Overview
The Macono GDJS-025 High-Low Temperature and Humidity Cycling Environmental Test Chamber is a precision-engineered climatic simulation system designed for reliability validation of industrial components, electronic assemblies, automotive parts, and packaging materials under dynamically varying thermal and hygrothermal stress conditions. It operates on the principle of balanced heating–cooling–humidification control, enabling stable and repeatable generation of programmable temperature-humidity profiles across wide operational ranges. The chamber meets the core technical requirements defined in GB/T 2423.1 (Cold Test), GB/T 2423.2 (Dry Heat Test), GB/T 2423.3 (Constant Damp Heat), and GB/T 2423.4 (Cyclic Damp Heat), as well as structural and performance specifications outlined in GB/T 10592 (High-Low Temperature Test Chambers) and GB/T 10586 (Damp Heat Test Chambers). Its architecture supports both standard compliance testing and custom environmental stress screening protocols aligned with international product qualification frameworks.
Key Features
- Stainless steel interior chamber (SUS304) and A3 steel exterior with electrostatic powder coating for corrosion resistance and mechanical durability
- High-performance silicone rubber door gasket rated for continuous operation from –70 °C to +150 °C, ensuring leak-tight sealing under thermal cycling
- Intelligent balanced conditioning system: simultaneous proportional control of refrigeration, electric heating, and surface-evaporation humidification to achieve precise setpoint tracking
- Wide-range programmable operation: selectable temperature spans from –20 °C to +150 °C (with optional –40 °C, –60 °C, or –70 °C low-temperature configurations) and humidity control from 30 %RH to 98 %RH
- Temperature uniformity ≤ ±2 °C; temperature fluctuation ≤ ±0.5 °C; humidity deviation ≤ +2 / –3 %RH (measured at chamber center per IEC 60068-3-5)
- Integrated 7-inch full-color LCD touchscreen controller (OYO brand, Japan) with intuitive menu-driven interface, multi-segment curve programming, and data logging capability
- Standard safety protections: over-temperature cutoff, compressor high-pressure protection, water shortage alarm, leakage current interruption, and fast-blow fuse circuitry
Sample Compatibility & Compliance
The GDJS-025 accommodates samples up to 500 mm × 650 mm × 700 mm (W×D×H) within its working volume. Its design supports mounting fixtures, cable feedthroughs (Φ50 mm test port), dual sample racks, and internal LED lighting with tempered double-glazed observation window (250 mm × 300 mm). The chamber is routinely deployed in laboratories conducting environmental qualification per ISO 16750-4 (road vehicles), IEC 60068-2 series (environmental testing), MIL-STD-810G Method 502.6/507.6 (temperature/humidity cycling), and automotive OEM-specific standards (e.g., GMW15000, Ford CETP). All control firmware and sensor calibration traceability align with GLP-compliant documentation practices. While not inherently 21 CFR Part 11 compliant, the system supports audit-ready data export (CSV, USB) for integration into validated quality management systems.
Software & Data Management
The OYO touchscreen controller provides real-time display of chamber status, setpoints, actual values, and alarm history. Users can define up to 120 programmable segments across multiple cycles, store ≥100 test profiles, and enable automatic curve saving upon completion. Logged data includes timestamped temperature/humidity readings at 1-minute intervals, with export via USB flash drive. Optional RS485/Modbus RTU interface enables integration with centralized lab monitoring platforms (e.g., LabVIEW, SCADA). Firmware supports password-protected parameter modification, user-level access control (operator/engineer/administrator), and event-triggered data capture for non-conformance investigations.
Applications
This chamber serves critical roles in R&D validation, incoming QC, and production lot release testing. Typical use cases include: accelerated aging of polymer seals and adhesives; thermal shock evaluation of PCBAs prior to conformal coating; moisture ingress assessment of hermetic enclosures; verification of battery module thermal management under combined hot/humid conditions; and shelf-life prediction of pharmaceutical packaging under ICH Q1A(R2) stability protocols. Its reproducible cycling performance makes it suitable for HALT/HASS pre-screening when configured with rapid ramp rates (≥2 °C/min heating, ≤1 °C/min cooling).
FAQ
What temperature and humidity ranges are supported by the GDJS-025?
Standard configuration covers –20 °C to +100 °C with 30–98 %RH; optional low-temperature variants extend down to –70 °C, and high-temperature versions reach +150 °C.
Is the chamber suitable for regulatory submission testing?
Yes—its adherence to GB/T 2423 and GB/T 10592 enables use in domestic certification workflows; for FDA or EU MDR submissions, users must validate the system per IQ/OQ/PQ protocols and maintain full calibration records.
Can custom test profiles be uploaded remotely?
No native Ethernet or cloud connectivity is provided; however, profiles may be pre-loaded via USB before test initiation, and post-test data extraction is fully supported.
What maintenance is required for long-term reliability?
Quarterly inspection of condensate drain lines, annual replacement of humidifier water tray seals, biannual verification of PT100 sensor accuracy against NIST-traceable references, and routine cleaning of evaporator fins per manufacturer guidelines.
Does the system include validation documentation?
Factory-assembled units ship with a Certificate of Conformance and basic calibration report; full IQ/OQ documentation packages and third-party validation support are available as add-on services.
