Overview
The Combined Temperature-Humidity-Vibration Environmental Test Chamber is an integrated reliability validation platform engineered for simultaneous multi-stress exposure of engineering prototypes and production units. It applies controlled thermal cycling (−70 °C to +150 °C), humidity modulation (5–98% RH), and mechanical vibration (sine, random, swept-sine, programmable profiles) within a single sealed test volume—enabling accelerated life testing, HALT/HASS simulation, and structural integrity verification under real-world operational stressors. Unlike sequential chamber-based testing, this system eliminates thermal lag and mounting reconfiguration delays by maintaining full environmental continuity during dynamic excitation. Its architecture adheres to the physical coupling principles defined in IEC 60068-2-64 (vibration) and IEC 60068-2-30 (damp heat cyclic), ensuring traceable correlation between lab-generated stress spectra and field failure modes.
Key Features
- Monolithic stainless steel inner chamber constructed from mirror-finished SUS#304 grade steel, resistant to thermal fatigue, corrosion, and condensation-induced pitting.
- Double-sealed observation window with laminated tempered glass and conductive ITO film for EMI-shielded visual monitoring without thermal distortion.
- Modular vibration interface: precision-machined flange mount compatible with industry-standard shakers (e.g., LDS V875, TIRA TV 51120); includes multi-layer epoxy/silicone gasketing for hermetic thermal-vacuum integrity during operation.
- High-efficiency refrigeration system: single-stage compressor for −20 °C capability; dual-stage cascade configuration for extended low-temperature operation down to −70 °C; uses environmentally compliant R404A/R23 mixed-refrigerant circuitry.
- Intelligent controller with 10.4″ color TFT touchscreen, embedded real-time OS, and programmable test profiles supporting up to 100 segments, 999 cycles, and conditional branching logic.
- Integrated safety architecture: independent overtemperature/overhumidity cutoffs, refrigerant pressure monitoring, phase-loss detection, water-level interlock, and fault-event logging with timestamped event codes.
Sample Compatibility & Compliance
The chamber accommodates test specimens up to 1,200 mm × 1,000 mm × 900 mm (W×D×H), with a standard 50 mm diameter feedthrough port (left-side, sealed with silicone plug) for external power, sensor, or signal cabling. Internal rail-guided vibration table allows rapid insertion/removal without disassembly. All materials comply with RoHS Directive 2011/65/EU and REACH Annex XVII restrictions. Thermal and humidity control algorithms are validated per ISO/IEC 17025 calibration protocols; humidity sensors are NIST-traceable capacitive hygrometers with factory calibration certificates. The system supports compliance documentation packages aligned with automotive APQP Phase 3, aerospace AS9100 Rev D, and medical device ISO 13485:2016 requirements.
Software & Data Management
Equipped with proprietary WinTest Suite v4.2, the system enables remote monitoring, script-based test sequencing, and synchronized acquisition of temperature, humidity, and vibration acceleration (via optional analog input module). Data export formats include CSV, Excel (.xlsx), and binary TDMS (compatible with NI LabVIEW). Audit trail functionality complies with FDA 21 CFR Part 11 when paired with user authentication and electronic signature modules. Historical test logs are stored locally on industrial-grade SSD with 5-year retention capacity and support scheduled FTP/SFTP backup to network-attached storage.
Applications
- Aerospace avionics qualification per MIL-STD-810H Method 514.8 (vibration) and Method 502.7 (temperature/humidity).
- Automotive ECUs and battery management systems subjected to combined thermal shock and road-spectrum vibration per ISO 16750-4.
- 5G base station RF modules undergoing damp-heat endurance testing at 85 °C / 85% RH while vibrating at resonant frequencies.
- Medical imaging subsystems (e.g., MRI coil housings) validated for structural resonance avoidance under thermal gradient conditions.
- Consumer electronics PCB assemblies tested for solder joint fatigue using swept-sine vibration superimposed on −40 °C → +85 °C thermal ramps.
FAQ
Can the chamber operate continuously for extended durations (e.g., 720 hours)?
Yes—validated for unattended 3-month continuous operation under nominal load, with redundant compressor oil management and self-diagnostic cooling loop monitoring.
Is vibration isolation provided between the shaker and chamber structure?
Yes—the base frame incorporates active pneumatic isolators tuned to suppress transmission of non-test-frequency energy into the chamber support structure.
What humidity range options are available beyond standard 20–98% RH?
Optional low-humidity configuration extends down to 5% RH using desiccant-assisted drying; high-accuracy 10–98% RH mode employs dual-sensor differential compensation.
Does the system support third-party vibration controller integration (e.g., Vibration Research VR9500)?
Yes—RS485 and Ethernet/IP interfaces enable bidirectional synchronization of vibration profile triggers with thermal/humidity setpoint changes.
Are calibration certificates included with shipment?
NIST-traceable calibration reports for temperature, humidity, and vibration transducers are supplied; ISO/IEC 17025-accredited field calibration services are available upon request.
