Overview
The LabCompanion LC-800S High-Low Temperature Alternating Environmental Test Chamber is an engineered solution for precise, repeatable thermal stress evaluation of materials, components, and finished products under controlled cyclic temperature conditions. Designed in accordance with internationally referenced environmental testing standards—including GB/T 10592–2008 (equivalent to IEC 60068-3-5) and GB/T 2423.22–2012 (aligned with IEC 60068-2-14)—this chamber supports both steady-state (constant) and dynamic (programmed ramp/soak) thermal profiles. Its core architecture integrates a high-efficiency dual-stage refrigeration system with a robust heating circuit, enabling stable operation across a wide range of thermal extremes—from −70°C to +150°C—with minimal thermal overshoot and high reproducibility. The chamber’s structural integrity, uniform airflow design, and precision PID-based control ensure compliance with requirements for reliability screening, qualification testing, and accelerated aging studies in electronics, automotive, aerospace, and polymer R&D environments.
Key Features
- Programmable temperature cycling capability with up to 99 segments per test profile, supporting complex multi-step thermal sequences including ramp, soak, and hold phases.
- High-precision PT100 platinum resistance temperature sensors mounted at multiple internal locations for real-time monitoring and feedback control.
- SUS304 stainless steel interior chamber with mirror-finish surface, corrosion-resistant and easy to clean—optimized for long-term stability and contamination-sensitive applications.
- Insulation system combining rigid polyurethane foam (for standard ranges) and high-temperature glass wool (activated above 100°C), minimizing heat leakage and improving energy efficiency.
- Full-featured Korean-made controller with English-language LCD interface, intuitive key-based navigation, and built-in data logging functionality for temperature history.
- Standard safety provisions including over-temperature cut-off, compressor high-pressure protection, phase failure detection, and power-loss recovery with resume-on-power restoration.
Sample Compatibility & Compliance
The LC-800S accommodates samples up to 1000 mm × 1000 mm × 800 mm (W×D×H), with two adjustable stainless steel shelves and a Ø50 mm cable/port access port for external instrumentation interfacing. Optional accessories include calibrated reference thermocouples, humidity integration modules (for future hybrid thermal-humidity configurations), and LAN-enabled remote monitoring adapters. All operational parameters are traceable and configurable to meet GLP/GMP documentation requirements. The system satisfies technical prerequisites outlined in ISO 16750-4 (road vehicles), MIL-STD-810H Method 502.7 (low temperature), and JEDEC JESD22-A104 (temperature cycling), making it suitable for validation under regulated quality systems.
Software & Data Management
While the base controller provides local display, event logging, and curve visualization, optional LAN connectivity enables integration into centralized laboratory data management platforms. Logged data—including chamber setpoint, actual temperature, alarm timestamps, and cycle progress—is exportable in CSV format for post-test analysis. The controller supports audit trail functionality with user-access levels (operator, engineer, administrator), password-protected parameter modification, and automatic timestamping—facilitating alignment with FDA 21 CFR Part 11 requirements when deployed in pharmaceutical or medical device QA/QC laboratories.
Applications
- Thermal cycling qualification of PCB assemblies and semiconductor packages prior to field deployment.
- Material coefficient of thermal expansion (CTE) assessment and solder joint fatigue modeling.
- Validation of packaging integrity under extreme ambient storage conditions (e.g., cold-chain logistics, desert climate simulation).
- Accelerated life testing of lithium-ion battery cells and modules across defined low- and high-temperature boundaries.
- Pre-compliance screening for IEC 60068-2 environmental stress tests in electronics manufacturing.
- Research-grade thermal shock simulation where controlled ramp rates and dwell times are critical to failure mode identification.
FAQ
What temperature range does the LC-800S support?
The LC-800S operates from −70°C to +150°C, with selectable sub-ranges (e.g., −40°C to +150°C) optimized for specific application profiles.
Is the controller compliant with international language and interface standards?
Yes—the Korean-manufactured controller features full English-language menus, alphanumeric keypad input, and standardized IEC 60068-compatible terminology.
Can test data be exported for regulatory submission?
Yes; logged temperature records can be exported via USB or LAN as time-stamped CSV files, supporting traceability and inclusion in IQ/OQ/PQ documentation packages.
Does the chamber support automated start/stop scheduling?
Yes—built-in timer functions allow pre-programmed activation and deactivation, enabling unattended overnight or weekend testing cycles.
What maintenance intervals are recommended for long-term reliability?
Routine inspection of condenser coils, refrigerant pressure verification, and sensor calibration every 12 months are advised—full service protocols align with ISO/IEC 17025 laboratory maintenance guidelines.
