LabCompanion P-Series High-Low Temperature & Humidity Environmental Test Chamber

Overview

The LabCompanion P-Series High-Low Temperature & Humidity Environmental Test Chamber is an engineered platform for controlled simulation of combined thermal and hygrometric stress conditions. Designed in accordance with international environmental testing standards—including IEC 60068-2-30 (damp heat, cyclic) and IEC 60068-2-78 (damp heat, steady state)—this chamber enables precise replication of real-world storage, transport, and operational environments. Its dual-parameter control architecture integrates high-fidelity temperature regulation via cascade or single-stage refrigeration with stable humidity generation using electric steam injection and saturated gas humidification. The chamber’s thermodynamic performance is anchored by a rigid polyurethane/glass fiber composite insulation layer, minimizing thermal bridging and ensuring energy-efficient operation across extended test cycles. All internal surfaces are fabricated from electropolished SUS304 stainless steel to resist corrosion and facilitate cleaning—critical for repeatable test integrity under high-humidity exposure.

Key Features

• Modular refrigeration design supporting both single-stage (for milder low-temperature ranges) and cascade systems (for −70°C capability), each equipped with a hermetically sealed Tecumseh compressor for long-term reliability and low maintenance.
• Programmable PID controllers from Shimaden (Japan), Honeywell (USA), or TEMI (Korea), offering multi-segment ramp-soak profiles, real-time digital display of setpoints and actual values, and intuitive touchscreen navigation.
• Dual-mode humidification: electric steam generator for rapid RH response and saturated gas system for enhanced stability at elevated humidity levels (≥90% RH).
• Uniform airflow distribution achieved via extended-shaft centrifugal fan with stainless steel impeller, ensuring ≤2°C temperature uniformity and ±2–3% RH consistency across the working volume.
• Robust safety architecture including independent over-temperature cut-off, leakage current protection, compressor high-pressure shutdown, and fast-blow fusing—fully compliant with IEC 61000-4 electromagnetic compatibility requirements.
• Precision-machined cold-rolled steel exterior with electrostatic powder coating, CNC-formed structural panels, and double-glazed observation window (220 × 180 mm) with internal heating to prevent condensation.

Sample Compatibility & Compliance

The P-Series accommodates a broad range of sample geometries—from compact electronic components and PCB assemblies to larger instrument enclosures and automotive ECUs—across working volumes spanning 50 L to 1500 L. Internal dimensions are optimized for unobstructed airflow and sensor placement per ISO 16750-4 and MIL-STD-810H Section 507.2. All models meet GB/T 10586–2014 (Environmental Testing Equipment General Requirements), GB/T 2423.3–2016 (damp heat, cyclic), and GB/T 2423.4–2016 (damp heat, steady state). Optional calibration certificates traceable to NIM (National Institute of Metrology, China) are available upon request. For regulated industries, the controller supports audit trail logging and user access levels compatible with GLP/GMP documentation workflows.

Software & Data Management

Standard configuration includes embedded data logging with ≥30-day memory retention (1-second sampling interval). Optional Ethernet or RS485 interfaces enable integration into centralized lab monitoring systems (e.g., LabVantage, Siemens Desigo, or custom SCADA). LabCompanion’s optional PC-based software provides real-time graphing, alarm event tagging, export to CSV/PDF, and password-protected parameter locking—supporting FDA 21 CFR Part 11 compliance when configured with electronic signature and change history modules. Raw sensor data (PT100 resistance, humidity capacitance output) is recorded without interpolation, preserving measurement fidelity for post-test root-cause analysis.

Applications

• Accelerated aging studies of polymer encapsulants, conformal coatings, and adhesives under thermo-hygrometric cycling.
• Qualification testing of automotive ECUs per ISO 16750-4 and AEC-Q200 requirements.
• Validation of medical device packaging integrity (ISO 11607) during accelerated shelf-life protocols.
• Reliability screening of consumer electronics per JEDEC JESD22-A108 and IPC-9701.
• Material property evaluation—including dimensional stability, creep behavior, and dielectric strength—under combined thermal/humidity stress.
• Environmental stress screening (ESS) and HALT/HASS pre-screening in manufacturing QA/QC labs.

FAQ

What temperature and humidity ranges are supported across P-Series models?
Standard configurations cover −70°C to +150°C (with optional extension to +200°C on select variants) and 30–98% RH. Specific operating envelopes depend on model size and refrigeration architecture; full specifications are provided in the technical datasheet per IEC 60068-3-5.

Is the chamber suitable for continuous operation in high-humidity conditions?
Yes. The dual humidification system, stainless steel interior, and heated observation window collectively mitigate condensation risk and corrosion potential, enabling uninterrupted operation at 95% RH and above for durations exceeding 1,000 hours.

Can the controller be validated for GxP environments?
The TEMI and Honeywell controllers support IQ/OQ documentation packages, configurable audit trails, and role-based user permissions—enabling validation against FDA 21 CFR Part 11, EU Annex 11, and ISO/IEC 17025 requirements when deployed with appropriate SOPs and calibration protocols.

Are custom modifications available—for example, additional ports or specialized shelving?
Yes. LabCompanion offers OEM engineering services including custom port layouts (NPT, CF flange), reinforced shelves for heavy loads (≤50 kg per shelf), inert gas purge inlets (N₂/Ar), and integrated vibration isolation mounts—subject to mechanical feasibility review and lead-time adjustment.
