What is a walk-in constant temperature and humidity testing machine?
In recent years, with the rapid development of science and technology and industry, walk-in constant temperature and humidity testing machines have become more and more widely used in many fields. Whether it is electronics, auto parts, or the pharmaceutical and food industries, this equipment plays a vital role. This article will introduce in detail the definition, working principle, application fields and comparison of popular models in the market to help readers fully understand this equipment.
1. Definition of walk-in constant temperature and humidity testing machine
The walk-in constant temperature and humidity testing machine is a large-scale environmental simulation equipment that can accurately control the temperature and humidity of the internal environment and is used to test the performance and stability of products or materials under specific temperature and humidity conditions. Different from small test chambers, walk-in testing machines have a larger internal space, and operators can enter them for sample placement or testing, which is suitable for testing needs of large batches or large products.
2. Working principle
The walk-in constant temperature and humidity testing machine achieves precise control of the internal environment through the collaborative work of the refrigeration system, heating system, humidification system and dehumidification system. Its core principles are as follows:
| system components | Function |
|---|---|
| Refrigeration system | Reduce internal temperature via compressor |
| heating system | Increase temperature by electric heating tube or steam heating |
| humidification system | Increase humidity through steam or ultrasonic humidification |
| Dehumidification system | Reduce humidity by condensation or desiccant |
3. Application fields
Walk-in constant temperature and humidity testing machines are widely used in the following industries:
| Industry | Test content |
|---|---|
| Electronics industry | Test the reliability of electronic components in high-temperature, low-temperature, and high-humidity environments |
| Automotive industry | Simulating the performance of automotive components in extreme climates |
| Pharmaceutical industry | Testing the storage stability of drugs and medical devices |
| food industry | Study the shelf life of food under specific temperature and humidity conditions |
4. Comparison of popular models in the market
According to the search data of the entire network in the past 10 days, the following is a comparison of the popular walk-in constant temperature and humidity testing machine models and their parameters on the market:
| Model | temperature range | Humidity range | Volume | Brand |
