Oil Particle Counter

Oil Particle Counter

  • Product Number:LD-YT20
  • Product Difference:Large-screen monitor for detecting particulate contamination in hydraulic oils, lubricating oils, fire-resistant oils, insulating oils, and turbine oils

Product Introduction

The oil particle counter complies with standards such as GB/T18854-2002 (ISO11171-1999). Developed using the optical blockage (light-blocking) counting principle, it fully complies with relevant military standards, national standards, and international standards. It provides rapid, accurate, reliable, and repeatable test results along with comprehensive contamination monitoring analysis reports. Suitable for detecting particle contamination in hydraulic oils, lubricating oils, fire-resistant oils, insulating oils, and turbine oils. Widely applicable in aviation, aerospace, power generation, petroleum, chemical, transportation, port operations, metallurgy, machinery, and automotive manufacturing sectors.

Product Features

  • Employs the specific optical resistance (light-blocking) counting principle established by the International Hydraulic Standards Committee.

  • Built-in air purification system ensures contamination-free testing.

  • High-precision laser sensor with wide measurement range, stable performance, low noise, and high resolution.

  • Optional viscosity, dielectric constant, moisture, and temperature sensor modules enable multi-parameter testing.

  • High-pressure injection pump sampling allows customizable sample volume settings, stable injection speed, and high sampling accuracy.

  • Built-in pressure sensor enables direct pressure value setting and automatically detects chamber air pressure to ensure safety.

  • Includes over a dozen built-in standard tests, supports unlimited custom standard additions, and allows configuration of required standards based on customer needs.

  • Windows-based interface with built-in database and unlimited data storage. Enables retrieval and queries by test standard, sample name, sample batch number, tester, test time, and more.

  • Built-in data analysis system provides comprehensive test data and contamination levels for all standards in a single run.

  • Integrated positive/negative pressure sampling system enables sample degassing, suitable for testing materials of varying viscosities.

  • Built-in multi-calibration curves compatible with all common domestic and international standards, supporting single-channel or multi-channel fully automatic calibration.

  • Supports various sampling containers such as standard vials or cups to meet testing requirements across industries.

  • Allows arbitrary particle size settings with nearly 10,000 built-in particle sizes for convenient particle size analysis.

  • Multi-level account permission management enables separate account rights configuration and supports digital signatures.

  • A single control system supports multiple sensor configurations. System control software can be installed on tablets, laptops, or desktop computers.

  • Test results can be printed using micro or desktop printers, exported in PDF, Excel, and other formats, and transferred via USB, Wi-Fi, or other methods.
