Overview
The PULUODY OMS-IIA01 Integrated Oil Particle Contamination Monitoring System is an industrial-grade optical particle counter engineered for high-reliability, real-time assessment of solid particulate contamination in liquid media—primarily hydraulic oils, turbine oils, aviation lubricants, phosphate ester hydraulic fluids, and other demanding service fluids. It operates on the light obscuration (LO) principle: particles suspended in a laminar-flow stream pass through a focused dual-laser beam; each particle generates a transient pulse proportional to its cross-sectional area. The seventh-generation dual-laser narrow-beam sensor enhances signal stability, reduces noise-induced false counts, and improves sizing resolution across ultra-fine (0.03 µm) to coarse (3000 µm) ranges. Designed for both online process integration and offline laboratory analysis, the OMS-IIA01 delivers continuous, unattended monitoring capability with embedded compliance logic for ISO 4406, NAS 1638, GJB 420B, and pharmacopeial standards (USP , EP 8.0, ChP 2015). Its architecture supports long-term deployment in harsh environments—including high-pressure hydraulic circuits, aerospace ground support systems, naval propulsion plants, and power generation turbine lube oil loops—without degradation in counting fidelity or calibration traceability.

Sample Compatibility & Compliance
The OMS-IIA01 accommodates a broad spectrum of liquid matrices without pre-filtration or dilution: mineral- and synthetic-based lubricants, aviation fuels (Jet A-1, JP-5), phosphate ester hydraulic fluids (e.g., Skydrol®), transformer insulating oils, gear oils, greases (in carrier solvent), ultrapure water, aqueous cleaning solutions, and pharmaceutical-grade solvents. It meets stringent regulatory and industry-specific requirements including ISO 4406:2021 (hydraulic fluid cleanliness), NAS 1638 Class 00–12, SAE AS4059F (aerospace fluid cleanliness), GJB 420B (Chinese military specification), DL/T 432 (power plant turbine oil), and pharmacopeial methods for particulate matter in injectables (USP , EP 8.0, ChP 2015). For filter performance evaluation, it complies with ISO 16889, GB/T 30176, and GB/T 18853. All measurement data are generated under conditions compliant with GLP principles; audit trails, user access logs, and electronic signatures may be enabled per FDA 21 CFR Part 11 when integrated with validated software platforms.
Software & Data Management
The system runs P6.4 Analysis Software (integrated firmware + PC version), offering modular workflows for calibration, validation, testing, and reporting. Calibration modules support MTD/ISO 11171, ACFTD/ISO 4402, and PSL sphere reference standards (ASTM F658-87). Validation protocols include linearity, limit of detection (LOD), precision (RSD <3%), and carryover assessment. Data output includes raw pulse histograms, cumulative/differential distribution curves, ISO 4406 code assignment, NAS class, and custom grading tables. Results are exportable as CSV, PDF, or XML; stored locally (up to 6,000 test records) or transmitted via RS232/USB to LIMS or CMMS. Software supports multi-user role-based access control, electronic signature capture, and full audit trail logging—including parameter changes, calibration events, and report generation—to satisfy GMP/GLP documentation requirements.
Applications
The OMS-IIA01 serves critical functions across sectors where fluid integrity directly impacts safety, reliability, and lifecycle cost. In aerospace, it monitors hydraulic fluid cleanliness in flight control systems and ground test rigs; in power generation, it tracks turbine oil degradation and wear debris accumulation in real time. Defense applications include wear particle trending in armored vehicle transmissions, filtration efficiency testing of NBC filters, and fuel purity verification for missile guidance systems. In semiconductor manufacturing, it quantifies sub-100 nm contaminants in CMP slurries and ultrapure rinse water. Pharmaceutical users deploy it for particulate monitoring in sterile filling lines and final container inspection. Additional use cases span wind turbine gearbox oil health management, marine engine lube oil surveillance, hydraulic system commissioning verification, and R&D-level evaluation of filter media, additive packages, and synthetic base stocks.
