Overview
The Jianhu JH-THC Series Intelligent Temperature & Humidity Environmental Test Chamber is an engineered solution for accelerated aging validation under controlled thermo-hygrometric stress conditions. Designed in accordance with the physical principles of coupled thermal-moisture diffusion and material degradation kinetics, it enables precise simulation of real-world environmental exposure profiles—particularly those relevant to lithium-ion battery systems and consumer electronic assemblies. The chamber operates on a dual-loop PID adaptive control architecture, integrating independent high-stability refrigeration (hermetic scroll compressor), electric heating, and steam-based humidification subsystems. Its core function is to replicate time-accelerated degradation mechanisms—including electrolyte hydrolysis, polymer sealant swelling, printed circuit board (PCB) dendritic corrosion, and interfacial delamination—under programmable temperature/humidity trajectories compliant with international reliability test standards.
Key Features
- Explosion-proof certified chamber construction (ATEX/IECEx-compliant enclosure options available), meeting Class II, Division 1 hazardous area requirements for battery cell and module testing.
- Wide operational envelope: -70°C to +150°C temperature range with humidity control from 20% to 98% RH at temperatures ≥10°C; humidity accuracy maintained at ±2% RH, temperature stability at ±0.3°C under steady-state conditions.
- Multi-segment programmable cycling capability supporting up to 999 steps per profile, enabling complex sequences such as “45°C / 85% RH → 25°C / 50% RH → -20°C / 30% RH” to emulate seasonal or operational duty cycles.
- High-resolution 10.1-inch capacitive touchscreen HMI with embedded data logging (≥100,000 data points), real-time curve visualization, and USB export functionality.
- Reinforced stainless-steel inner chamber (SUS304), double-wall vacuum-insulated door, and condensate management system ensuring long-term operational integrity during extended high-humidity runs.
- Integrated safety interlocks including over-temperature cut-off, humidity sensor self-diagnostic, refrigerant pressure monitoring, and emergency power-off circuitry.
Sample Compatibility & Compliance
The JH-THC Series accommodates battery packs (up to 150 kg load capacity), EV traction modules, portable electronics (smartphones, wearables, IoT edge devices), and PCB subassemblies. Chamber interior dimensions are fully customizable—from standard 400 × 400 × 400 mm³ to large-volume configurations exceeding 2000 L—to support full-system validation per GB/T 31485-2015 (Electric Vehicle Traction Batteries), IEC 62133-2 (Secondary Cells for Portable Applications), and JEDEC JESD22-A101 (Steady-State Moisture Reflow Sensitivity). All units undergo factory calibration traceable to NIM (National Institute of Metrology, China) and support optional ISO/IEC 17025-compliant calibration documentation. The system architecture complies with GLP/GMP audit readiness requirements, including user access control, electronic signature capability, and FDA 21 CFR Part 11–compatible audit trail generation when paired with optional Jianhu LabSuite™ software.
Software & Data Management
Jianhu LabSuite™ (v3.2+) provides centralized test orchestration, remote monitoring via Ethernet/Wi-Fi, and automated report generation in PDF/CSV/XLSX formats. It supports multi-chamber synchronization, statistical process control (SPC) charting, and deviation alerting based on configurable thresholds. Raw sensor data (temperature, humidity, chamber pressure, power consumption) is timestamped with microsecond resolution and stored locally on industrial-grade SSD. Data export protocols include Modbus TCP, OPC UA, and RESTful API integration for MES/PLM interoperability. All firmware updates are digitally signed and verified; historical configuration versions are retained for full traceability across product lifecycle stages.
Applications

- Consumer Electronics Qualification: IPC-J-STD-006B-compliant moisture sensitivity level (MSL) screening, conformal coating adhesion validation, and MEMS microphone diaphragm hysteresis assessment under 38°C/90% RH sweat-simulating conditions.
- Automotive Electronics: AEC-Q200 stress screening of ADAS ECUs, infotainment displays, and charging port connectors subjected to ISO 16750-4 (Climate Load) profiles.
- Material Science Research: Polymer hygrothermal aging studies (e.g., PA6, PBT, epoxy encapsulants) tracking dimensional change, tensile strength loss, and water absorption kinetics per ASTM D570.
FAQ
Does the chamber support continuous operation at 85% RH above 60°C?
Yes—equipped with high-efficiency steam generator and anti-condensation air curtain, the JH-THC maintains stable humidity up to 98% RH at 85°C for durations exceeding 1,000 hours.
Can test profiles be imported from external sources (e.g., MATLAB, Excel)?
Yes—LabSuite™ accepts CSV-formatted time-step profiles with columns for setpoint temperature, humidity, and dwell time; interpolation algorithms ensure smooth transitions between segments.
Is third-party calibration certification included with delivery?
Factory calibration certificate (NIM-traceable) is standard; ISO/IEC 17025-accredited calibration reports are available as an optional service with on-site verification.
What safety certifications does the explosion-proof variant hold?
The Ex d IIB T4 Gb-rated version complies with GB 3836.1–2010 and IEC 60079-0:2017; ATEX Directive 2014/34/EU certification is available upon request.
How is data integrity ensured during power interruption?
All active test sessions auto-save to non-volatile memory every 5 seconds; upon recovery, the system resumes from the last validated checkpoint without data loss.
