BY TYPE

• Handheld Particle Counters: Handheld particle counters are compact instruments designed for portable contamination monitoring across cleanrooms, laboratories, manufacturing facilities, HVAC systems, and field environments. Typical handheld airborne models measure particles from approximately 0.3 µm to 10 µm and commonly provide 6 particle-size channels, including 0.3 µm, 0.5 µm, 1.0 µm, 3.0 µm, 5.0 µm, and 10.0 µm. Sampling flow rates frequently include 2.83 L/min, equivalent to 0.1 CFM, while rechargeable batteries support several hours of field operation. Handheld particle counters are particularly suitable for spot checks, cleanroom certification support, filter testing, indoor-air investigations, and contamination troubleshooting. 
• Desktop Particle Counters: Desktop particle counters are laboratory-oriented instruments designed for higher-volume, repeatable particle analysis of air, liquids, chemicals, oils, and other controlled samples. Depending on instrument configuration, desktop systems can measure particles below 1 µm and classify contamination across 6 or more size channels. These systems are widely deployed in pharmaceutical laboratories, semiconductor manufacturing, research centers, quality-control laboratories, automotive facilities, and industrial contamination-analysis departments. Compared with handheld devices, desktop instruments generally provide larger sample-processing capacity, enhanced data storage, automated analysis, and more extensive connectivity. 
• In-line Particle Counters: In-line particle counters are permanently or semi-permanently integrated into production lines, hydraulic circuits, lubrication systems, process-fluid networks, and contamination-control systems to provide continuous particle monitoring. Unlike periodic manual sampling, an in-line instrument can collect measurements 24 hours per day and identify changes in contamination levels as operating conditions vary. Liquid systems commonly monitor particle sizes around 4 µm, 6 µm, and 14 µm, particularly for hydraulic and lubrication applications. Continuous measurement enables operators to detect filter deterioration, component wear, contamination ingress, and abnormal process conditions without waiting for laboratory results. 

BY APPLICATION

• Construction Machinery: Construction machinery is a significant application segment for particle counters because excavators, loaders, bulldozers, cranes, graders, and other heavy equipment depend on hydraulic and lubrication systems operating under demanding conditions. Modern hydraulic systems can operate above 300 bar, where fine particulate contamination can accelerate wear in pumps, valves, bearings, and cylinders. Particle counters typically evaluate hydraulic-fluid contamination at 4 µm, 6 µm, and 14 µm size thresholds. Handheld instruments enable technicians to perform field inspections, while in-line particle counters provide continuous monitoring during equipment operation. 
• Petrochemical & Chemical Industry: Petrochemical and chemical facilities use particle counters for monitoring hydraulic fluids, lubricating oils, fuels, specialty chemicals, and other process liquids. Large industrial complexes can operate hundreds or thousands of pumps, compressors, turbines, valves, and hydraulic systems, creating extensive contamination-monitoring requirements. Liquid particle counters commonly classify particles at 4 µm, 6 µm, and 14 µm, while advanced instruments can detect particles across wider size ranges exceeding 100 µm. In-line particle counters are particularly valuable in plants operating 24 hours per day, as continuous measurement helps detect sudden contamination increases, 
• Mining Industry: Mining operations require particle counters because excavators, haul trucks, drilling machines, crushers, loaders, conveyors, and mineral-processing equipment operate in environments with substantial dust exposure. Large mining haul trucks can carry payloads exceeding 300 tonnes, while heavy hydraulic equipment frequently operates at pressures above 300 bar. Dust and abrasive particles entering hydraulic or lubrication systems can increase component wear and reduce filtration effectiveness. Particle counters monitor contamination at standardized thresholds such as 4 µm, 6 µm, and 14 µm, allowing maintenance teams to assess oil cleanliness directly at mining locations. 
• Others: Other particle counter applications include power generation, automotive manufacturing, aerospace, marine equipment, industrial manufacturing, agriculture, transportation, wind energy, research laboratories, and hydraulic-system maintenance. Power plants use particle counters to monitor turbine oils and hydraulic fluids, while automotive and aerospace manufacturers apply particle analysis during component cleanliness testing and assembly operations. Liquid instruments commonly monitor particles at 4 µm, 6 µm, and 14 µm, with certain systems capable of detecting contamination above 100 µm. Wind turbines with capacities exceeding 10 MW contain lubrication and hydraulic systems where contamination monitoring can support equipment maintenance.
