Three-chamber thermal shock test chamber, technical parameters of three-chamber thermal shock test. Performance: The performance is measured after stabilizing for 2 hours without test load and no shelf. In addition, the temperature rise and fall time refers to the performance of air-cooled type at room temperature +25℃, under no-load conditions, cold-heat shock test chamber. 2.1 Internal chamber dimensions: W400H350D350 (mm), 50L; 2.2 External dimensions: approximately W1550H1680D1700 (mm) (the external appearance is subject to the final physical product); 2.3 High and low temperature range: A. High temperature section: RT+10℃～+200℃; B. Low temperature section: -10℃～-55℃; C. Shock range: (+60℃～+150℃)/(-40℃～-10℃); 2.4 Test method: Pneumatic damper switching between two or three temperature zones; 2.5 Temperature rising and falling rate: Heating time: +60℃～200℃ in 20min, Cooling time: +20℃～-55℃ in 60min.
