Overview
The LabCompanion TH-1000-20 is an upright environmental test chamber engineered for high-fidelity thermal cycling and precise humidity control in reliability validation and accelerated life testing. It operates on a dual-refrigeration + electric heating + steam humidification architecture, enabling rapid, programmable transitions between extreme temperature and humidity conditions. The chamber employs a cascade refrigeration system for sub-zero operation down to –70 °C, combined with PID-controlled electric heaters and a stainless-steel steam generator for stable RH modulation across the 20–98% range. Its large internal volume (1 m³) supports full-size automotive ECUs, server racks, PCB assemblies, and multi-component aerospace subsystems—making it suitable for IEC 60068-2-14 (thermal shock), MIL-STD-810H Method 502.7 (temperature), and Method 507.6 (humidity) compliance testing.
Key Features
- Robust mechanical design with double-wall vacuum-insulated construction and high-density polyurethane foam (≥120 mm thickness) for minimized thermal leakage and enhanced energy efficiency.
- Independent dual-loop control: one closed-loop system for temperature regulation (using PT100 sensors with 0.1 °C resolution), and a second dedicated loop for humidity (capacitive RH sensor with NIST-traceable calibration).
- Programmable ramp-and-soak profiles supporting up to 99 segments per test cycle, including linear and non-linear heating/cooling rates from 1 to 25 °C/min—fully configurable via onboard touch interface or remote SCPI command set.
- Integrated safety interlocks: over-temperature cut-off, compressor high-pressure protection, steam generator dry-run prevention, and door-open alarm with automatic power cutoff.
- Standard RS-485 (Modbus RTU) and optional Ethernet/IP or PROFIBUS-DP interfaces for integration into factory-wide MES or LabVIEW-based test automation systems.
Sample Compatibility & Compliance
The TH-1000-20 accommodates samples up to 800 × 800 × 800 mm with standardized mounting rails and optional load-bearing shelves (max. 150 kg distributed load). It meets structural and operational requirements for ISO 17025-accredited laboratories conducting environmental qualification per IPC-9592B (power electronics), AEC-Q200 (passive components), and JEDEC JESD22-A104E (temperature cycling). Humidity control adheres to ASTM E104-21 (standard practice for maintaining constant relative humidity) and supports GLP-compliant documentation when paired with validated software. Optional IEC 61000-4-21 compliant shielding kits are available for EMI-sensitive device under test (DUT) configurations.
Software & Data Management
The chamber ships with LabCompanion TestSuite™ v4.2—a Windows-based application supporting real-time monitoring, multi-channel data logging (≥10 Hz sampling), and automated report generation (PDF/CSV/XLSX). All test logs include timestamped metadata, operator ID, calibration certificate references, and digital signatures compliant with FDA 21 CFR Part 11 Annex 11 requirements. Audit trails record all parameter modifications, user logins, and system events with immutable timestamps. Remote access is enabled via TLS 1.2-secured HTTPS, supporting role-based permissions (admin, technician, reviewer) and scheduled firmware updates with SHA-256 integrity verification.
Applications
- Automotive electronics: thermal cycling of ADAS ECUs, battery management systems (BMS), and infotainment modules per ISO 16750-4 and LV-124.
- Semiconductor packaging: preconditioning of QFN, BGA, and SiP assemblies prior to reflow or reliability stress screening (JESD22-A104, A110).
- Medical device validation: environmental aging of Class II/III devices under IEC 60601-1 Clause 10.2.1 (environmental testing requirements).
- Renewable energy: humidity freeze testing of PV inverters and charge controllers per UL 1741 SB and IEC 62109-2.
- Academic research: controlled exposure studies for polymer degradation kinetics, hygroscopic material swelling behavior, and corrosion initiation modeling.
FAQ
What is the typical stabilization time after a rapid temperature transition?
Stabilization to ±2.0 °C and ±2.0% RH is achieved within ≤15 minutes following a 100 °C step change (e.g., –40 °C → +60 °C), assuming no internal heat load exceeding 300 W.
Can the chamber be validated for IQ/OQ/PQ protocols?
Yes—LabCompanion provides GMP-compliant qualification packages including sensor mapping templates, uncertainty budgets per ISO/IEC 17025, and electronic records compatible with Veeva Vault or TrackWise LIMS.
Is nitrogen purge functionality available as an option?
Optional inert gas purge (N₂ or dry air) with mass flow controller and O₂ sensor is supported for oxygen-sensitive materials and low-humidity (<10% RH) extended dwell cycles.
How often does the humidity sensor require recalibration?
Capacitive RH sensors are factory-calibrated against NIST-traceable standards; annual recalibration is recommended, with built-in zero-point verification using saturated salt solutions (LiCl, MgCl₂, NaCl) at user-defined intervals.
Does the system support third-party SCADA integration?
Yes—Modbus TCP, OPC UA, and RESTful API endpoints are available for seamless integration with Siemens Desigo CC, Honeywell Experion PKS, or custom Python-based test orchestration frameworks.
