How to choose the material of the test hole of the high and low temperature test chamber

High and low temperature test chambers are divided into two types
: with humidity system and without humidity system.

High and low temperature test chambers are widely used in various industries, and for products that need to be tested with electricity, an optional accessory is required - test lead holes
.

So are the high and low temperature test chambers with humidity and no humidity different for the material of the lead hole? The answer is yes, the high and low temperature box without the humidity system only needs to test the lead hole made of stainless steel; If it is humid, it should not be made of stainless steel
.

Because even the best stainless steel will be affected in the long-term humidity environment, such as the "poor sealing, rust or leakage" of
the test chamber.

When purchasing a high and low temperature test chamber, you only need to explain to the manufacturer that the product needs to be opened, and tell the diameter of the hole to be
opened.

Then the manufacturer will choose the right material
according to whether the equipment has a humidity system.

If it is found that the equipment is equipped with a humidity system, then the material selected is stainless steel
.
