LabCompanion HP-225U Programmable Temperature and Humidity Chamber

Overview

The LabCompanion HP-225U Programmable Temperature and Humidity Chamber is an engineered environmental test system designed for rigorous reliability assessment of electronic components, optoelectronic devices, printed circuit boards (PCBs), lithium-ion batteries, LCD modules, optical crystals, and fiber-optic assemblies under controlled thermal and hygrothermal stress conditions. It operates on the principle of precision-coupled thermodynamic regulation—utilizing dual-mode mechanical compression refrigeration (single-stage or cascade configuration), resistive heating, and steam-based humidification—to maintain stable, repeatable, and traceable environmental profiles across wide operational ranges. The chamber meets essential requirements for accelerated aging, qualification testing, and process validation in R&D laboratories, quality assurance departments, and manufacturing sites adhering to GLP, ISO/IEC 17025, and IATF 16949-aligned workflows.

Key Features

• High-efficiency dual-mode refrigeration architecture with imported hermetic rotary compressors (EU/US-sourced), enabling stable operation across extreme temperature transitions and extended duty cycles;
• SUS304 stainless steel interior and powder-coated exterior construction ensures long-term corrosion resistance, mechanical rigidity, and compliance with cleanroom-compatible surface standards;
• ETAC820 touchscreen controller featuring industrial-grade PLC core, 10.4-inch color HMI, 50 programmable test profiles (up to 2500 total steps), and real-time PID tuning with ±0.1 °C / ±1 %RH resolution;
• BTHC (Balanced Temperature & Humidity Control) algorithm ensures independent yet synchronized regulation of heating, cooling, humidification, and dehumidification subsystems—minimizing overshoot and improving spatial uniformity;
• Integrated LAN-based SCADA interface supporting up to 200 concurrent chamber units; enables centralized monitoring, remote alarm notification, and audit-ready event logging without physical cabling;
• USB data export functionality with non-volatile memory storage for time-stamped temperature/humidity trajectories, fault logs, and operator actions—fully compatible with FDA 21 CFR Part 11-compliant data integrity frameworks;
• Comprehensive safety architecture including dry-heater protection, independent overtemperature cutoff, refrigerant high-pressure interlock, earth-leakage detection, and automatic power recovery after interruption;
• Optimized airflow design with centrifugal circulation blower and directional ducting achieves ≤±2.0 °C and ≤±2.5 %RH uniformity across full working volume per IEC 60068-3-5 verification protocols.

Sample Compatibility & Compliance

The HP-225U accommodates a broad spectrum of sample types—from miniature semiconductor packages and flexible PCBs to full-size consumer electronics enclosures—via its 225 L internal cavity (500 × 750 × 600 mm W×H×D) and standard Φ50 mm cable port. Its performance envelope satisfies mandatory test conditions specified in GB/T 2423.1 (cold), GB/T 2423.3 (steady-state damp heat), GB/T 2423.4 (cyclic damp heat), MIL-STD-810D Method 502.2 (low temperature), Method 507.2 (humidity), and GJB 150.9 (military-grade wet heat). Optional dehumidification module extends operational RH range down to ≤10 %RH, supporting desiccation-sensitive validation protocols for moisture barrier packaging and MEMS device qualification. All control firmware and calibration records are structured to support ISO/IEC 17025 method validation and internal audit readiness.

Software & Data Management

The embedded ETAC820 controller provides native support for both fixed-value and multi-segment program execution, with user-defined ramp/soak profiles, conditional branching (e.g., “if T > 85 °C then activate dehumidifier”), and pattern-based cycling (1–999 iterations per group). Real-time graphical display overlays temperature and humidity curves, while built-in nonvolatile memory retains all runtime data—including timestamps, setpoint deviations, alarm triggers, and actuator status—even during power loss. Exported .CSV files are structured for direct import into statistical process control (SPC) platforms such as Minitab or JMP. Optional remote monitoring software enables role-based access control, automated report generation (PDF/Excel), and integration with enterprise LIMS or MES systems via RESTful API endpoints. All data handling complies with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available).

Applications

• Accelerated life testing of Li-ion battery cells under thermal-hygric stress to evaluate electrolyte decomposition and SEI layer stability;
• Qualification of automotive ECUs per ISO 16750-4 for climatic robustness in varying humidity regimes;
• Reliability screening of OLED displays and touch sensors exposed to condensation-prone environments;
• Material compatibility testing of conformal coatings, adhesives, and encapsulants per IPC-CC-830B;
• Process validation of reflow soldering fixtures subjected to pre-conditioning at elevated humidity prior to thermal shock;
• Environmental stress screening (ESS) of aerospace-grade connectors and RF modules per MIL-STD-883 Method 1004.2.
