Particle monitor for oil condition monitoring is a product category rather than a specific brand, commonly used in industrial maintenance to assess the health of lubricating oils by detecting contaminants. Companies like Parker Hannifin (USA) and Spectro Scientific (a subsidiary of AMETEK, USA) offer such solutions. These monitors serve industries like manufacturing, energy, and transportation, providing real-time data on particle counts, size distribution, and oil degradation to prevent equipment failure. Key products include portable analyzers and inline sensors, integrating with predictive maintenance systems.
