Oil Particle Counters
Oil Particle Counter systems help laboratories and maintenance teams measure solid particle contamination in oils and related fluids so they can track cleanliness, identify abnormal wear, and support fluid condition monitoring. The QualiOPC™ lineup covers desktop, portable, online, laboratory, and sensor-based configurations for users who need particle counting across field service, plant monitoring, and lab-based analysis workflows.
This product family is designed for hydraulic oil, lubricating oil, transformer oil, turbine oil, gear oil, engine oil, aviation kerosene, water-based hydraulic fluids, organic liquids, and polymer solutions. Across the range, the systems use the light-blocking method, semiconductor laser technology, and built-in cleanliness coding support to help users report contamination results under recognized industry frameworks.
The QualiOPC™ and ToronOPC™ series is a line of Oil Particle Counter products built for liquid contamination analysis in industrial and laboratory environments. The lineup includes a desktop particle counter for routine lab use, portable models for field testing, online particle counters for continuous monitoring, a laboratory platform for higher-viscosity samples, and a particle counter sensor for system integration.
These instruments and sensor modules are used to measure particle size and particle count in fluid samples so users can assess oil cleanliness, contamination severity, and ongoing equipment condition. Depending on the model, the series supports offline bottle testing, optional online operation, continuous monitoring, high-pressure sampling, water-content measurement, pressure and vacuum sample handling, and integration into larger oil analysis systems.
Applications
Hydraulic and Lubricating Oil Monitoring
The full lineup is suitable for hydraulic and lubricating oil contamination analysis. This helps maintenance teams monitor fluid cleanliness, detect wear-related contamination earlier, and improve service and replacement planning.
Transformer and Insulating Oil Testing
Several models in the family support transformer and insulating oil analysis. This makes the category relevant for utilities and industrial users that need better visibility into dielectric fluid cleanliness.
Aerospace, Power, Transportation, and Heavy Industry
The brochure positions the series for military, aerospace, electric power, rail, marine, mining, heavy equipment, and transportation use. These industries often need fluid cleanliness monitoring to reduce contamination-related failures and improve system reliability.
Online Cleanliness Monitoring
The online models in the range are suited for real-time contamination tracking in hydraulic and lubrication systems. This helps users monitor flowing oil continuously rather than relying only on periodic sample checks.
Laboratory Analysis and System Integration
The QualiOPC™ VES model supports laboratory particle contamination analysis for more challenging liquids, while the QualiOPC™ 60 sensor is intended for integration into portable, online, and laboratory instruments. This broadens the category from standalone instruments to full contamination-monitoring system design.
