LabCompanion P-Series2 Environmental Test Chamber

Overview

The LabCompanion P-Series2 Environmental Test Chamber is an engineered platform for precise, repeatable simulation of temperature and humidity stress conditions across industrial, automotive, aerospace, and electronics reliability testing applications. Based on forced-air convection thermodynamics and saturated steam humidification principles, the chamber delivers controlled thermal and hygrothermal environments compliant with international test standards including IEC 60068-2, MIL-STD-810H, ASTM D4332, and ISO 16750-4. Its dual-path refrigeration architecture—offering both single-stage and cascade configurations—enables stable operation from -70°C to +150°C, while the integrated PT100-sensor feedback loop and high-resolution programmable controller ensure traceable, reproducible profiles under GLP/GMP-aligned operational protocols.

Key Features

• Modular refrigeration design: Selectable single-stage or cascade (dual-stage) cooling system for extended low-temperature capability down to -70°C, using a hermetically sealed Tecumseh scroll compressor for long-term reliability and oil-free operation.
• Precision climate control: Digital PID-based programmable controller (Shinko, Honeywell, or TEMI) with real-time graphical display, multi-segment ramp-soak programming, and automatic data logging via RS485/USB interface.
• Uniform airflow architecture: Single-loop circulation driven by an extended-shaft stainless steel centrifugal fan ensures ≤2°C temperature uniformity and ±0.5°C stability throughout the working chamber volume.
• Dual humidification methodology: Combines electric steam generator (for rapid RH response) with saturated chamber humidification (for high-stability, low-drift operation at 30–98% RH).
• Robust mechanical construction: 304 stainless steel interior chamber; powder-coated cold-rolled steel outer enclosure fabricated via CNC machining for dimensional accuracy and structural integrity.
• Comprehensive safety redundancy: Independent over-temperature cutoff, leakage current protection, compressor high-pressure shutdown, and fast-blow fuse integration meet IEC 61000-4 EMC and UL 61010-1 safety requirements.

Sample Compatibility & Compliance

The P-Series2 accommodates diverse sample geometries—from PCB assemblies and battery modules to automotive ECUs and medical device enclosures—within standardized internal volumes ranging from 50 L to 1500 L (HP-50 to HS-1500 models). All variants comply with GB/T 10586–2014 (Chinese national standard for environmental test chambers), GB/T 2423.1–2022 (cold testing), GB/T 2423.2–2022 (dry heat), and GB/T 2423.3–2016 (damp heat). Optional calibration certificates are available per ISO/IEC 17025-accredited procedures, supporting audit readiness for FDA 21 CFR Part 11, ISO 9001:2015, and IATF 16949 quality management systems.

Software & Data Management

The embedded controller supports up to 99 programmable test cycles with 999 segments per cycle, including conditional branching (e.g., “hold until RH reaches 85%”). Data export is supported in CSV format via USB or serial connection. For enterprise integration, optional LabCompanion TestSuite™ software provides remote monitoring, alarm notification (email/SMS), electronic signature support, and 21 CFR Part 11-compliant audit trails—including user action logs, parameter change history, and timestamped environmental records. All firmware updates maintain backward compatibility and are validated per IEC 62304 Class B software lifecycle requirements.

Applications

• Accelerated life testing of lithium-ion battery cells under thermal cycling (-40°C ↔ +85°C) and humidity soak (85% RH, 85°C).
• Qualification of automotive infotainment units per ISO 16750-4 for thermal shock and damp heat resistance.
• Stability assessment of pharmaceutical packaging materials under ICH Q1A(R2) long-term and accelerated storage conditions.
• Environmental stress screening (ESS) of avionics components prior to HALT/HASS deployment.
• Validation of sensor drift characteristics in optical encoders and MEMS accelerometers across defined thermal-hygrometric boundaries.

FAQ

What temperature and humidity ranges are achievable with the P-Series2?
Standard operation spans -70°C to +150°C and 30–98% RH. Specific configuration (e.g., cascade refrigeration, enhanced insulation) determines exact low-temperature limit and humidity recovery time.
Is the chamber compatible with automated test sequencing and data archiving?
Yes—via RS485 Modbus RTU or optional Ethernet interface, it integrates with SCADA platforms and supports scheduled data export, alarm logging, and electronic signature workflows aligned with 21 CFR Part 11.
How is temperature uniformity verified and maintained across the working volume?
Uniformity is ensured through calibrated airflow modeling, validated during factory acceptance testing (FAT) per IEC 60068-3-5. Internal air velocity profiling and sensor placement follow ASTM E2297 guidelines.
Can the unit be configured for rapid thermal cycling (e.g., 10°C/min ramp rates)?
Yes—select models support configurable heating/cooling rates up to 10°C/min, achieved via optimized refrigerant charge, oversized condenser surface area, and high-capacity resistive heaters.
What documentation is provided for regulatory compliance and validation?
Standard delivery includes IQ/OQ protocol templates, calibration certificates (traceable to NIM), and a full technical file per EU Machinery Directive 2006/42/EC and CE marking requirements.
