LabCompanion PDR-800 Temperature and Humidity Environmental Test Chamber

Overview

The LabCompanion PDR-800 is a precision-engineered upright environmental test chamber designed for rigorous temperature and humidity conditioning of materials, components, and finished products under controlled, repeatable conditions. It operates on the principle of forced-air convection combined with dual independent PID-controlled refrigeration and humidification systems, enabling stable simultaneous regulation across wide thermal and hygroscopic ranges. The chamber supports both steady-state and dynamic cycling protocols—including high-low temperature alternating tests with humidity overlay—making it suitable for accelerated aging, reliability screening, and qualification testing in accordance with international standards such as IEC 60068-2-1, IEC 60068-2-2, IEC 60068-2-14, and ISO 16750-4. Its robust stainless-steel inner chamber, double-wall insulation, and leak-tight sealing ensure long-term stability and minimal energy drift during extended operational cycles.

Key Features

• Wide operational range: −20 ℃ to +150 ℃ temperature control with 5–98 % RH humidity capability, supporting both dry heat and high-humidity stress profiles.
• High-precision climate control: Temperature fluctuation maintained within ±0.5 ℃; humidity deviation limited to ±2.5 % RH under standard operating conditions.
• Optimized thermal dynamics: Non-linear heating rate of approximately 3.5 ℃/min (20 ℃ → +150 ℃, unloaded), achieved via high-capacity resistive heaters and intelligent ramp profiling.
• Industrial-grade construction: 304 stainless-steel interior chamber, double-layer insulated walls with polyurethane foam (≥100 mm thickness), and reinforced door gasketing for thermal integrity.
• Dual independent control loops: Separate PID algorithms govern refrigeration (cascade R404A/R23 system) and steam-based humidification (ultrasonic pre-humidifier + electric steam generator), minimizing cross-interference.
• Integrated safety architecture: Over-temperature cutoff, compressor high-pressure protection, humidity sensor fault detection, and emergency power-off circuitry compliant with IEC 61000-6-2 EMC requirements.

Sample Compatibility & Compliance

The PDR-800 accommodates large-format samples up to 1000 × 1000 × 800 mm (internal volume: 0.8 m³), ideal for automotive ECUs, PCB assemblies, medical device packaging, polymer sheets, and battery modules. Its uniformity profile (±1.5 ℃ / ±3.0 % RH across working volume per IEC 60068-3-5) ensures representative exposure for multi-point validation. The chamber meets essential regulatory prerequisites for GLP-compliant laboratories and supports audit-ready documentation when paired with optional data logging hardware. While not certified for Class I Div 1 hazardous locations, its design aligns with general-purpose industrial safety practices per UL 61010-1 and CE Machinery Directive 2006/42/EC.

Software & Data Management

The embedded controller features a 7-inch color touchscreen HMI with intuitive menu navigation, real-time graphing, and programmable multi-step profiles (up to 99 segments, 999 cycles). Optional Ethernet or RS485 interfaces enable integration with centralized SCADA or LIMS platforms. When configured with LabCompanion’s optional DataLogger Pro software (v3.2+), the system provides FDA 21 CFR Part 11–compliant electronic records—including user authentication, audit trails, digital signatures, and encrypted raw data export in CSV or XML formats. All temperature and humidity readings are timestamped with millisecond resolution and traceable to NIST-traceable reference sensors calibrated annually per ISO/IEC 17025 guidelines.

Applications

• Electronics reliability testing: Thermal cycling of PCBs, solder joint fatigue analysis, and moisture sensitivity level (MSL) evaluation per J-STD-020.
• Automotive component validation: Climate endurance of infotainment units, ADAS sensors, and EV battery enclosures per ISO 16750-4 and SAE J2380.
• Pharmaceutical packaging stability: Accelerated degradation studies of blister packs and HDPE containers under ICH Q1A(R2) recommended conditions.
• Polymer and composite aging: Hydrothermal degradation assessment of adhesives, sealants, and fiber-reinforced composites per ASTM D570 and ISO 62.
• Quality assurance in manufacturing: Final product burn-in, incoming material quarantine, and batch release verification in ISO 9001-certified facilities.

FAQ

What is the maximum allowable sample load for thermal uniformity compliance?
For guaranteed uniformity within ±1.5 ℃ and ±3.0 % RH, total sample volume should not exceed 30 % of internal chamber volume (i.e., ≤0.24 m³). Load configuration must allow unobstructed airflow around all surfaces.
Does the PDR-800 support programmable ramp-soak-cycle profiles with humidity modulation?
Yes. It supports fully customizable multi-segment profiles where temperature and humidity setpoints, rates, dwell times, and transition modes (linear or step) are independently defined per segment.
Is third-party calibration certification included with delivery?
Factory calibration certificates (traceable to national standards) are provided. Full ISO/IEC 17025-accredited calibration with uncertainty budgets is available as an optional service.
Can the chamber operate continuously at −20 ℃ and 95 % RH simultaneously?
No. At sub-zero temperatures, condensation risk limits practical humidity operation to ≤85 % RH below 0 ℃. The system enforces interlock logic to prevent incompatible setpoint combinations.
What maintenance intervals are recommended for optimal performance?
Refrigerant oil and filter-drier replacement every 24 months; steam generator descaling every 3 months (frequency increases with local water hardness); annual verification of sensor accuracy and door seal integrity.
