What is Temperature And Humidity Test Chamber?

Small environmental test chamber is a kind of reliability environmental test equipment. It can simulate the natural temperature and humidity conditions in the real environment. It is used to test the performance of materials in various environments and test the heat resistance, cold resistance, dryness resistance and moisture resistance of various materials to improve product reliability.

Products Features

Although the small environmental test chamber is smaller in size, its performance is still stable:
1. Accurate temperature and humidity control: It still uses high-quality heating elements to accurately control the temperature in the test chamber to ensure the stability of the test.
2. Energy saving and environmental protection: It adopts advanced cooling, heating and humidification technology to reduce energy consumption and meet environmental protection requirements.
3. Intelligent control: It is equipped with an intelligent control system, which can preset test conditions, automatically run and record data, and reduce manual operation.
4. Safety protection: It has a variety of safety protection functions, such as over-temperature protection and overload protection, to ensure the safety of the test process.
5. Compact structure: Because it is a small device, it occupies a small area and is easy to move and install.
6. Versatility: It can be programmed according to different needs to achieve switching between multiple test modes.
7. Low noise: The use of high-quality components and optimized design solutions makes the machine run with low noise.

How to maintain Temperature And Humidity Test Chamber?

1. Sample limit: It is prohibited to use this equipment to test samples of flammable, explosive, volatile, and corrosive substances;

2. Equipment placement: The small environmental test chamber should be placed in a place with good air circulation and stable airflow, and should not be affected by external factors such as direct sunlight and heat sources to avoid affecting the accuracy of the test;

3. Use the instrument correctly: Before use, you must first understand the usage and instructions of the equipment and use it correctly according to the requirements of the instructions to avoid misuse that may lead to inaccurate test results;

4. Pay attention when opening the door: It is strictly forbidden to open the box door at will during the test, as high and low temperature air will affect the personal safety of the tester;

5. Pay attention to warning tips: During the test, it is necessary to carefully observe the operating status of the equipment and the on and off status of the indicator lights, and deal with abnormal situations in a timely manner to avoid equipment failure or other accidents;

6. Pay attention to maintenance: It is best to perform regular maintenance after testing to extend the life of the equipment. In this way, the small environmental test chamber can maintain a longer life and run smoothly for a longer period of time.
