Nowadays, in various industries, product quality has become the core factor determining the competitiveness of enterprise brands. If you want to know the quality and environmental adaptability of products, then high and low temperature test chambers are indispensable testing equipment.

The high and low temperature test chamber can accurately determine whether the product has certain problems in high and low temperature environments by simulating its performance under extreme temperature conditions.

In fact, many industries widely use high and low temperature test chambers in their research and development and production processes. For example:

• When developing new products or mass producing, the electronics industry conducts high and low temperature tests on the product body or components;

• The aerospace industry conducts testing on various equipment to ensure product performance and stability;

• The automotive industry also needs to understand the reliability and durability of body and engine components in high and low temperature environments when assembling them;

• The pharmaceutical industry tests medical devices and drugs to ensure their stability and shelf life at different temperatures.

Regardless of the industry, conducting simulated environmental tests such as high and low temperature on products is an important part of ensuring quality and reducing risks. Therefore, choosing an efficient and easy-to-use high and low temperature testing equipment has become very important for enterprises. This article will provide you with a comprehensive and popular purchasing guide from different perspectives.

How does the temperature test chamber work?

Now let’s first understand the most commonly used working principle of high and low temperature testing and see how it works. The high and low temperature test chamber mainly relies on the collaborative work of the heating system, refrigeration system, temperature control system, and circulating air system.

Specifically, when it is necessary to increase the internal temperature of the test chamber, the control system will activate the heating system, causing the electric heating tube or furnace to start working, thereby generating heat and gradually raising the internal temperature of the test chamber. When it is necessary to lower the internal temperature of the test chamber, the control system will activate the refrigeration system, and the compressor will start working to compress the refrigerant into high-temperature and high-pressure gas. Then, it will become a high-pressure and low-temperature liquid by condenser. After that,it will be depressurized through the throttle valve and enter the evaporator to absorb heat and vaporize, thereby reducing the internal temperature of the test chamber.

If you want to accurately control the temperature inside the test chamber, you cannot do without a temperature control system and a circulating air duct system.

The temperature sensor is responsible for real-time monitoring of the temperature inside the test chamber and transmitting the data to the temperature controller;

The temperature controller compares the set temperature value with the current actual temperature value, and adjusts the temperature inside the test chamber by controlling the operation of the heating and cooling systems.

The circulating air duct system is responsible for ensuring uniform temperature distribution inside the test chamber.

The circulating air duct system rotating the fan, the air inside the test chamber is circulated to ensure that the temperature inside the test chamber is basically consistent.

Why is high and low temperature testing necessary?

Will the performance and service life of the product be affected under different high and low temperature environments. Only by simulating high and low temperature environments can companies understand the performance of their products in such environments.

Which companies need to purchase?

Various industries such as new energy, household appliances, automotive parts, aerospace, consumer electronics, medical devices, battery cells, security lighting, valves and pipelines, wire connectors, etc. use high and low temperature test chambers in research and development, production, and quality inspection.

When should I make the purchase?

During the product development period, new product testing period, product upgrades, and regular quality inspections, it is suitable to arrange testing.

Where can purchase temperature test chamber?

There are currently many brands of high and low temperature test chambers on the market. If you choose imported instruments, you can directly purchase them from ESPEC or its authorized channels; If pursuing cost-effectiveness, manufacturers such as DGBELL can be considered.

How to choose the most suitable model?

Consider testing requirements, volume, temperature range, product type, etc., while evaluating various aspects such as price and after-sales service.

What is the price?

The following important factors determine the price:

• Volume size: The volume size of the inner box determines the price.

• Temperature range: The maximum temperature range supported directly affects the cost.

• Number of boxes: Choosing double-layer, three-layer, or four box options will increase equipment costs.

• Whether customization is needed: If customized production is required, it will also increase implementation costs.

Summarize

Whether choosing domestic or imported testing instruments, the most important thing is to clarify one’s testing needs. I believe that as long as you choose the right brand, you can maximize your work efficiency.
