Overview
The PULUODY PLD-0203-16-1 Optical Oil Particle Counter is a high-precision, dual-mode particulate analysis instrument engineered for quantitative assessment of suspended insoluble particles in liquid media—primarily lubricants, aviation fuels, hydraulic fluids (including aggressive phosphate ester formulations), and ultra-pure process solutions. It operates on two complementary optical detection principles: light obscuration (LO), compliant with ISO 11171 and ISO 4402, and multi-angle light scattering (LS), enabling robust discrimination of particle morphology, refractive index contrast, and concentration across a broad dynamic range. Designed for both offline laboratory analysis and inline monitoring (with optional pressure-rated flow cell), the system meets stringent requirements for condition-based maintenance (CBM), military equipment readiness verification, aerospace fluid certification, and pharmaceutical-grade solvent qualification. Its architecture integrates metrologically traceable calibration protocols—including PSL latex sphere validation per ASTM F658-87 and MTD/ISO 11171 reference materials—to ensure inter-laboratory comparability and regulatory defensibility.
Key Features
- 7th-generation dual-laser narrow-beam optical sensor with simultaneous LO/LS signal acquisition for improved particle classification fidelity
- 1000-channel high-resolution sizing matrix, supporting user-defined binning across 16 customizable particle size ranges (e.g., 4–6 µm, 14–25 µm, etc.)
- Configurable measurement range from 0.03 µm to 3000 µm—optimized via modular sensor selection for specific application needs (e.g., sub-micron wear debris vs. macro-contaminant screening)
- Automated self-cleaning cycle post-analysis using programmable reverse-flow rinse protocol, minimizing carryover and operator intervention
- Integrated industrial PC or ruggedized embedded controller with 7-inch color touchscreen interface—no external computer required for routine operation
- Full compliance with international contamination grading standards: ISO 4406:1999/2017, NAS 1638, SAE AS4059F, GJB 420B, and DL/T 432
- Analog and digital I/O interfaces (4–20 mA, 0–5 V, RS232/RS485, MODBUS RTU) for seamless integration into SCADA, CMS, or PLC-based asset health monitoring systems
- Onboard thermal printer and non-volatile memory storing up to 6000 test records (200 full assays), each timestamped and user-annotated
Sample Compatibility & Compliance
The PLD-0203-16-1 accommodates a wide spectrum of challenging fluid matrices without pre-filtration or dilution: aviation turbine fuel (Jet A-1, JP-8), synthetic and mineral-based lubricants, fire-resistant phosphate ester hydraulic fluids (e.g., Skydrol®), transformer oils, glycol-based coolants, and ultrapure water (UPW) used in semiconductor manufacturing. Its pressure-tolerant flow cell (up to 31.5 MPa with integrated regulator) enables direct online sampling from high-pressure hydraulic circuits, gearboxes, and fuel supply lines. All calibration and verification procedures adhere to national and international metrological frameworks—GB/T 18854-2002 (equivalent to ISO 11171), JJG 1061 (Chinese national verification regulation), and ASTM D7619 for field-deployable particle counters. The instrument supports GLP and GMP workflows through password-protected user roles, electronic audit trails, and data integrity safeguards aligned with FDA 21 CFR Part 11 recommendations.
Software & Data Management
The P6.4 Analysis Software Suite—available in both embedded and Windows PC editions—provides comprehensive data acquisition, statistical evaluation, trend analysis, and reporting. It enables real-time visualization of differential and cumulative particle distributions, automatic contamination grade assignment (e.g., ISO Code 18/16/13), and comparative overlay of historical datasets. Raw data exports are supported in CSV, PDF, and XML formats, preserving metadata including calibration status, operator ID, sample ID, environmental conditions, and instrument configuration. Cloud synchronization with the PULUODY Oil Monitoring Platform allows centralized fleet-level analytics, automated alerting upon threshold exceedance (e.g., >1000 particles/mL >4 µm), and remote firmware updates. All software modules undergo periodic validation per IQ/OQ protocols to maintain compliance in regulated environments.

FAQ
Does the PLD-0203-16-1 support real-time online monitoring?
Yes—when equipped with the high-pressure flow cell and optional pressure regulator, it performs continuous inline particle counting at pressures up to 31.5 MPa.
Can the instrument differentiate between metallic wear debris and non-metallic contaminants?
While not a compositional analyzer, its dual-sensor architecture enhances discrimination of high-refractive-index particles (e.g., ferrous debris) versus low-index contaminants (e.g., fibers, oxides) via scattering pattern analysis.
Is calibration traceable to NIST or equivalent national standards?
Calibration uses ISO 11171-compliant MTD dust and PSL spheres certified per ASTM F658-87; full traceability documentation is provided with each calibration kit.
What level of software validation support is available for regulated industries?
IQ/OQ documentation packages, electronic signature implementation guides, and 21 CFR Part 11 configuration templates are available upon request for pharmaceutical and defense contractors.
How is sample viscosity handled during measurement?
The system dynamically compensates for viscosity effects on flow profile and particle transit time; validated operating range extends to 500 mm²/s for online applications and 99 mm²/s for offline benchtop use.
