LabCompanion RP-80 Temperature and Humidity Environmental Test Chamber

Overview

The LabCompanion RP-80 Temperature and Humidity Environmental Test Chamber is an engineered platform for precise, repeatable simulation of climatic stress conditions across a wide operational envelope. Designed according to fundamental thermodynamic and psychrometric principles, the chamber employs dual independent control loops—separate PID-regulated heating, refrigeration, humidification, and dehumidification subsystems—to achieve high-fidelity replication of real-world environmental profiles. Its core architecture supports accelerated life testing, reliability validation, and qualification protocols mandated by international product development workflows. The system operates within a temperature range of –20°C to +150°C (with optional extensions to –80°C), and a humidity range of 30–98% RH, enabling compliance-driven evaluation of materials, electronics, automotive components, and packaging under combined thermal and hygroscopic stress.

Key Features

• Independent thermal and humidity control systems ensure minimal cross-interference and enhanced stability during dynamic profile execution.
• High-precision PT100 platinum resistance sensors (±0.1°C temperature, ±1% RH humidity indication accuracy) provide traceable metrological integrity for calibration-sensitive applications.
• Cascade or single-stage air-cooled refrigeration circuitry using original French TECO hermetic compressors delivers consistent low-temperature performance with optimized energy efficiency.
• Stainless steel surface-evaporation humidifier with automatic water recovery reduces consumables usage and supports unattended long-duration tests.
• Dual-layer high-tensile silicone door gasket and SUS304 mirror-finish inner chamber minimize leakage and corrosion, ensuring long-term repeatability and ease of cleaning.
• 5.7-inch Korean touchscreen controller with EN/CN language toggle, real-time curve plotting, and programmable logic supporting up to 100 test programs, each with 1000 segments and 999 cycles.
• RS-232/RS-485 serial interface enables remote monitoring, automated data logging, and integration into centralized laboratory management systems (LIMS).

Sample Compatibility & Compliance

The RP-80 accommodates a broad spectrum of sample geometries and material classes—including PCB assemblies, polymer films, battery cells, medical device housings, and aerospace composites—within its standard internal volume (450 × 450 × 500 mm). Optional larger configurations (GD(J)S series) extend working dimensions up to 1000 × 1000 × 1000 mm. All variants conform to key national standards governing environmental testing: GB/T 2423.1 (cold), GB/T 2423.2 (dry heat), GB/T 2423.3 (damp heat, steady state), and GB/T 2423.4 (damp heat, cyclic). While not pre-certified to ISO 17025 or IEC 60068-2 series out-of-the-box, the chamber’s documented control accuracy, sensor traceability, and programmable audit trail functionality support user-led validation for GLP/GMP-aligned quality systems.

Software & Data Management

The embedded microprocessor controller provides full-cycle test orchestration without external PC dependency. It features built-in power-loss recovery, screen lockout to prevent unauthorized parameter changes, and automatic correction algorithms that dynamically adjust setpoints in response to ambient load variations. For extended data governance, the RS-232/RS-485 port permits bidirectional communication with third-party SCADA or LIMS platforms. Users may export time-stamped temperature/humidity logs in CSV format, configure email alerts for alarm events (e.g., over-temperature, low water), and generate PDF-formatted test reports compliant with internal QA documentation requirements. Firmware updates are delivered via USB, maintaining version control and cybersecurity hygiene.

Applications

• Electronics reliability assessment: thermal cycling, damp heat aging, and solder joint fatigue simulation per IPC-TM-650 and JEDEC JESD22-A104.
• Automotive component validation: interior trim warpage, seal compression set, and ECU housing dimensional stability under combined thermal-hygric loading.
• Pharmaceutical packaging integrity testing: blister foil delamination, vial stopper migration, and desiccant efficacy under accelerated humidity exposure.
• Polymer and composite material characterization: glass transition shifts, moisture diffusion coefficients, and creep behavior under sustained thermo-hygrometric stress.
• Quality assurance in manufacturing: incoming inspection of raw materials, in-process verification of curing parameters, and final product release testing.

FAQ

What is the standard internal volume of the RP-80 model?

The RP-80 has a working chamber dimension of 450 × 450 × 500 mm (D × W × H), yielding a net volume of approximately 101 liters.
Can the chamber be configured for –80°C operation?

Yes—while the base RP-80 supports –20°C to +150°C, optional low-temperature packages extend the range to –40°C, –60°C, or –80°C using a cascade refrigeration system.
Is the controller compliant with FDA 21 CFR Part 11 requirements?

The controller supports audit trail generation and user-access controls but requires configuration and validation by the end user to meet Part 11 criteria for electronic records and signatures.
How is humidity calibrated and maintained over time?

Humidity sensing relies on industrial-grade capacitive RH transducers, calibrated against NIST-traceable reference standards. Automatic self-diagnostics flag drift exceeding ±2% RH, prompting recalibration.
What safety protections are integrated into the system?

Comprehensive safeguards include over-temperature cutoff, compressor high-pressure shutdown, motor overcurrent protection, water-level interlock, phase failure detection, and emergency power-off circuitry meeting IEC 61000-4 immunity standards.
