Overview
The Custom-Built Large-Scale Temperature & Humidity Environmental Chamber is an engineered solution for laboratories and industrial R&D facilities requiring precise, repeatable, and programmable environmental simulation across extreme thermal and hygrothermal conditions. Designed around a robust dual-loop control architecture—separately regulating refrigeration, heating, and humidification subsystems—the chamber implements a balanced temperature-humidity conditioning method that minimizes overshoot and stabilizes setpoints within tight tolerances. Its operational envelope spans −40 °C to +150 °C with humidity control from 20% to 98% RH (dependent on temperature), making it suitable for accelerated aging, reliability validation, and qualification testing of electronics, aerospace components, automotive modules, and packaging materials under IEC, MIL-STD, and GB-compliant test profiles.
Key Features
- Microprocessor-based intelligent controller with dual-directional PID logic, enabling high-fidelity tracking of complex multi-step temperature/humidity profiles
- Integrated RS-232C and RS-485 communication interfaces supporting remote monitoring, centralized system integration, and SCADA compatibility
- Dual independent safety interlocks: hardware-level over-temperature cutoff and software-configurable alarm thresholds with audible (buzzer) and visual (LED) alerts
- Self-diagnostic refrigeration circuit with auto-selection logic—enabling direct compressor activation during high-temperature soak phases without pre-cooling delay
- Optimized thermal insulation using ≥100 mm thick, low-conductivity glass wool with seamless joint sealing to minimize thermal bridging and energy loss
- Full-view observation window with integrated LED lighting and anti-fog coating for real-time visual inspection without compromising chamber integrity
- Programmable functions including power failure recovery, start delay scheduling, profile editing, and parameter lockout for GLP/GMP environments
Sample Compatibility & Compliance
This chamber accommodates samples up to 400 × 400 × 500 mm (W × H × D) and supports load-dependent thermal mass compensation through adaptive control algorithms. It conforms to multiple international and national environmental test standards, including IEC 60068-2-1 (Cold), IEC 60068-2-2 (Dry Heat), MIL-STD-810G Method 502.5 (Low Temperature) and Method 501.5 (High Temperature), as well as GB/T 5170.2–2017 (Temperature Testing Equipment Verification), GB/T 5170.5–2016 (Humidity Testing Equipment Verification), and GB/T 10586–2006 (Environmental Test Chambers General Requirements). All calibration points are traceable to NIST-equivalent national metrology institutes via third-party certified verification reports.
Software & Data Management
The embedded controller supports full-cycle data logging at user-defined intervals (1–600 seconds), storing up to 1,000 hours of time-stamped temperature and humidity readings internally. Optional Ethernet or USB export enables CSV-formatted data transfer for post-processing in MATLAB, Python (Pandas), or statistical analysis platforms. The system complies with FDA 21 CFR Part 11 requirements when paired with optional audit-trail-enabled firmware—providing electronic signatures, immutable log history, and role-based access control for regulated QA/QC labs. Optional external humidity recorders (e.g., Vaisala HMP155) may be integrated via analog 4–20 mA or Modbus RTU for redundant validation.

- Automotive component qualification per GMW3172, Ford CETP 00.00-L-467, and VW 80101
FAQ
What is the maximum sample weight this chamber can accommodate without compromising performance?
The chamber is rated for static loads up to 50 kg distributed evenly on the standard stainless steel shelf. For heavier or thermally massive samples, optional reinforced shelving and extended stabilization time protocols are recommended.
Does the system support humidity control below 0 °C?
Humidity control is not active below +5 °C due to condensation and frost risk on sensor elements; dehumidification is disabled in sub-zero operation per IEC 60068-3-5.
Can the controller be validated for 21 CFR Part 11 compliance?
Yes—when equipped with optional audit-trail firmware, electronic signature module, and password-protected configuration access, the system meets baseline Part 11 technical controls for closed systems.
Is third-party calibration certification included with delivery?
A factory-issued calibration certificate (covering temperature uniformity, accuracy, and stability at three points: −40 °C, 25 °C, and +150 °C) is provided. ISO/IEC 17025-accredited field calibration is available as a separate service.
What refrigerant is used in the cooling system?
R-404A or R-507A refrigerant is employed in the hermetic scroll compressor system, compliant with current EU F-Gas Regulation Annex I phase-down schedules and EPA SNAP-approved alternatives.
