Oil Particle Counters
Oil Particle Counters – QualiOPC™ & ToronOPC™ Series
Oil Particle Counter systems are designed to support laboratories and maintenance teams in measuring solid contamination levels in oils and other industrial fluids. These instruments enable accurate tracking of fluid cleanliness, early detection of abnormal wear, and reliable condition monitoring for critical equipment. The QualiOPC™ series includes desktop, portable, online, laboratory, and sensor-based configurations, giving flexibility for field service operations, plant monitoring environments, and laboratory analysis workflows.
This product range is suitable for a wide variety of fluids, including hydraulic oil, lubricating oil, transformer oil, turbine oil, gear oil, engine oil, aviation kerosene, water-based hydraulic fluids, organic liquids, and polymer solutions. The systems use light-blocking measurement technology, semiconductor laser detection, and integrated cleanliness coding features to deliver standardized contamination reporting aligned with recognized industry practices.
The QualiOPC™ and ToronOPC™ series represents a complete lineup of Oil Particle Counters designed for both industrial and laboratory use. The range includes desktop units for routine laboratory analysis, portable devices for field inspections, online particle counters for continuous system monitoring, laboratory-grade platforms for high-viscosity fluid testing, and sensor modules for seamless integration into automated monitoring systems.
These systems and sensor solutions are used to determine particle size distribution and particle concentration within fluid samples, helping users evaluate oil cleanliness levels, contamination severity, and equipment health trends over time. Depending on the configuration, the series supports offline bottle sampling, online real-time monitoring, high-pressure sampling options, vacuum-based sample handling, and compatibility with broader oil analysis and condition monitoring systems.
Applications of Oil Particle Counter Systems
Hydraulic and Lubricating Oil Monitoring
The complete range is suitable for hydraulic and lubricating oil contamination measurement. It supports maintenance teams in monitoring fluid cleanliness levels, identifying wear-related particles at an early stage, and improving maintenance scheduling and fluid replacement planning.
Transformer and Insulating Oil Testing
Selected models in the series are designed for transformer and insulating oil evaluation. This makes the range highly relevant for utility providers and industrial operators that require accurate insight into dielectric fluid condition and contamination levels.
Aerospace, Power Generation, Transportation, and Heavy Industry
The system lineup is designed for use across military, aerospace, electric power, rail, marine, mining, heavy machinery, and transportation sectors. These industries rely on fluid cleanliness monitoring to reduce contamination-driven failures and improve long-term equipment reliability.
Continuous Online Contamination Monitoring
Online configurations are suitable for real-time monitoring of particle contamination in hydraulic and lubrication systems. This allows continuous tracking of oil condition during operation, reducing dependency on periodic manual sampling.
Laboratory Analysis and System Integration
The QualiOPC™ VES model is designed for laboratory-based particle contamination analysis, particularly for complex fluid types. In addition, the QualiOPC™ 60 sensor is built for integration with portable, online, and laboratory systems, extending the range into modular and system-level contamination monitoring solutions.
