LabCompanion TH-800-15 Rapid Temperature and Humidity Cycling Chamber

Overview

The LabCompanion TH-800-15 Rapid Temperature and Humidity Cycling Chamber is an engineered environmental simulation system designed for accelerated reliability testing of materials, components, and electronic assemblies under dynamically controlled thermal and hygrothermal stress conditions. Based on forced-air convection with dual independent refrigeration and steam-based humidification systems, the chamber delivers precise, repeatable, and traceable control over temperature and relative humidity across a wide operational envelope. Its architecture supports both steady-state conditioning and programmable ramp-hold cycles—including rapid transitions between extreme cold and high-humidity states—enabling compliance-driven validation per IEC 60068-2-1, IEC 60068-2-2, IEC 60068-2-14, JESD22-A104, MIL-STD-810H Method 502.7, and GB/T 2423.1–2423.4 series standards. The chamber’s structural integrity, insulation performance, and sensor calibration traceability align with ISO/IEC 17025 requirements for accredited test laboratories.

Key Features

• High-performance dual-stage cascade refrigeration system enabling stable operation down to −70 °C without liquid nitrogen assistance
• Steam generator-based humidification with PID-controlled water level and anti-scaling design for long-term RH stability at 20–98 %RH
• Advanced 10.4-inch color touchscreen controller with built-in data logging (up to 10,000 segments), USB export, and Ethernet interface for remote monitoring
• Triple-layer insulated chamber walls (polyurethane foam + vacuum panel + aluminum foil barrier) minimizing thermal leakage and improving energy efficiency
• Independent temperature and humidity sensors (PT100 class A & capacitive RH transducers) with real-time auto-compensation and user-accessible calibration offset adjustment
• Programmable ramp rates from 1 to 25 °C/min, configurable as linear or non-linear profiles to emulate real-world thermal shock scenarios
• Internal chamber volume of 800 L (1000 × 1000 × 800 mm), optimized for large PCB assemblies, automotive ECUs, battery modules, and aerospace avionics enclosures

Sample Compatibility & Compliance

The TH-800-15 accommodates diverse sample geometries and thermal mass profiles, including stacked printed circuit board assemblies, sealed polymer housings, lithium-ion battery packs, and optoelectronic sensor modules. Its uniform airflow distribution—validated per ASTM E145 Annex A3—ensures spatial temperature deviation ≤ ±2.0 °C and humidity deviation ≤ ±3 %RH across the full working volume. All control algorithms and firmware comply with IEC 62443-4-2 for industrial cybersecurity baseline requirements. The system supports audit-ready documentation generation for GLP/GMP environments, including electronic signatures, change logs, and 21 CFR Part 11-compliant data integrity features when integrated with optional LabCompanion TestSuite software.

Software & Data Management

LabCompanion TestSuite (v4.2+) provides centralized test sequence management, multi-chamber synchronization, and automated report generation in PDF/CSV formats compliant with ISO/IEC 17025 Clause 7.8.2. Data acquisition records timestamped temperature, humidity, ramp rate, alarm status, and controller diagnostics at user-defined intervals (1 s to 60 min). Raw datasets are stored in encrypted SQLite format with SHA-256 hash verification; historical data can be exported via SFTP or OPC UA to MES/LIMS platforms such as Siemens Opcenter, Thermo Fisher SampleManager, or LabVantage. Firmware updates follow a signed binary verification protocol to prevent unauthorized modification.

Applications

• Accelerated life testing of automotive infotainment systems under combined thermal cycling and condensation exposure
• Qualification of medical device enclosures per ISO 14971 risk management and IEC 60601-1 environmental clauses
• PCB solder joint fatigue evaluation using JEDEC JESD22-A104D-defined temperature/humidity profiles
• Material compatibility assessment for conformal coatings, adhesives, and potting compounds exposed to cyclic dew point shifts
• Pre-conditioning of lithium-ion cells prior to safety testing (UN 38.3, UL 1642)
• Validation of optical sensor drift behavior under sustained high-RH and low-temperature storage conditions

FAQ

What is the maximum allowable sample mass for stable temperature ramping?
The chamber maintains specified ramp rates for loads up to 50 kg distributed evenly across the chamber floor; heavier or thermally dense samples require derating analysis based on specific heat capacity and surface area.
Does the system support custom profile import via CSV or Excel?
Yes—TestSuite accepts industry-standard CSV-formatted time-step profiles with columns for setpoint temperature, target RH, ramp rate, and dwell duration.
Is NIST-traceable calibration documentation available?
Factory calibration certificates (per ISO/IEC 17025) are provided with each unit; on-site calibration services with accredited third-party providers are available globally through LabCompanion’s service network.
Can the chamber operate continuously at 98% RH and +85°C?
Yes—the steam generator and condensate management system are rated for uninterrupted operation at this condition for ≥1,000 hours, subject to routine maintenance per the operator manual.
How is data integrity ensured during power interruption?
The controller retains all active program data and logged measurements in non-volatile memory; upon recovery, it resumes execution from the last validated segment with automatic timestamp reconciliation.
