general temperature and humidity test chamber, and the appearance is small and exquisite. The inner box is as large as the test chamber of the same volume. The function is powerful, the floor space is small, the workmanship is exquisite and beautiful, and the ordinary doors of the office and the laboratory can enter. In recent years, Jerry's small constant temperature and humidity test chamber has been deeply loved by new and old customers. The constant temperature and humidity test chamber is a necessary reliability test equipment for R&D department and quality inspection. The advantages of the small constant temperature and humidity test chamber are convenient and easy to test, and are applied to material testing in various industries (such as testing the performance strength of plastic products, metals and foods in various environments). However, as the time it is used increases, the constant temperature and humidity chamber will also have various failures. In the event of a breakdown, we must find the place where the failure occurred in time, and "the right medicine" can not delay the test time. So how do you repair a small constant temperature and humidity chamber? The following is a technical editor of Shenzhen Jerry Test Equipment Co., Ltd. 1. First of all, you should prepare tools for maintenance such as (multimeter, test pencil, combination screwdriver, needle-nosed pliers, vacuum pressure gauge, B-12 cylinder, refrigerant, pipe, welding tools, etc.). Customer satisfaction is the purpose of our service. Perfect after-sales service enables you to relieve all worries. We firmly believe that a good company sells not only a good product, but more importantly, good service. Shenzhen Jerui Test Equipment Co., Ltd. is responsible for providing the following after-sales services to our products: 1. Technical training: operation, daily maintenance, common fault detection and elimination 2. Regular return visit: equipment inspection, troubleshooting problems, passing zui new news 3. Special reserve support for spare parts and spare parts 4. The after-sales service department provides quick response to repair service 5. Full-time maintenance personnel ensure timely and effective troubleshooting Immunization Using Cell Culture Based Rabies Vaccines Rabies is a viral infection transmitted by saliva of infected mammals, most commonly wild, terrestrial carnivores (e.g., skunks, raccoons, foxes, coyotes) or bats.

2. Find the place where the fault occurred. Here we take the failure of the compressor as an example. The following requirements should be met during maintenance:
a: Check if the dry filter exhaust is normal;
b: Check if the pressure indication of the vacuum gauge is in a descending state and in a vacuum state. If there is no such description, it should stop immediately, check whether the pipeline, gas cylinder and pressure gauge are connected badly, so that the inlet pressure gauge is not in a vacuum state, or the welding is not blocked properly. After clearing the cause and eliminating the fault, the power can be continuously observed. Exhaust in this way can only eliminate most of the air in the capillary, evaporator, suction pipe and compressor in the system, and it is impossible to achieve the purpose of high vacuum of the system, so the repair is completed in a short time. In order to achieve the effect of vacuum.
3. When repairing the small constant temperature and humidity test chamber , it is necessary to weld some parts. When welding, the welding must be carried out according to the original position. Otherwise, capillary blocking may occur, which may affect the cooling effect.
In summary, only the steps and methods for repairing small constant temperature and humidity chambers can be used to test various materials in future tests.
