Overview
The GDW-3012 Environmental Test Chamber is a precision-engineered temperature and humidity controlled chamber designed for accelerated environmental stress testing of materials, components, and finished products under reproducible laboratory conditions. It operates on the principle of forced-air convection with dual independent control loops—PID-regulated refrigeration and heating systems coupled with a steam-based humidification module—to maintain stable thermal and hygrothermal profiles across its working volume. The chamber supports standardized test protocols per IEC 60068-2, MIL-STD-810H, GB/T 2423, and ISO 16750-4, enabling validation of product robustness against thermal cycling, cold storage, high-temperature aging, and combined temperature-humidity exposure.
Key Features
- Wide operational range: –40 °C to +150 °C temperature control, with programmable humidity from 30 % RH to 98 % RH (non-condensing at low temperatures)
- Digital PID controller with 0.1 °C display resolution and real-time deviation compensation, delivering typical temperature stability better than ±0.5 °C at setpoint
- Uniform internal airflow architecture using a 180 W axial fan ensures temperature gradient ≤2 °C across the test zone (verified by NIST-traceable sensor mapping)
- Integrated safety system includes over-temperature, under-temperature, over-pressure, and door-open alarms with audible/visual alerts compliant with EN 61000-6-2 EMC requirements
- Customizable configuration options: extended low-temperature capability (–70 °C), stainless steel interior, data logging interface (RS485/Modbus RTU), and optional Ethernet connectivity for remote monitoring
- AC12 V low-voltage interior lighting provides safe, non-heat-generating illumination for visual inspection during active tests
Sample Compatibility & Compliance
The GDW-3012 accommodates samples up to 600 mm × 500 mm × 500 mm (W×D×H) with standard access ports (Ø50 mm, two units) for external cabling or sensor feedthrough. Its chamber construction uses 1.2 mm SUS304 stainless steel inner walls and high-density polyurethane insulation (≥100 mm thickness) to minimize thermal leakage and support long-duration stability testing. The unit meets CE marking requirements and conforms to GLP-compliant operation when used with validated calibration procedures. All temperature and humidity sensors are calibrated in accordance with ISO/IEC 17025-accredited traceability chains, supporting audit readiness for ISO 9001, IATF 16949, and FDA-regulated environments where environmental qualification records are required.
Software & Data Management
The embedded controller supports up to 100 programmable test profiles, each with up to 99 segments (ramp/soak/humidity coupling). Optional PC-based software (Windows-compatible, USB or RS485 interface) enables full test sequencing, real-time graphing, alarm history export (CSV), and electronic signature functionality aligned with 21 CFR Part 11 Annex 11 requirements. Audit trail logs record operator ID, parameter changes, start/stop timestamps, and calibration events—retained for ≥36 months. Data integrity is preserved via write-protected memory and automatic backup upon power interruption.
Applications
- Electronics reliability: Thermal cycling of PCBAs, connectors, and semiconductor packages per JEDEC JESD22-A104

- Pharmaceutical packaging: Accelerated stability studies of blister packs and vials per ICH Q1A(R2)
- Material science: Dimensional stability assessment of polymers, composites, and adhesives across hygrothermal gradients
- Quality assurance labs: In-process verification of solder paste storage conditions, optical lens coatings, and elastomer compression set
FAQ
What is the standard calibration interval recommended for the GDW-3012?
Annual calibration is advised; however, users operating under ISO/IEC 17025 or GMP must define intervals based on risk assessment, usage frequency, and historical performance data.
Can the GDW-3012 perform rapid temperature transitions (e.g., 10 °C/min)?
Standard configuration supports ramp rates up to 3 °C/min; high-speed variants with enhanced compressor capacity and pre-cooled air ducts are available upon request.
Is humidity control available below 0 °C?
Humidity is not actively maintained below 0 °C due to condensation and ice formation risks; however, relative humidity values can be displayed as calculated dew point equivalents for dry-cold profiling.
Does the chamber support third-party data acquisition systems?
Yes—via Modbus RTU over RS485, the GDW-3012 exposes real-time temperature, humidity, alarm status, and setpoint data for integration into LabVIEW, SCADA, or MES platforms.
What documentation is supplied with delivery?
Factory calibration report, CE declaration of conformity, operation manual (English), maintenance logbook, and IQ/OQ templates compliant with ASTM E2500-13 are included.
