Overview
The LabCompanion TH-1000-25 is a large-volume, high-dynamic-range environmental test chamber engineered for accelerated thermal stress evaluation of industrial components and systems under rigorously controlled temperature conditions. Designed around a dual-refrigeration cascade system with optimized airflow distribution and high-efficiency PID-controlled heating elements, the chamber delivers precise, repeatable thermal transitions across its full operating range of −70 °C to +150 °C. Its 1 m³ internal workspace accommodates full-size automotive ECUs, aerospace avionics enclosures, battery modules, and multi-board electronic assemblies—enabling realistic simulation of real-world thermal cycling encountered during transport, storage, and operational duty cycles. The chamber adheres to fundamental thermodynamic design principles governing convective heat transfer and thermal mass response, ensuring stable boundary conditions suitable for qualification testing per IEC 60068-2-14 (change of temperature), MIL-STD-810H Method 502.7 (low temperature), and Method 503.7 (high temperature).
Key Features
- Large internal volume (1000 × 1000 × 1000 mm) supports full-system-level testing without component disassembly
- Programmable ramp rates from 1 to 25 °C/min—configurable as linear, step, or custom non-linear profiles via embedded controller
- Temperature stability maintained at ±0.5 °C fluctuation and ≤2.0 °C uniformity across the entire working zone, verified per ISO 16750-4 Annex A
- Dual-stage refrigeration system with environmentally compliant R404A/R23 mixed-refrigerant cascade architecture for deep-cold capability
- High-velocity, turbulence-minimized air circulation with adjustable vane diffusers to reduce thermal stratification and shadowing effects
- Integrated over-temperature, over-pressure, and compressor fault protection with audible/visual alarm and automatic shutdown
- Stainless-steel interior chamber with electrostatically painted outer enclosure for corrosion resistance and long-term dimensional stability
Sample Compatibility & Compliance
The TH-1000-25 accommodates samples up to 800 × 800 × 800 mm with total mass ≤150 kg, including sealed enclosures, PCB stacks, molded plastic housings, and lithium-ion battery packs. Its thermal performance has been validated using NIST-traceable PT100 sensors placed at nine standardized locations (per IEC 60068-3-5), confirming compliance with temperature uniformity and deviation specifications under static and dynamic load conditions. The chamber meets structural and safety requirements outlined in EN 61000-6-2 (immunity) and EN 61000-6-4 (emissions), and supports audit-ready documentation for GLP and GMP environments when operated with optional data logging and electronic signature modules.
Software & Data Management
Equipped with the LabCompanion TC-Studio v4.2 control platform, the TH-1000-25 provides intuitive touchscreen operation, multi-segment profile programming, and real-time graphical monitoring of chamber setpoint, actual temperature, and rate-of-change. All test sessions generate timestamped CSV logs with millisecond-resolution data points, including sensor readings, actuator status, and alarm events. Optional FDA 21 CFR Part 11-compliant firmware enables role-based user access, electronic signatures, and immutable audit trails—fully traceable to individual operators and validation protocols. Data export supports integration with LIMS platforms via Modbus TCP or OPC UA interfaces.
Applications

FAQ
What is the maximum sample weight the TH-1000-25 can accommodate without compromising thermal performance?
The chamber supports loads up to 150 kg while maintaining specified uniformity and stability—provided samples are centrally positioned and do not obstruct airflow grilles.
Can the TH-1000-25 perform thermal shock testing between extreme temperatures?
Yes—when configured with optional liquid nitrogen (LN2) assist or mechanical pre-cooling, it achieves transition times <5 min between −55 °C and +125 °C per IEC 60068-2-14, Class 5.
Is third-party calibration certification available?
Factory calibration is performed using accredited metrology equipment; on-site ISO/IEC 17025-certified calibration services are available upon request.
Does the chamber support remote monitoring and control over Ethernet?
Yes—standard Ethernet port enables secure remote access via HTTPS, SNMP alerts, and integration with building management systems (BMS).
What maintenance intervals are recommended for optimal long-term repeatability?
Refrigerant pressure verification every 6 months; condenser coil cleaning quarterly; full system performance verification annually per ASTM E2709.
