Overview
The Environmental Test Chamber – Temperature and Humidity Controlled Chamber is an ISO/IEC 17025-aligned stability testing platform engineered for rigorous evaluation of material behavior under precisely defined climatic conditions. Utilizing dual-stage mechanical refrigeration, PID-controlled resistive heating, and steam-based humidification, the chamber maintains stable thermal-hygrometric profiles across wide operational ranges (−65 °C to +150 °C; 20–95 % RH). Its design complies with fundamental metrological requirements specified in GB/T 5170.2–5–6 (equivalent to IEC 60068-3 series), ensuring traceable performance validation for laboratories operating under GLP, GMP, or ISO 9001 quality systems. The chamber’s closed-loop architecture—featuring high-efficiency centrifugal circulation, low-noise compressors, and vibration-dampened mounting—enables uninterrupted long-term testing of electronic components, polymer specimens, pharmaceutical packaging, and aerospace materials without ambient interference.
Key Features
- Mirror-finish SUS304 stainless steel interior chamber (corrosion-resistant, non-outgassing, easy to clean and validate)
- Exterior construction from CNC-machined A3 steel with electrostatic powder coating or optional brushed SUS304 for enhanced durability and cleanroom compatibility
- 100 mm thick composite insulation comprising high-density fiberglass and rigid polyurethane foam for minimal thermal bridging and energy efficiency
- Multi-layer tempered observation window with integrated conductive film heating and Philips LED backlighting for real-time, fog-free visual monitoring
- Dual-stage refrigeration system using certified hermetic compressors (Tecumseh or Embraco) and environmentally compliant refrigerants (R404A/R23)
- Load-capable electrical feedthroughs (optional) enabling powered-in situ testing of active devices under environmental stress
- Intelligent controller with 7-inch LCD touchscreen interface supporting bilingual (English/Chinese) operation, multi-segment programmable profiles, and real-time curve plotting of setpoint vs. actual values
- Comprehensive safety architecture including over-temperature, over-humidity, compressor high-pressure, phase failure, and door-open interlocks
Sample Compatibility & Compliance
This chamber accommodates standard test specimens up to 1000 L internal volume (custom sizes available), with full compatibility for PCB assemblies, lithium-ion battery cells, optical lenses, adhesives, and sterile medical device packaging. It satisfies mandatory calibration and verification protocols per GB/T 5170.2 (cold testing), GB/T 5170.3 (dry heat), GB/T 2423.3 (steady-state damp heat), and GB/T 2423.4 (cyclic damp heat)—all technically harmonized with IEC 60068-2-1, -2-2, -2-3, and -2-30. For regulated industries, the control system supports audit-ready data logging (time-stamped, user-ID tagged) and can be configured for FDA 21 CFR Part 11 compliance when paired with validated software packages and electronic signature modules.
Software & Data Management
The embedded controller records temperature and humidity data at user-selectable intervals (1–60 seconds), storing up to 100 test programs and 30 days of continuous measurement history onboard. Export is supported via USB 2.0 to CSV or Excel-compatible formats. Optional PC-based software enables remote supervision, alarm escalation via email/SMS, statistical process control (SPC) charting, and automated report generation aligned with ISO/IEC 17025 clause 7.8. All logged data include metadata: operator ID, calibration certificate numbers, sensor serial IDs, and environmental ambient reference values—ensuring full traceability during regulatory audits.

FAQ
What standards does this chamber comply with for calibration and verification?
It meets GB/T 5170.2–6 (equivalent to IEC 60068-3-1 to -3-6), supporting third-party calibration against NIST-traceable references. Full validation documentation (IQ/OQ/PQ templates) is provided upon request.
Can the chamber operate continuously for 1,000+ hours without maintenance?
Yes—designed for unattended operation with predictive maintenance alerts; compressor oil life exceeds 12,000 hours under nominal load per manufacturer specifications.
Is remote monitoring and control supported?
Standard Ethernet port enables integration into LabView, SCADA, or custom MES platforms via Modbus TCP/IP or OPC UA protocols.
What is the typical lead time for delivery and installation support?
Production lead time is 8–10 weeks after order confirmation; on-site commissioning and operator training are included in the scope of supply for all international orders.
Does the controller support multi-step ramp-soak-hold profiles with humidity coupling?
Yes—the touch interface allows up to 99 segments per program, with independent or synchronized temperature/humidity ramps and dwell times, including rate-limited transitions per IEC 60068-2-14.
