Oil Particle Counter

Product Introduction

The HD-YT20 Oil Particle Counter is developed in accordance with GB/T 18854-2002 (ISO 11171-1999) and other standards. It adopts the light-blocking (light-extinction) counting principle and fully complies with the corresponding national military standards, national standards and international standards. It provides fast, accurate, reliable and repeatable detection results and complete contamination monitoring and analysis reports, and is suitable for detecting the particle contamination degree of hydraulic oil, lubricating oil, fire-resistant oil, insulating oil and turbine oil. It can be widely used in aviation, aerospace, electric power, petroleum, chemical engineering, transportation, ports, metallurgy, machinery, automobile manufacturing and other fields.

Main Features

• Adopts the light-blocking (light-extinction) counting principle specified by the International Hydraulic Standards Committee.
• High-precision laser sensor with wide test range, stable performance, low noise and high resolution.
• Uses high-pressure syringe pump sampling; the sampling volume can be set by the user, with stable injection speed and high sampling accuracy.
• Positive and negative pressure combined injection system realizes sample degassing and is suitable for testing samples of different viscosities.
• Built-in pressure sensor allows the pressure value to be set directly and automatically determines the air pressure in the chamber to ensure safety.
• Built-in air purification system ensures that testing is not contaminated.
• Built-in SAE4059E, SAE4059F, SAE4059F-CPC, NAS1638, ISO4406, GB/T14039, GJB-420A, GJB-420B, GOST17216-71, DL/T1096, SAE749D, JBT9737.1, QC/T29104-201, DL-T432-2018, HH005-2018 and more than ten other common standards; supports arbitrarily adding user-defined standards with no upper limit on the number, and the required standards can be set according to customer needs.
• Built-in data analysis system; one test can give the test data and contamination degree grade of all standards.
• Built-in multiple calibration curves compatible with all common domestic and international standards for single-channel or multi-channel fully automatic calibration.
• Particle size can be set arbitrarily; nearly 10,000 particle sizes are built in for particle size analysis.
• Various sampling containers such as standard sampling bottles or cups can be used to meet the testing requirements of different industries.
• Optional viscosity, dielectric constant, moisture and temperature sensor modules can be added to realize multi-parameter testing.
• Windows operating interface with built-in database and unlimited data storage; retrieval and query can be performed by test standard, sample name, sample batch number, tester, test time and many other ways.
• Multi-level account permission management with separately settable account permissions and support for digital signatures.
• One control system supports multiple sensor settings; the system control software can be installed on a tablet computer, notebook computer or desktop computer.
• Test results can be printed with a micro or desktop printer and can be exported in PDF, Excel and other formats and transmitted via USB, Wi-Fi, etc.
