I wonder if anyone has encountered the phenomenon where the equipment trips or trips the circuit breaker as soon as it is started during the use of a high-low temperature and humidity test chamber. Why does this happen?

Sand and dust test chambers, as crucial environmental simulation devices, play a key role in the reliability testing of military equipment. With modern military equipment becoming increasingly sophisticated and multifunctional, its stability and durability in extreme environments have become critical evaluation criteria.

In the workshops of some enterprises, we often see a brand-new constant temperature and humidity test chamber that, after a short period of use, becomes covered in oil stains and dust.

Temperature control devices in salt spray test chambers regulate temperature variations in the working environment. These devices utilize physical changes within their mechanisms to trigger specific responses, such as opening or closing circuits, thereby achieving automatic temperature control.

Salt-spray corrosion testing is the primary accelerated method for validating the corrosion resistance of materials and their protective coatings. Whether a chamber can continuously generate neutral (NSS), acetic-acid (AASS) or copper-accelerated acetic-acid (CASS) salt fog for 48 h–1 000 h determines the repeatability and reproducibility of the test.
