LabCompanion HP-150A Temperature and Humidity Controlled Environmental Test Chamber

Overview

The LabCompanion HP-150A Temperature and Humidity Controlled Environmental Test Chamber is an engineered solution for evaluating the physical integrity, functional reliability, and long-term stability of materials, components, and finished products under precisely regulated thermal and hygrothermal stress conditions. Designed in accordance with international environmental testing standards—including IEC 60068-2-1 (cold), IEC 60068-2-2 (dry heat), IEC 60068-2-78 (damp heat, cyclic), and aligned with GB/T 2423.22–2012 and GB/T 10589–2008—this chamber supports both static (constant) and dynamic (programmed) test profiles. Its core architecture integrates a high-efficiency dual-stage refrigeration system, precision PT100 resistance temperature detectors, and capacitive humidity sensors calibrated traceably to NIST-traceable references. The chamber operates on a robust PID control algorithm, ensuring stable setpoint maintenance and minimal overshoot during rapid transitions across wide temperature spans.

Key Features

• Stainless steel interior (SUS304 mirror-finish) and insulated outer casing (powder-coated or brushed stainless steel) for corrosion resistance and thermal integrity
• High-density rigid polyurethane foam insulation (glass wool alternative at ≥150°C operation) minimizing thermal leakage and energy consumption
• Full-enclosed industrial-grade compressor system with cascade configuration for reliable low-temperature performance down to –40°C
• Standard features include two adjustable stainless steel shelves, Ø50 mm cable/port access port, double-layer heated observation window, and internal LED lighting
• LCD-based controller with full English menu navigation, real-time curve display, and programmable multi-step cycles (up to 99 segments)
• Integrated safety functions: over-temperature alarm, power failure recovery, self-diagnostic error logging, and automatic start/stop timing

Sample Compatibility & Compliance

The HP-150A accommodates diverse sample geometries within its 150 L internal volume (500 × 600 × 500 mm), supporting standard test specimens per ASTM D4329 (plastics), ISO 9022-2 (optical instruments), MIL-STD-810H Method 502.7 (low temperature), and Method 507.6 (humidity). Its humidity control system maintains stable vapor pressure conditions between 20% and 98% RH at temperatures from 10°C to 85°C, meeting requirements for accelerated aging, condensation resistance, and moisture absorption testing. All operational parameters—including temperature ramp rates, dwell times, and humidity stabilization—are fully traceable and auditable, supporting GLP-compliant documentation workflows. Optional LAN interface enables remote monitoring and integration into centralized laboratory data management systems compliant with FDA 21 CFR Part 11 requirements.

Software & Data Management

The embedded controller provides local data logging with timestamped records for temperature, humidity, and alarm events (retained for ≥30 days). Optional Ethernet connectivity allows seamless export of CSV-formatted logs via TCP/IP to external SCADA or LIMS platforms. Real-time trend visualization includes overlay plots for dual-channel sensor validation and deviation alerts against user-defined tolerances. Configuration files (test programs, calibration offsets, user permissions) are password-protected and exportable for backup or cross-chamber replication. Audit trail functionality logs all operator actions—including parameter changes, manual overrides, and calibration entries—with immutable timestamps—meeting ISO/IEC 17025 clause 7.7 and GxP data integrity expectations.

Applications

• Qualification testing of PCBs, semiconductors, and automotive ECUs under thermal cycling and damp heat exposure
• Stability assessment of pharmaceutical packaging materials per ICH Q1A(R2) guidelines
• Evaluation of polymer dimensional stability, seal integrity, and coating adhesion under combined thermal-hygrometric stress
• Pre-conditioning of sensors, optical lenses, and precision mechanical assemblies prior to metrological calibration
• Environmental screening of aerospace fasteners, composites, and thermal interface materials per RTCA DO-160 Section 4 and 5
• Validation of battery cell behavior (Li-ion, solid-state) during charge/discharge cycles under controlled ambient conditions

FAQ

What is the maximum allowable sample mass for thermal stability without compromising chamber performance?
Chamber thermal load capacity is validated up to 15 kg of non-heat-generating inert mass; active thermal mass (e.g., powered devices) requires derating per manufacturer’s thermal load calculation sheet.
Does the HP-150A support automated compliance reporting per ISO/IEC 17025?
Yes—when configured with optional LAN module and LabCompanion’s certified DataBridge software, it generates PDF reports with electronic signatures, calibration traceability, and uncertainty budgets aligned with ISO/IEC 17025 Annex A.3.
Can the controller be calibrated independently of service visits?
Field calibration is supported using certified reference sensors (NIST-traceable PT100 and humidity probes); offset adjustments are password-locked and logged in the audit trail.
Is the chamber suitable for continuous operation at 150°C and 98% RH?
Continuous operation at 150°C is permitted; however, sustained 98% RH above 85°C is not recommended due to condensation risk and sensor drift—maximum recommended humidified temperature is 85°C.
What documentation is provided for regulatory audits?
Factory calibration certificate, IQ/OQ protocol templates, traceable sensor calibration reports, and full electrical safety certification (CB Scheme, CE, RoHS) are included with shipment.
