Overview
The LabCompanion TH-408-3 Rapid Temperature Change Chamber is an engineered environmental test system designed for high-fidelity thermal stress evaluation of materials, components, and electronic assemblies under dynamically controlled temperature profiles. Based on forced-air convection with dual-stage refrigeration and precision PID-controlled heating, the chamber delivers programmable linear and non-linear thermal ramps across a wide operational range of −70 °C to +150 °C. Its architecture supports accelerated reliability testing protocols—including JEDEC JESD22-A104 (Temperature Cycling), MIL-STD-810H Method 503.5 (Temperature Shock), and IEC 60068-2-14 (Change of Temperature)—making it suitable for qualification testing in aerospace, automotive electronics, semiconductor packaging, and battery module development.
Key Features
- High-speed thermal transition capability: Adjustable ramp rates from 1 to 25 °C/min, configurable as linear or user-defined non-linear profiles for realistic simulation of real-world thermal transients.
- Stable thermal control: Achieves ±0.5 °C temperature fluctuation and ≤2.0 °C uniformity across the full working volume (800 × 850 × 600 mm), verified per IEC 60068-3-5 and ASTM E145-21 Annex A4.
- Dual-refrigeration circuit design with cascade low-temperature stage enables reliable operation at −70 °C without liquid nitrogen dependency.
- Industrial-grade stainless-steel interior and insulated double-wall construction minimize thermal leakage and ensure long-term calibration stability.
- Integrated safety interlocks including over-temperature cut-off, compressor high-pressure protection, and door-open alarm—compliant with EN 61000-6-2/6-4 EMC requirements.
- Modular controller interface supporting RS485, Ethernet, and optional USB data logging; compatible with LabCompanion’s proprietary PC-based test sequencing software.
Sample Compatibility & Compliance
The TH-408-3 accommodates diverse sample configurations—from PCB assemblies and power modules to molded plastic housings and lithium-ion pouch cells—within its spacious internal cavity. Removable shelves and adjustable mounting rails facilitate flexible fixturing. The chamber meets structural and performance criteria outlined in ISO 17025-accredited calibration practices and supports GLP/GMP-compliant validation documentation packages (IQ/OQ/PQ). It is routinely deployed in laboratories operating under FDA 21 CFR Part 11-compliant data integrity frameworks when paired with audit-trail-enabled software options. All electrical and mechanical designs conform to UL 61010-1 and CE marking directives.
Software & Data Management
Control and monitoring are managed via LabCompanion’s Windows-based TestMaster Pro software, which provides intuitive graphical programming of multi-step temperature cycles, real-time curve visualization, and automatic report generation (PDF/CSV). The software implements role-based user access control, electronic signature support, and time-stamped event logging—enabling traceability required by ISO/IEC 17025, ISO 9001:2015, and IATF 16949 quality systems. Optional OPC UA integration allows seamless connection to MES and SCADA platforms for centralized test fleet management.
Applications
- Thermal cycling qualification of automotive ECUs per AEC-Q200 Rev D.
- Pre-conditioning of Li-ion battery cells prior to electrochemical impedance spectroscopy (EIS) or cycle life testing.
- Material coefficient-of-thermal-expansion (CTE) assessment through dimensional metrology during controlled ramp sequences.
- Reliability screening of solder joints in high-density BGA packages using JEDEC-standard temperature profiles.
- Environmental stress screening (ESS) of avionics hardware per RTCA DO-160 Section 4.2 (Temperature Variation).
- Validation of thermal interface material (TIM) performance under repeated thermal shock conditions.
FAQ
What is the maximum allowable sample mass for stable thermal ramping?
The chamber is rated for up to 50 kg total load while maintaining specified ramp rates and uniformity; heavier loads require derating per thermal inertia calculations.
Does the TH-408-3 support humidity control?
No—this model is a dry-temperature-only chamber. For combined temperature/humidity testing, refer to the LabCompanion THS series of environmental chambers.
Can the controller store multiple test programs internally?
Yes—the embedded controller retains up to 100 user-defined programs with stepwise setpoints, dwell times, and ramp slopes.
Is third-party calibration certification available?
Yes—NIST-traceable calibration reports with uncertainty budgets are provided upon request, aligned with ISO/IEC 17025 procedures.
What maintenance intervals are recommended for optimal performance?
Compressor oil and refrigerant filter replacement every 24 months; annual verification of sensor accuracy and door seal integrity per manufacturer’s preventive maintenance schedule.
