Overview
The Macono GDJS-100 High-Low Temperature and Humidity Cycling Environmental Test Chamber is a precision-engineered climatic simulation system designed to replicate dynamic environmental stress conditions for reliability validation of industrial components, electronic assemblies, automotive parts, and materials under controlled thermal and hygrothermal cycling. It operates on the principle of balanced heating–cooling–humidification control, enabling stable and reproducible generation of combined temperature and relative humidity profiles across wide operational ranges. The chamber complies with key international and national environmental testing standards—including IEC 60068-2-1 (Cold), IEC 60068-2-2 (Dry Heat), IEC 60068-2-30 (Damp Heat, Cyclic), and Chinese GB/T 2423.1–4 series—ensuring data integrity for qualification testing in R&D, QC, and certification workflows. Its robust architecture supports both steady-state and programmable cyclic test profiles, making it suitable for accelerated life testing, HALT pre-screening support, and compliance verification per ISO/IEC 17025-accredited laboratories.
Key Features
- Wide operational range: selectable temperature span from –20 °C to 150 °C (standard configurations include –40 °C, –60 °C, and –70 °C low-temperature options) and humidity control from 30 %RH to 98 %RH
- Precision climate control via balanced heating–cooling–humidification system, eliminating overshoot and ensuring stable setpoint attainment
- Stainless steel interior chamber (SUS304) with A3 steel exterior powder-coated enclosure for corrosion resistance and structural rigidity
- High-sealing silicone door gasket rated for continuous operation across –70 °C to +150 °C, minimizing leakage and improving energy efficiency
- Shallow-tray surface evaporation humidification system for rapid RH response and uniform moisture distribution
- Imported OYO 8226 large-format touchscreen controller with graphical programming interface, supporting up to 100 segments, 99 cycles, and real-time curve monitoring
- Integrated safety protections: over-temperature cutoff, compressor high-pressure shutdown, water shortage alarm, ground-fault circuit interruption, and fast-acting fuse protection
- Standard accessories include dual-view observation window (250 × 300 mm), 50 mm diameter test port, two adjustable stainless steel sample shelves, and LED interior lighting
Sample Compatibility & Compliance
The GDJS-100 accommodates diverse sample geometries and mass loads within its 1000 × 1000 × 1000 mm internal workspace (1 m³ volume), supporting full-size PCBs, enclosures, battery modules, and automotive ECUs. Air circulation employs a long-shaft, low-noise centrifugal fan with stainless steel blades and optimized duct design to maintain ≤ ±2 °C temperature uniformity and ≤ ±0.5 °C temperature stability per IEC 60068-3-5. Humidity deviation remains within +2 / –3 %RH across the operating range, verified per GB/T 10586–2018 and ASTM E1823–22 Annex A3. The system meets electromagnetic compatibility (EMC) requirements per EN 61326-1 and electrical safety per GB 4793.1–2007 (equivalent to IEC 61010-1). Documentation includes factory calibration reports traceable to CNAS-accredited standards, supporting GLP/GMP audit readiness.
Software & Data Management
The OYO 8226 controller provides embedded data logging with timestamped storage of temperature, humidity, and alarm events on internal memory (≥ 30 days at 1-minute intervals). Optional USB export enables CSV-formatted data transfer for post-processing in MATLAB, Python, or statistical analysis platforms. Remote monitoring and parameter adjustment are supported via optional RS-485 Modbus RTU or Ethernet TCP/IP interfaces, compatible with SCADA systems and centralized lab management software. Audit trail functionality records all user actions—including profile edits, start/stop commands, and manual overrides—with time stamps and operator IDs, fulfilling FDA 21 CFR Part 11 requirements when paired with user authentication add-ons. Firmware updates are performed via secure SD card loading, preserving configuration integrity.
Applications
This chamber is routinely deployed in: accelerated aging studies of polymer seals and conformal coatings; thermal shock preconditioning prior to vibration testing; condensation resistance validation for outdoor-rated electronics; humidity-induced corrosion screening of metal contacts and solder joints; qualification of lithium-ion battery packs under combined thermal–hygric stress; and environmental stress screening (ESS) of avionics subassemblies per MIL-STD-810H Method 507.5. It serves as a core tool for ISO 9001-certified manufacturing QA labs, third-party test houses accredited to CNAS (China National Accreditation Service), and university research groups conducting material degradation kinetics under cyclic climatic loading.
FAQ
What temperature and humidity ranges does the GDJS-100 support?
The standard configuration offers –20 °C to 150 °C temperature range and 30–98 %RH humidity control. Low-temperature variants down to –70 °C are available upon specification.
Is the controller compliant with FDA 21 CFR Part 11 for electronic records?
Yes—the OYO 8226 controller supports optional user-level access control, electronic signatures, and full audit trail logging when configured with password-protected administrator mode and external authentication integration.
Can custom test profiles be programmed and saved?
Yes. Up to 100 programmable segments per profile, with ramp rate control, dwell time, and cycle repetition settings—all storable in non-volatile memory.
What refrigeration system is used for sub-zero operation?
Models with –40 °C or lower capability employ cascade (two-stage) refrigeration using environmentally compliant R404A/R23 mixed refrigerants and imported Tecumseh or Copeland compressors.
Does the chamber include calibration documentation?
Each unit ships with a factory calibration certificate (traceable to national metrology institutes) covering temperature and humidity sensors at three points across the operational range, in accordance with ISO/IEC 17025 Clause 6.5.
