Overview
The LabCompanion PS-225 is a high-performance environmental test chamber engineered for precise and stable simulation of extreme temperature and humidity conditions across industrial R&D, quality assurance, and reliability validation workflows. Built upon a dual-refrigerant compressor cooling architecture and integrated PID-controlled humidification system, the PS-225 delivers reproducible thermal-hygrometric profiles in accordance with IEC 60068-2, MIL-STD-810H, and GB/T 2423 series standards. Its operational envelope spans from -70 °C to +150 °C with programmable relative humidity control (10–98% RH, optional), enabling comprehensive stress testing of electronic assemblies, polymer components, battery modules, aerospace avionics, and medical device packaging under defined climatic loads. The chamber’s low-noise mechanical design—achieved via vibration-damped compressor mounting, acoustic insulation layers, and optimized airflow distribution—ensures compatibility with noise-sensitive laboratory environments, including metrology labs and academic cleanroom facilities.
Key Features
- Robust stainless-steel inner chamber construction with seamless welding and anti-corrosion surface treatment for long-term stability in humid cycling tests.
- High-efficiency cascade refrigeration system with environmentally compliant R404A/R23 refrigerant blend, enabling rapid cooling to -70 °C without liquid nitrogen dependency.
- Intelligent microprocessor controller with 10-inch color touchscreen interface, supporting up to 100 programmable test profiles, each with 99 segments and loop capability.
- Real-time monitoring of chamber temperature, humidity, dew point, and system status via embedded Ethernet port and optional RS485/Modbus RTU connectivity.
- Low-noise operation (<62 dB(A) at 1 m distance) achieved through precision-balanced fan impellers, acoustic-absorbing chamber lining, and active vibration isolation mounts.
- Comprehensive safety architecture including over-temperature protection, refrigerant pressure monitoring, door interlock, and emergency power-off circuitry compliant with IEC 61000-6-2 EMC requirements.
Sample Compatibility & Compliance
The PS-225 accommodates a broad range of sample types—from PCB subassemblies and lithium-ion pouch cells to automotive ECUs and pharmaceutical blister packs—within its customizable internal workspace. All chamber configurations undergo factory calibration traceable to NIM (National Institute of Metrology, China) standards, with optional ISO/IEC 17025-accredited calibration certificates available upon request. The system meets essential regulatory expectations for environmental qualification testing under ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 quality management frameworks. For GxP-regulated applications, optional audit-trail-enabled software modules support 21 CFR Part 11 compliance, including electronic signatures, user access controls, and immutable data logging.
Software & Data Management
LabCompanion’s proprietary ChamberControl™ software enables remote monitoring, real-time graphing, automated report generation (PDF/CSV), and alarm event logging via Windows-based desktop or web browser interfaces. Data integrity safeguards include cyclic redundancy check (CRC)-verified file storage, timestamped version history, and encrypted local database backups. Integration with enterprise LIMS or MES platforms is supported through OPC UA and RESTful API protocols. Optional cloud synchronization allows secure off-site data archiving and multi-site fleet management for centralized QA departments.
Applications
- Accelerated life testing of consumer electronics per JEDEC JESD22-A104 and A119 standards.
- Thermal cycling validation of EV battery packs under combined temperature/humidity stress (e.g., UN 38.3 Section 38.3.4).
- Material aging studies on elastomers, adhesives, and composite laminates per ASTM D3045 and ISO 11341.
- Environmental stress screening (ESS) of military-grade connectors and radar subsystems in accordance with MIL-STD-2164.
- Stability testing of sterile medical devices per ISO 11607-1 and ICH Q1A(R2) guidelines.
- Pre-compliance verification for CE marking under EN 60068-2-1, -2, -14, and -30.
FAQ
What is the standard warranty period for the PS-225 chamber?
LabCompanion provides a 24-month limited warranty covering parts and labor for defects in materials and workmanship, excluding consumables and user-induced damage.
Can the PS-225 be configured for humidity control?
Yes—while the base PS-225 model operates as a dry-temperature-only chamber, the PS-225H variant adds full-range humidity control (10–98% RH) with steam generator and dehumidification coil.
Is third-party calibration documentation included with shipment?
A factory calibration report (traceable to national standards) is provided. ISO/IEC 17025-accredited calibration is available as an add-on service prior to delivery.
Does the chamber support custom test protocols beyond standard ramp-soak cycles?
Yes—the controller supports complex multi-step profiles with conditional branching, real-time parameter overrides, and external trigger inputs via digital I/O ports.
How is maintenance access designed for field service?
Front-accessible refrigeration components, modular electrical panels, and tool-free filter replacement minimize downtime; service manuals and diagnostic flowcharts are provided in English and Chinese.
