Overview
The LabCompanion TH-608-10 High-Low Temperature Cycling Chamber is an engineered environmental test system designed for precise, repeatable thermal stress evaluation of materials, components, and finished products across extreme temperature regimes. Based on forced-air convection with dual-stage refrigeration and PID-controlled electric heating, the chamber delivers controlled, programmable temperature transitions between −70 °C and +150 °C—enabling simulation of real-world thermal aging, storage, transportation, and operational conditions. Its robust architecture supports both static temperature holds and dynamic ramp-and-soak cycling profiles, making it suitable for reliability validation in electronics, automotive, aerospace, medical device, and polymer industries. The system complies with core environmental testing standards including IEC 60068-2-1 (cold), IEC 60068-2-2 (dry heat), and MIL-STD-810H Method 502.7 (low temperature) and Method 501.7 (high temperature).
Key Features
- High-fidelity temperature control: ±0.5 °C fluctuation and ≤2.0 °C uniformity across the full working volume, verified per IEC 60068-3-5 calibration protocols.
- Programmable thermal ramping: Adjustable heating and cooling rates from 1 to 25 °C/min—configurable as linear or non-linear segments within multi-step test sequences.
- Stainless steel inner chamber (800 × 950 × 800 mm) with double-wall insulation and silicone-sealed door gasket for low thermal leakage and long-term stability.
- Intelligent microprocessor controller with 32-segment programmable memory, real-time data logging, and USB export capability for traceable test records.
- Dual-circuit safety system: Independent mechanical overtemperature cut-off and electronic fault detection with audible/visual alarm and automatic shutdown.
- Compliant with ISO 9001:2015 quality management requirements; design and manufacturing documented under internal GLP-aligned procedures for audit readiness.
Sample Compatibility & Compliance
The TH-608-10 accommodates a broad range of sample types—including PCB assemblies, lithium-ion battery cells, elastomeric seals, pharmaceutical packaging, and composite structural panels—without compromising thermal fidelity. Its interior geometry allows for standardized mounting via adjustable stainless steel shelves (supplied) and optional load carts. All electrical and refrigeration components meet CE marking requirements for EMC and LVD directives. While not certified for Class II medical device sterilization or explosive atmospheres, the chamber is routinely deployed in FDA-regulated environments where thermal validation protocols follow 21 CFR Part 11-compliant data integrity practices. Test reports generated from its controller are compatible with IQ/OQ/PQ documentation frameworks used in GMP and ISO 13485 settings.
Software & Data Management
The integrated controller supports local operation via intuitive touchscreen interface and remote supervision through optional Ethernet or RS-485 connectivity. LabCompanion provides a Windows-based PC software suite (compatible with Windows 10/11) that enables advanced profile editing, real-time monitoring, alarm history review, and CSV-formatted data export. All logged temperature points include timestamp, setpoint, actual value, and deviation—structured to support ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available). Audit trails record user login/logout events, parameter modifications, and cycle start/stop actions—meeting baseline requirements for regulated laboratory environments requiring data integrity assurance.
Applications
- Thermal cycling qualification per JEDEC JESD22-A104 for semiconductor packages and interconnects.
- Accelerated life testing of adhesives, conformal coatings, and encapsulants under alternating thermal stress.
- Validation of cold-chain packaging performance for biologics and temperature-sensitive diagnostics.
- Material coefficient of thermal expansion (CTE) screening using dimensional metrology before/after exposure.
- Pre-conditioning of sensors, actuators, and optical modules prior to functional testing at ambient extremes.
- Environmental stress screening (ESS) for military-grade hardware per MIL-STD-2164A guidelines.
FAQ
What is the maximum allowable sample mass for stable thermal performance?
The chamber is rated for up to 50 kg total load without significant degradation in uniformity or ramp rate—assuming samples are evenly distributed and do not obstruct airflow grilles.
Does the TH-608-10 support humidity control?
No. This is a dry-temperature-only chamber. For combined temperature/humidity testing, refer to the LabCompanion THU series environmental chambers.
Can test profiles be exported and imported between units?
Yes. Profile files (.lcp format) are fully portable across TH-608-10 units and backward-compatible with firmware version 2.3 and later.
Is third-party calibration certification available?
Yes. LabCompanion offers NIST-traceable calibration services with certificate of conformity, including as-found/as-left data and uncertainty budgets per ISO/IEC 17025 requirements.
What maintenance intervals are recommended?
Refrigerant circuit inspection and filter replacement every 12 months; annual verification of sensor accuracy and controller PID tuning parameters using external reference thermometers.
