Many friends have reported that small high and low temperature test chambers are sold very expensive nowadays. They are not very clear about why they are sold so expensive, because they are not much different from large high and low temperature test chambers. Therefore, many people have this question. Today, the editor will explore it for everyone.

Firstly, the small high and low temperature test chamber has different temperature range impact functions: it is correspondingly cut off by a multi-stage evaporator structure, controls the evaporation area to match the refrigeration expansion valve, and uses the refrigeration system output to reasonably reduce the output of the heater neutralization, achieving constant energy saving; There is also an independent ventilation valve that operates to introduce ambient air during exhaust (room temperature recovery).

The start time of the experiment can be pre-set, and the test box will automatically start and prepare to start the experiment. After the downwind temperature of the experimental area reaches the exposure temperature, it switches to the next exposure function. Pre processing/post-processing functions. Before or after the start or end of the cyclic test, the sample is exposed to a high temperature environment (heat treatment) for a certain period of time. It can be said that the small high and low temperature test chamber has all the functional and technical parameters of a large test chamber.

Looking at these functional structures, do you think it's like buying a large high-low temperature test box? Moreover, the structure and configuration of a small high-low temperature test box need to be customized separately, and many accessories are not available. This will increase the investment of manpower and material resources in manufacturing and assembly, and the cost may not be lower than that of a large test box. That's why the price of a small high-low temperature test box is not much different from that of a large test box. Seeing this, I believe everyone understands now!
