Jianhu JH-THC Series Precision Temperature and Humidity Controlled Environmental Test Chamber

Overview

The Jianhu JH-THC Series Precision Temperature and Humidity Controlled Environmental Test Chamber is engineered for long-term, high-fidelity simulation of controlled climatic conditions in R&D laboratories, quality assurance departments, and third-party testing facilities. Operating on the principle of closed-loop refrigeration combined with precision steam humidification and PID-based adaptive control, this chamber delivers stable, repeatable thermal-hygrometric environments essential for reliability validation, accelerated aging, environmental stress screening (ESS), and compliance testing per international standards including IEC 60068-2, GB/T 2423, MIL-STD-810, and ISO 16750. Designed for continuous operation over extended cycles—up to thousands of hours—the system integrates robust mechanical architecture with thermodynamic optimization to ensure minimal drift, low maintenance burden, and operational continuity critical in battery cycling, automotive electronics qualification, and material science applications.

Key Features

• Adaptive Fuzzy-PID Control Algorithm: Dynamically adjusts heating/cooling output and humidification rate to maintain setpoint stability under variable load conditions—including high-thermal-mass samples such as EV battery modules or embedded PCB assemblies.
• Air-Cooled Refrigeration System: Utilizes high-efficiency scroll compressors sourced from Tier-1 global suppliers, matched with optimized condenser airflow design to ensure consistent performance across ambient temperatures up to 35°C without derating.
• Corrosion-Resistant Stainless Steel Interior: 304-grade inner chamber walls and insulated double-wall construction with polyurethane foam (≥100 mm thickness, λ ≤ 0.022 W/m·K) minimize thermal bridging and condensation leakage during high-humidity operation.
• Customizable Chamber Geometry: Supports non-standard internal dimensions and door configurations (e.g., large access hatches, top-loading designs) to accommodate oversized test specimens such as rail components, photovoltaic panels, or medical device enclosures.
• Redundant Sensor Architecture: Dual platinum resistance thermometers (PT100) and capacitive humidity sensors with real-time cross-validation reduce measurement uncertainty and support GLP-compliant data integrity.

Sample Compatibility & Compliance

The JH-THC Series accommodates a broad spectrum of sample types—from passive electronic components and polymer films to active systems like Li-ion battery packs undergoing charge/discharge thermal profiling. Its uniformity profile (±1°C / ±3% RH) meets Class II requirements per IEC 60068-3-5 for climatic testing equipment. All units are manufactured under an ISO 9001-certified quality management system and undergo mandatory 120-hour endurance verification prior to shipment, simulating worst-case operational loads at 40°C / 95% RH. Documentation includes factory calibration certificates traceable to NIM (National Institute of Metrology, China), and optional UKAS-accredited calibration services are available upon request. The chamber supports audit-ready operation compliant with FDA 21 CFR Part 11 when paired with Jianhu’s validated data acquisition software.

Software & Data Management

Jianhu’s proprietary THControl v4.2 software provides full remote monitoring, programmable multi-step profiles (up to 99 segments), real-time trend visualization, and automated report generation in PDF/CSV formats. The system logs all parameter changes, alarm events, and sensor readings with timestamped metadata, enabling full traceability required under GLP and GMP frameworks. Optional features include role-based user access control, electronic signature capability, and integration with LIMS platforms via OPC UA or Modbus TCP. Software validation packages—including IQ/OQ documentation and test scripts—are provided for regulated industries.

Applications

• Automotive Electronics: Thermal-hygric preconditioning of ADAS ECUs, infotainment modules, and powertrain controllers per ISO 16750-4.
• Energy Storage Systems: Cycle-life evaluation of lithium-ion cells and modules under dynamic temperature/humidity profiles mimicking real-world storage and operational environments.
• Academic Research: Controlled environmental exposure for polymer degradation studies, biodegradable packaging development, and atmospheric corrosion modeling.
• Medical Device Validation: Accelerated shelf-life testing of sterile packaging per ASTM F1980 and ISO 11607.
• Electronics Manufacturing: Moisture sensitivity level (MSL) testing per JEDEC J-STD-020 and post-reflow moisture soak protocols.

FAQ

What is the typical lead time for custom-sized chambers?
Standard configurations ship within 15–25 working days; non-standard dimensions and integrated options (e.g., internal lighting, viewing windows, or electrical feedthroughs) extend lead time to 35–50 days depending on complexity.

Does the chamber support automated data export to enterprise systems?
Yes—THControl v4.2 supports scheduled CSV exports, REST API endpoints, and native OPC UA server functionality for seamless integration with MES, SCADA, or cloud-based analytics platforms.

Can the system be validated for ISO/IEC 17025 laboratory accreditation?
Each unit ships with a full factory calibration certificate. Jianhu provides on-site IQ/OQ/ PQ support, including protocol development, execution, and final documentation aligned with ILAC-G8 and CNAS requirements.

Is preventive maintenance included in the warranty?
The standard 36-month warranty covers parts and labor for core subsystems (refrigeration, humidification, control electronics). Preventive maintenance visits are offered annually under separate service agreements, including sensor recalibration, refrigerant pressure verification, and insulation integrity checks.
