OK-ES-200 Combined Temperature-Humidity-Vibration Environmental Test Chamber

Overview

The OK-ES-200 Combined Temperature-Humidity-Vibration Environmental Test Chamber is an integrated reliability validation platform engineered for accelerated life testing and transport simulation under synchronized climatic and mechanical stress conditions. It combines precision-controlled thermal-hygrometric environments with high-fidelity electrodynamic vibration excitation—operating on the principle of controlled sinusoidal displacement and acceleration synthesis—to replicate real-world distribution hazards including road transport vibration spectra, warehouse temperature/humidity cycling, and stacking-induced fatigue. Unlike sequential single-stress testing, this triaxial (temperature, humidity, vibration) chamber enables concurrent exposure, revealing synergistic failure mechanisms such as condensation-assisted solder joint cracking, hygroscopic swelling under dynamic strain, or polymer creep accelerated by thermal cycling. Designed for compliance-driven industries—including automotive electronics (ISO 16750-3), medical device packaging (ISO 11607-2), and consumer electronics (ISTA 3A, MIL-STD-810H Method 514.8)—the system supports deterministic test profiles required for design verification, qualification, and production lot screening.

Key Features

• Simultaneous triple-stress conditioning: independent PID-controlled temperature (−40°C to +150°C) and humidity (10–98% RH) chambers integrated with a high-dynamic-range electrodynamic shaker
• Multi-axis vibration capability: vertical + horizontal orthogonal excitation with programmable phase relationship; 20 g peak acceleration at full load (100 kg)
• High-resolution motion control: 0.01 Hz frequency resolution, ±0.1 Hz accuracy across 5–60 Hz operating band; amplitude continuously adjustable from 0 to 5 mm (p-p)
• Dual independent display interface: real-time side-by-side monitoring of commanded vs. measured frequency and rotational speed (RPM), eliminating manual unit conversion
• Advanced profile programming: 30-segment user-defined sequences supporting sweep, logarithmic, octave, and custom time–frequency trajectories—all with cycle repetition and breakpoint hold
• Structural isolation system: proprietary high-damping elastomeric mounting feet suppress floor-borne resonance transmission, enabling installation in shared industrial facilities without structural reinforcement
• Robust mechanical architecture: rigid steel-reinforced worktable (1100 × 800 mm), reinforced frame, and sealed vibration feedthroughs for long-term operational stability under continuous duty

Sample Compatibility & Compliance

The OK-ES-200 accommodates heterogeneous sample geometries—from PCB assemblies and handheld devices to packaged furniture and ceramic ware—via standardized mounting interfaces and customizable fixture plates. Its 100 kg payload capacity supports stacked palletized loads (e.g., ISTA 3E-compliant configurations) and large-format enclosures. The chamber meets core environmental test standards including IEC 60068-2-6 (vibration), IEC 60068-2-14 (thermal shock), and IEC 60068-2-78 (damp heat). Optional data logging modules support audit-ready traceability per ISO/IEC 17025 and FDA 21 CFR Part 11 requirements, with timestamped parameter records, operator ID tagging, and electronic signature workflows. Calibration certificates traceable to NIST or PTB standards are available upon request.

Software & Data Management

Control is executed via embedded real-time OS with Ethernet-enabled remote operation (TCP/IP). The included PC software provides graphical profile editor, live FFT spectral view, and post-test report generation in PDF/CSV formats. All test logs—including setpoints, actual chamber/shaker parameters, alarms, and system diagnostics—are stored with SHA-256 hash integrity verification. Audit trail functionality records every parameter change, user login/logout, and firmware update event—fully compliant with GLP and GMP documentation protocols. Optional integration with LIMS or MES systems is supported via OPC UA and Modbus TCP interfaces.

Applications

• Transport simulation: Replicating multi-hour truck/vessel vibration spectra while maintaining specified temperature-humidity profiles to evaluate package integrity and product survivability
• Early-life failure detection: Identifying latent defects in solder joints, adhesive bonds, and MEMS components through accelerated fatigue under combined thermal-mechanical stress
• Packaging validation: Quantifying cushioning performance, corrugated board compression loss, and seal integrity degradation under cyclic humidity and vibration
• Material aging studies: Assessing polymer embrittlement, coating delamination, and battery electrolyte evaporation kinetics under synergistic stress conditions
• Design verification: Supporting DFMEA-driven test plans for automotive ECUs, aerospace avionics housings, and industrial IoT sensors exposed to harsh field environments

FAQ

What standards does the OK-ES-200 support for combined environment testing?
It natively supports test methods defined in ISTA 3A/3E, ISO 16750-3, MIL-STD-810H Method 514.8, and IEC 60068-2 series. Custom profiles can be configured to match internal corporate specifications.
Can the vibration and climate systems operate independently?
Yes—each subsystem (temperature/humidity chamber, vertical shaker, horizontal shaker) can be operated in standalone mode or fully synchronized with precise temporal alignment.
Is third-party calibration and certification available?
Certified calibration services—including uncertainty budgets and traceable certificates per ISO/IEC 17025—are offered by authorized metrology partners globally.
What safety interlocks are implemented?
The system includes door position sensing, over-temperature/over-humidity cutoffs, shaker over-acceleration shutdown, emergency stop circuitry compliant with IEC 60204-1, and automatic fault logging.
How is data integrity ensured during extended tests (e.g., 72+ hours)?
Non-volatile memory buffers all sensor data at 100 Hz sampling rate; redundant local storage and optional cloud backup prevent data loss due to power interruption or network failure.
