Covering a temperature range of –70°C to +150°C, with ±0.5°C stability and ±2.0°C uniformity, it accurately simulates both high-heat and sub-zero conditions for electronics, aerospace parts, automotive components, and advanced materials. Unique to this model, rapid transition between extreme temperatures-up to 5°C/10℃/15℃/min temperature change rate or higher-enables accelerated lifecycle and thermal shock tests. Fully compliant with IEC 60068-2-1/2, MIL-STD-810H, ASTM D618, and other global standards, it supports multi-day continuous testing. The intuitive touchscreen HMI offers 120 programmable segments, curve visualization, USB/ethernet data export, and optional remote monitoring.
Distinctive Strengths of High Low Thermal Temperature Resistance Test Chamber
Extreme Thermal Cycling Capability
Supports high-low transitions from –70°C to +150°C for accelerated life and thermal shock testing.
Rapid ramp rates of 5℃/min (10℃/15℃/min) reduce total test cycle times without sacrificing stability.
Superior Temperature Uniformity & Recovery
Multi-directional forced-air system maintains uniformity ±2.0°C across all samples.
Rapid recovery after door opening-temperature restored within 10–15 minutes, minimizing test downtime.
Energy-Efficient Refrigeration System
Dual-stage cascade compressors with environmental refrigerants ensure continuous operation with 10–15% energy savings.
Intelligent soft-start protects compressors during frequent thermal cycles.
Flexible Sample Capacity & Customization
Interior volumes 100L to 1,000L, adjustable/removable shelves supporting 50 kg per layer.
Optional multi-layer racks, feed-through ports (Φ50–100 mm) accommodate diverse specimen types.
Advanced Control & Monitoring
Touchscreen HMI supports up to 120 programmable segments, data logging, and Ethernet/USB export.
Remote monitoring via PC or mobile ensures oversight during unattended tests.
Safety and Reliability
Over-temperature, compressor overload, and automatic defrost protections ensure safe operation.
Multi-level alarms and emergency stop features secure both samples and equipment during long cycles.
