High and Low Temperature Thermal Shock Chamber can be used in the temperature shock test and fast-changing temperature test in a wide range such as aviation, air space, electronic components and material research.

HLST-500D has two separate chambers: high temperature chamber and low temperature chamber.
HLST-500T has three separate chambers: high temperature chamber, low temperature chamber and test chamber.

Standart:
IEC 60068-2-14 (GB/T 2423.22) “Environmental testing – Part 2-14: Tests – Test N: Change of temperature”
ISO 16750-4 “Road vehicles — Environmental conditions and testing for electrical and electronic equipment — Part 4: Climatic loads”
GJB 150.5A “Laboratory environmental test methods for military material – Part 5: Temperature shock test”
GB/ T10592 “Specifications for high/low temperature testing chambers”

Operation Principles:
HLST-500D: The sample is controlled by a basket and shuttles between the high temperature chamber and the low temperature chamber.
HLST-500T: The sample always stays in the test chamber during the measurement. High temperature chamber prepares high temperature air and low temperature chamber prepares low temperature air. The sample chamber will connect with high temperature chamber for high temperature test and will connect with low temperature chamber for low temperature test. Then, the air in test chamber will reach your target temperature in several minutes (“recover time”).

Main Technical Parameters:

Note: HLST-100D-*: * you can choose three temperature intervals of A/B/C, for example: LISUN model HLST-100D-B, D represents two-chamber type, B represents the temperature range of -40 ℃ ~ 150 ° C; HLST-500T-C, T which represents the three-chamber type and C represents the impact temperature range of -50 ° C ~ 150 ° C. Special working size and shock temperature range can be customized according to customer requirements.
