Overview
The LabCompanion TH-408-7 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 dual-refrigeration cascade cooling and high-efficiency forced-air convection heating architecture, the chamber delivers precise, repeatable, and programmable thermal transients—enabling accelerated life testing, thermal shock simulation, and qualification per MIL-STD-810H, IEC 60068-2-14, and JEDEC JESD22-A104. Its robust thermal mass management and optimized airflow distribution ensure stable setpoint attainment and minimal thermal lag across the full operational range of −70 °C to +150 °C.
Key Features
- Programmable ramp rates from 1 to 25 °C/min in both heating and cooling directions, supporting linear, step, and custom non-linear thermal profiles
- High-stability temperature control with ±0.5 °C fluctuation and ≤2.0 °C uniformity across the 800 × 850 × 600 mm working volume
- Cascade refrigeration system with environmentally compliant R404A/R23 dual-stage refrigerant circuitry for reliable sub-zero operation down to −70 °C
- Industrial-grade stainless-steel interior and insulated double-wall construction with low-thermal-conductivity polyurethane foam (≥120 mm thickness)
- Integrated safety interlocks including over-temperature protection, compressor high-pressure cutoff, and door-open alarm with automatic power cut-off
- Touchscreen HMI with embedded real-time data logging, USB export, and optional Ethernet interface for remote monitoring and SCADA integration
Sample Compatibility & Compliance
The TH-408-7 accommodates a broad spectrum of test specimens—from PCB assemblies and automotive ECUs to aerospace composites and battery modules—without requiring internal fixtures or auxiliary support hardware. Its large internal volume (0.408 m³) and unobstructed access via front-opening double-sealed door facilitate rapid sample loading and spatial flexibility for multi-point sensor placement. The chamber complies with ISO 9001:2015 (quality management), ISO 14001:2015 (environmental performance), and ISO 45001:2018 (occupational health and safety). It supports GLP/GMP-aligned validation protocols, including IQ/OQ/PQ documentation packages, and meets essential requirements for ASTM E145, IEC 60068-3-5, and GB/T 10589–2008 standards.
Software & Data Management
The embedded controller runs LabCompanion’s proprietary TEMPCONTROL™ firmware, offering intuitive profile programming, real-time trend visualization, and event-triggered data capture. All temperature readings are timestamped with millisecond resolution and stored internally with configurable sampling intervals (1 s to 60 min). Data export is supported via USB mass storage in CSV format, compatible with MATLAB, Python pandas, and industry-standard statistical analysis platforms. Optional software add-ons provide FDA 21 CFR Part 11-compliant audit trails, electronic signatures, and role-based user access control—suitable for regulated environments in medical device manufacturing and pharmaceutical R&D.
Applications
- Thermal cycling qualification of semiconductor packages and MEMS devices per JEDEC JESD22-A104E
- Environmental stress screening (ESS) of avionics subsystems prior to flight certification
- Material coefficient-of-thermal-expansion (CTE) characterization through controlled expansion/contraction cycles
- Validation of thermal interface materials (TIMs), conformal coatings, and potting compounds under extreme gradient conditions
- Accelerated aging studies for lithium-ion battery cells and BMS modules under variable-rate charge/discharge thermal coupling
- Reliability assessment of optical enclosures and fiber-optic transceivers subjected to diurnal temperature extremes
FAQ
What is the maximum achievable ramp rate for a full temperature transition from −70 °C to +150 °C?
The TH-408-7 achieves a nominal ramp rate of up to 25 °C/min under no-load conditions; actual performance depends on specimen thermal mass, placement geometry, and profile linearity settings.
Does the chamber support thermal shock testing with air-to-air transfer?
No—the TH-408-7 is a single-zone rapid temperature change chamber. For true two-zone air-to-air thermal shock, LabCompanion recommends the dual-compartment TS series (e.g., TS-150-2).
Is calibration traceability to NIM or NIST available?
Yes—factory calibration certificates are traceable to China’s National Institute of Metrology (NIM); optional third-party NIST-traceable calibration services are available upon request.
Can the controller be integrated into a centralized lab automation network?
Yes—via Modbus TCP or optional OPC UA gateway module, enabling synchronization with LIMS, MES, or test sequence managers in automated validation workflows.
