Overview
The Custom-Built Compact & Medium-Sized Temperature and Humidity Controlled Chamber is an engineered environmental test system designed for precise, repeatable simulation of thermal and hygrothermal stress conditions. Based on the principle of forced-air convection with dual independent PID-controlled refrigeration and humidification subsystems, it delivers stable, traceable climate profiles across defined temperature and relative humidity (RH) ranges. This chamber is purpose-built for accelerated reliability testing of electronic components, automotive ECUs, aerospace avionics enclosures, polymer coatings, and pharmaceutical packaging—where compliance with international environmental stress screening protocols is mandatory. Its modular architecture supports full customization of internal volume (from 80 L to 1000 L), thermal ramp rates, and humidity resolution to match product-specific qualification requirements under ISO/IEC 17025-accredited lab environments.
Key Features
- Microprocessor-based color touchscreen controller with intuitive bilingual (English/Chinese) interface and real-time graphical trend display
- Double-layer high-tensile silicone rubber door gasket ensuring leak-tight sealing at extreme temperature/humidity extremes
- Internally and externally constructed from electropolished SUS#304 stainless steel for corrosion resistance and cleanroom compatibility
- Triple-pane insulated observation window with integrated conductive ITO film for anti-fog viewing and EMI-shielded visual monitoring
- Standard 50 mm diameter cable port (left-side mounted) with removable silicone plug for external sensor or power feedthrough
- Full-enclosed low-noise dual-stage cascade refrigeration system using environmentally compliant R404A/R23 refrigerant blend
- Integrated safety logic with automatic power cutoff and on-screen fault diagnostics for overtemperature, overhumidity, compressor overload, or sensor failure
Sample Compatibility & Compliance
The chamber accommodates a wide range of sample geometries and thermal masses through fully customizable internal dimensions (W×H×D: 40×50×40 cm to 100×100×100 cm). Standard configurations include two adjustable SUS#304 shelves and four locking casters with leveling feet. It meets the mechanical and climatic test requirements of multiple internationally recognized standards, including: MIL-STD-810G Method 501.6 (High Temperature), Method 502.6 (Low Temperature), Method 507.5 (Humidity), IEC 60068-2-1 (Cold), IEC 60068-2-2 (Dry Heat), IEC 60068-2-78 (Steady-State Damp Heat), and IEC 60068-2-30 (Cyclic Damp Heat). All models are compatible with GLP/GMP documentation workflows and support audit-ready calibration records per ISO/IEC 17025.
Software & Data Management
The embedded controller logs temperature and RH data at user-selectable intervals (1–60 seconds) with timestamped CSV export via USB or Ethernet. Optional PC-based software enables remote monitoring, multi-chamber synchronization, automated test sequencing (e.g., step, ramp-soak, cyclic profiles), and generation of ASTM-compliant test reports. Data integrity is maintained through password-protected user roles, electronic signature capability, and optional 21 CFR Part 11 compliance modules—including audit trail logging, data encryption, and electronic record retention policies aligned with FDA and EU Annex 11 requirements.
Applications
This chamber serves critical validation functions across regulated and industrial sectors: thermal cycling of printed circuit boards (PCBs) per IPC-9701; moisture sensitivity level (MSL) preconditioning of surface-mount devices (JEDEC J-STD-020); stability testing of medical device housings under ISO 11607; accelerated aging of lithium-ion battery modules; verification of HVAC control algorithms; and environmental stress screening (ESS) of military-grade connectors per MIL-PRF-28876. Its uniformity (±0.5 °C / ±2.5 %RH) and stability (±2 °C / +2–3 %RH) enable reproducible pass/fail determinations in QA/QC laboratories and R&D settings.
FAQ
What temperature and humidity ranges are available?
Standard configurations support temperature ranges from –70 °C to +150 °C (with optional ultra-low –70 °C stage) and humidity from 20–98 %RH (10–98 %RH and 5–98 %RH available as factory options).
Can the chamber be integrated into an existing lab automation network?
Yes—Ethernet and RS-485 interfaces support Modbus TCP/RTU communication for integration with SCADA, MES, or LIMS platforms.
Is calibration certification included?
Each unit ships with a NIST-traceable as-delivered calibration certificate for temperature and humidity sensors; annual recalibration services are available under service contract.
What power supply specifications are required?
Three-phase AC 380 V ±5 %, 50 Hz ±0.5 Hz, 5-wire configuration (L1/L2/L3/N/PE); 2.5 m power cord supplied.
How is thermal uniformity validated?
Uniformity is verified per IEC 60068-3-5 using nine-point sensor mapping during steady-state operation at key setpoints (e.g., 25 °C/50 %RH, 85 °C/85 %RH, –40 °C/20 %RH).
