The 3-zone thermal shock testing chamber has a high-temperature zone, a low-temperature zone, and a testing zone. It is used to test the degree to which a material can endure in a continuous environment of high temperature and low temperature in an instant so as to test its chemical changes or physical damage caused by thermal expansion and contraction in a short period of time.
