YJS150 Oil particle counter is an instrument for detecting the quantity and size distribution of solid particle contaminants in oil fluids, counting and categorizing particles in oil fluids by optical, electrical or microscopic techniques, widely used in quality monitoring of lubricating oils, hydraulic oils, fuel oils and other oil fluids.

1.Indicators that can be monitored by the oil liquid particle counter

Particle number: the total number of particles per unit volume of oil liquid (e.g., the number of particles per milliliter).

Particle Size Distribution: Categorized particle counts according to different particle size ranges (e.g. 4μm, 6μm, 14μm, etc.).

Contamination level: assess the contamination level of the fluid according to standards such as ISO 4406, NAS 1638, etc.

Wear particle analysis: Identify metallic or non-metallic wear particles to assist in determining the type of equipment wear (e.g. normal wear, abnormal wear)

2.Why does lubricating oil analysis require the Yateks YJS150 oil particle counter?

（1）Assess fluid cleanliness

Particle contamination accelerates equipment wear and the counter quantifies the level of contamination to ensure that the fluid meets standards (e.g. ISO 4406 18/16/13 for hydraulic systems).

（2）Predict equipment failure

An abnormal increase in particles may indicate early wear or failure of components such as bearings and gears.

（3）Optimize maintenance intervals

Reduce maintenance costs by monitoring contamination trends and scientifically planning oil changes or filtration.

（4）Verify filtration effectiveness

Check the performance of oil filtration equipment to ensure it effectively removes particulate contaminants.

3.Equipment that can be monitored by an oil particle counter

（1）Hydraulic systems

e.g., hydraulic oil in construction machinery, injection molding machines, machine tools.

（2）Lubrication systems

including engines, gearboxes, compressors, wind turbine gearboxes, etc.

（3）Fuel system

fuel pollution monitoring of diesel engines, gas turbines.

（4）Aerospace

aircraft hydraulic oil, engine lubricant cleanliness control.

Industrial critical equipment: such as turbines, bearings, pumps and other equipment that require high cleanliness oil.

4.Summary

Oil Particle Counter is a core tool for fluid monitoring, helping users prevent equipment failure, extend fluid life, and reduce maintenance costs by quantifying particle contamination and wear status in real time, especially for hydraulic and lubrication systems with strict cleanliness requirements.
