Key Features:
- Compliant with Industry Standards:Supports test profiles required by GB 31241, GB/T 2423.1, and IEC 60068, including 10+ cycles between -40℃ and +75℃ with 6-hour dwell at each extreme temperature.
- Precise Temperature Control:High-precision sensors and PID control ensure stable temperature holding and accurate ramp rate control, simulating real-world temperature variations.
- Safety-Oriented Design:Optional explosion-proof configuration (pressure relief door, explosion-proof motor, sealed wiring) prevents risks from lithium cell thermal runaway during testing.
- User-Friendly Operation:Touch screen interface allows quick setup of test parameters, cycle counts, and dwell times; supports data logging and export for quality traceability.
- Reliable Air Circulation:Unique duct design eliminates laminar airflow, ensuring uniform temperature distribution across the test chamber.
