Which determines the advantages and disadvantages of the constant temperature and humidity test chamber and how to use it safely

The constant temperature and humidity test chamber can simulate the test conditions of different environments such as high temperature and high humidity, high temperature and low humidity, low temperature and low humidity, and is suitable for testing the heat resistance, dry resistance, humidity resistance and cold resistance of materials to determine the product's aging resistance and special environment resistance, The performance of the programmable constant temperature and humidity testing machine is widely used in electronics, communications, chemical, plastic, rubber and other manufacturing industries.

1. The safety and reliability of the test equipment.

Environmental tests, especially reliability tests, have a long test period. The objects of the test are sometimes high-value military products. During the test of the xenon lamp weatherproof test chamber, the testers often have to perform inspections or test work around the site, so the environment is required the test equipment must have the characteristics of safe operation, convenient operation, reliable use, and long working life. The xenon lamp weather-resistant test chamber ensures the normal progress of the test itself, various protections, alarm measures and safety interlocking devices for the constant temperature and humidity test chamber of the test equipment It should be perfect and reliable to ensure the safety and reliability of the test personnel, the product under test and the test equipment itself.

2. The controllability of environmental parameters.

The environmental conditions provided by any environmental test equipment must be observable and controllable. The UV aging test chamber is not only to limit the environmental parameters within a certain tolerance range, but also to ensure the reproducibility and reproducibility of the test conditions. Repeatability is required, and it is also necessary from the safety of product testing. The UV aging test chamber is to prevent the environmental conditions from being out of control and causing damage to the tested product and causing unnecessary losses. At present, various test specifications generally require parameter testing. The accuracy should not be less than one-third of the error allowed by the test conditions.

3. The reproducibility of the environmental conditions of the high and low temperature test chamber.

It is impossible to achieve a complete and accurate reproduction of the environmental conditions that exist in nature in the laboratory. However, within a certain tolerance range, people can accurately and approximate the simulation of engineering products. The external environmental conditions experienced in the process of use, storage, transportation, etc., this paragraph is summarized in the language of engineering, which is "the environmental conditions (including platform environment) surrounding the tested product created by the test equipment should meet requirements for environmental conditions and their tolerances specified in product test specifications".

The safe use management system of the constant temperature and humidity chamber laboratory.

1. The person in charge of the laboratory shall be fully responsible for the safety management of the laboratory, check the safety of the laboratory regularly (once a month), keep a record of the safety inspection, and organize the laboratory personnel to study the documents related to the safety of the high and low temperature chamber, regulations and formulate relevant safety precautions.

2. In order to ensure the safety of all experimenters and the company’s property from damage, the experimenters must firmly establish the "safety first" idea.

3. Laboratory technicians shall concurrently serve as safety officers of the laboratory under their control, and shall be specifically responsible for the safety of the laboratory, and shall frequently check the unsafe factors of the laboratory to eliminate hidden accidents in time.

4. Laboratory staff should be proficient in the use of fire-fighting equipment, and place the fire-fighting equipment in the laboratory in a dry, ventilated, obvious and easy-to-use location. No sundries are allowed around, and it is strictly forbidden to use fire-fighting equipment for other purposes.

The laboratories using inflammable, explosive and highly toxic and dangerous goods must go through the formalities strictly in accordance with the relevant systems and formulate relevant safety measures, and the relevant personnel shall implement them carefully.
