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

Overview

The Jianhu JH-THC Series is an engineered environmental test chamber designed for precise, reproducible simulation of temperature and humidity conditions in R&D laboratories, quality control facilities, and reliability testing centers. Based on the fundamental principles of psychrometric control and forced-air convection thermodynamics, the system maintains stable thermal-hygrometric profiles across its operational range—enabling standardized evaluation of material stability, coating integrity, electronic component performance, and packaging barrier properties under controlled ambient stressors. Unlike generic benchtop units, the JH-THC Series integrates dual-loop PID control architecture with independent temperature and humidity regulation channels, minimizing cross-coupling effects during dynamic cycling protocols. Its air-cooled refrigeration system ensures rapid thermal response without requiring external water infrastructure—making it suitable for cleanroom-adjacent installations and space-constrained lab environments.

Key Features

• Modular chamber architecture supporting fully customizable interior dimensions—from compact 30 L benchtop units to large-volume 1,000+ L walk-in configurations.
• Dual independent PID controllers for temperature and relative humidity, each with real-time deviation monitoring and auto-tuning capability.
• High-efficiency centrifugal circulation fan with laminar airflow design, ensuring uniform distribution (≤ ±2 °C / ≤ ±3 % RH) per IEC 60068-3-5 and GB/T 2423.3 standards.
• Corrosion-resistant stainless-steel interior (SUS304) and insulated double-wall construction with polyurethane foam (≥ 100 mm thickness) for thermal retention.
• Programmable multi-step test cycles—including ramp-soak-hold sequences—with up to 100 segments and 999 cycles per program.
• Integrated safety interlocks: over-temperature cut-off, humidity sensor failure alarm, door-open detection, and refrigerant pressure monitoring.

Sample Compatibility & Compliance

The JH-THC Series accommodates diverse sample geometries and material classes—including polymer films, lithium-ion battery cells, PCB assemblies, pharmaceutical blister packs, and aerospace composite coupons—without requiring auxiliary fixtures. Chamber interiors are compatible with non-reactive sample trays, hanging racks, and custom mounting brackets (available upon request). All models comply with ISO/IEC 17025 calibration traceability requirements when paired with certified reference sensors. The system supports audit-ready operation under GLP and GMP frameworks via optional data logging with time-stamped event records, user access logs, and electronic signature functionality aligned with FDA 21 CFR Part 11 Annex 11 expectations. It meets essential clauses of ASTM D4332 (conditioning containers), IEC 60068-2-30 (damp heat cyclic), and GB/T 10586 (environmental test chambers).

Software & Data Management

Jianhu’s proprietary TH-Control Suite v4.2 provides intuitive Windows-based interface for test configuration, real-time parameter visualization, and post-test analysis. The software supports CSV export of time-series temperature/humidity datasets at configurable sampling intervals (1–60 seconds), enabling integration with third-party statistical process control (SPC) platforms such as JMP or Minitab. Optional cloud-enabled firmware allows remote monitoring via secure HTTPS API endpoints—facilitating centralized fleet management across multi-site laboratories. Audit trails include operator ID, parameter changes, alarm events, and calibration history—all retained for ≥18 months per internal QA policy. Raw data files are stored in encrypted binary format with SHA-256 checksum validation to ensure integrity during archival or transfer.

Applications

• Accelerated aging studies of polymer electrolytes and separator membranes for next-generation batteries.
• Stability assessment of moisture-sensitive APIs and lyophilized biologics per ICH Q1A(R2) guidelines.
• Environmental preconditioning of automotive ECUs prior to ESD and vibration qualification (ISO 16750-4).
• Validation of protective coatings on aerospace aluminum alloys exposed to tropical climatic profiles (MIL-STD-810H Method 507.6).
• Qualification testing of flexible OLED displays under combined thermal-hygrometric stress (JEDEC JESD22-A110).
• Calibration verification of handheld hygrometers and thermocouple arrays using NIST-traceable reference probes.

FAQ

Can the JH-THC Series perform temperature-humidity cycling per IEC 60068-2-30?
Yes—programmable ramp rates (1.0–3.0 °C/min), dwell times, and humidity transitions are fully configurable to meet Clause 6.2 of IEC 60068-2-30.
Is third-party calibration certification available?
Yes—Jianhu partners with CNAS-accredited labs to provide on-site or depot-based calibration with ISO/IEC 17025-compliant certificates, including uncertainty budgets.
What maintenance intervals are recommended for long-term reliability?
Comprehensive preventive maintenance is advised every 12 months, including refrigerant pressure verification, sensor recalibration, condensate drain inspection, and fan bearing lubrication.
Does the system support integration into existing MES or LIMS environments?
Yes—OPC UA and Modbus TCP protocols are supported via optional communication modules; custom RESTful API wrappers can be developed for enterprise system interoperability.
Are custom interior configurations (e.g., wire ports, viewing windows, load ports) available?
Yes—Jianhu’s engineering team provides mechanical drawings and performs structural FEA analysis for all non-standard modifications prior to fabrication.
