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

Overview

The Jianhu JH-THC Series Temperature and Humidity Controlled Environmental Test Chamber is an engineered solution for precise, reproducible simulation of ambient climatic conditions in laboratory and industrial R&D settings. Designed around a dual-loop PID-controlled heating/humidification system and water-cooled refrigeration circuit, the chamber operates on fundamental thermodynamic principles to maintain stable setpoints across defined temperature (15–45 °C) and relative humidity (30–98 % RH) ranges. Unlike static environmental simulators, the JH-THC series integrates real-time feedback from calibrated platinum resistance thermometers (PT100) and capacitive humidity sensors, enabling dynamic compensation for thermal mass loading, door opening events, and ambient facility fluctuations. Its vertical upright architecture optimizes floor space utilization while supporting modular integration with auxiliary systems—such as salt mist nozzles or UV exposure modules—for multi-stress accelerated aging protocols. The chamber is not intended for thermal shock testing per se; however, its rapid heating rate (up to 3.0 °C/min) and tight control fidelity make it suitable as a foundational unit within broader reliability test sequences aligned with IEC 60068-2-1, -2-2, and -2-78.

Key Features

• Water-cooled condensing system ensures stable operation under continuous duty cycles and high ambient temperatures, minimizing compressor cycling and extending service life.
• Double-wall insulated stainless steel chamber construction with polyurethane foam (≥100 mm thickness) delivers low thermal leakage and high energy efficiency.
• Programmable 7-inch TFT touchscreen controller with built-in data logging (100,000-point capacity), USB export, and optional Ethernet connectivity for remote monitoring.
• Independent humidity generation via steam humidifier with deionized water feed path prevents mineral deposition and ensures long-term sensor accuracy.
• Full customization capability: internal dimensions, shelving configuration, port placements (electrical, pneumatic, optical), and material finishes (e.g., SUS304 vs. electropolished 316L) are configurable per client specifications.
• Compliance-ready design includes audit trail functionality, user-level access control (three-tier), and optional 21 CFR Part 11-compliant software packages for regulated industries.

Sample Compatibility & Compliance

The JH-THC chamber accommodates a broad spectrum of sample types—including polymer composites, printed circuit boards, pharmaceutical packaging, lithium-ion battery cells, and optical coatings—without requiring sample-specific fixtures. Internal volume scalability (from 50 L to 1,000 L standard; larger upon request) supports both single-component validation and full-assembly environmental stress screening. All units conform to GB/T 10586–2018 (Chinese national standard for environmental test chambers), and design documentation supports alignment with ISO/IEC 17025:2017 calibration traceability requirements. Optional factory calibration certificates are issued against NIST-traceable reference standards. For GMP/GLP environments, optional IQ/OQ documentation packages and installation qualification support are available upon order.

Software & Data Management

Jianhu’s proprietary JH-CloudLink software enables centralized management of multiple chambers across distributed lab sites. The platform provides real-time visualization of chamber status, deviation alerts (configurable thresholds for temp/RH excursions), and automated report generation in PDF or CSV formats. Raw logged data is stored in encrypted SQLite databases with timestamped metadata, including operator ID, parameter change history, and alarm event logs. For laboratories operating under FDA 21 CFR Part 11, optional software modules deliver electronic signatures, role-based permissions, and immutable audit trails—fully compliant with ALCOA+ data integrity principles. Integration with LIMS systems is supported via RESTful API or OPC UA protocol.

Applications

• Accelerated aging studies for automotive interior materials per SAE J2412 and ISO 11341.
• Stability testing of medical device packaging per ISO 11607-1 and ASTM F1980.
• Pre-conditioning of electronic assemblies prior to HALT/HASS per JEDEC JESD22-A110.
• Moisture absorption kinetics modeling for hygroscopic polymers used in aerospace components.
• Environmental stress screening of photovoltaic encapsulants under damp heat (IEC 61215-2 MQT 10.1).
• Validation of HVAC filter media performance under controlled humidity gradients.

FAQ

Is this chamber suitable for thermal shock testing?
No—the JH-THC series is optimized for steady-state temperature and humidity control, not rapid transition between extreme conditions. For thermal shock applications, Jianhu offers dedicated JH-TSC series two- or three-zone chambers with independent hot/cold reservoirs.
Can the chamber be integrated into an existing building management system (BMS)?
Yes—standard Modbus RTU over RS-485 is included; optional BACnet MS/TP or KNX interfaces are available for facility-wide integration.
What is the typical lead time for custom configurations?
Standard models ship within 15 working days; non-standard dimensions or special material requests require 25–35 working days depending on complexity and component availability.
Does Jianhu provide on-site installation and commissioning?
Yes—global technical support includes factory acceptance testing (FAT), site acceptance testing (SAT), and operator training. Installation services are available in APAC, EMEA, and North America through authorized partners.
Are calibration certificates included with shipment?
A factory calibration certificate (traceable to CNAS-accredited labs) is provided at no cost. Full ISO/IEC 17025-certified calibration with uncertainty statements is available as a value-added service.
