Difference between thermal shock test chamber and High-low temperature test chamber 

 

Some users are entangled when ordering test chambers, and they do not know what kind of test chambers are suitable for their own products, and are afraid to buy a wrong one. So understanding the differences between test chambers plays a more important role. Such as the difference between thermal shock test chamber and high-low temperature test chamber.

 

Firstly, the performance feature difference.

Thermal shock test chamber is an adaptability test for products stored, transported, and used in environments where the temperature changes rapidly. The test equipment is mainly used to perform environmental simulation tests on the physical and other relevant characteristics of the product under the conditions of instantaneous changes in high and low temperatures in accordance with national military standards or user-defined requirements. Whether the performance of the product can still meet the predetermined requirements for product design, improvement, identification and factory inspection.

High-low temperature test chamber is suitable for inspecting various performance indicators of the product's parts and materials under high and low temperature (alternating) cycle changes.

 

Secondly, the working mode difference.

Thermal shock test chamber is reflected in the efficiency of temperature change, which can achieve rapid temperature conversion within 5 seconds. Recovery time is 5 minutes. The thermal shock test chamber can realize the continuous temperature shock process from high temperature to low temperature and then to high temperature cycling in a short time.

High-low temperature test chamber is just adjustable temperature. The temperature change rate is determined according to the heating and cooling rate of the test chamber. The heating rate is generally 1 ~ 3 ℃ / min ( However , our heating rate is more than 3 ℃ / min) , and the cooling rate is generally 0.7 ~ 1 ℃ / min ( However , our cooling rate is more than 2 ℃ / min). The temperature conversion takes a relatively long time.
