What are particle counters used for?

• Monitoring the purity degree of oil in hydraulic systems in order to increase their reliability.
• Testing of virgin oils for impurities (cleanliness class of virgin oil according to NAS between 10 – 12 according to ISO 18/15/12 to 23/20/18
• Where guaranty requirements have to be met and where the cleanliness of the oil has to be checked on the customer sit.
• To obtain an economic, safe and reliable indication of the oil's cleanliness
• To obtain a quantitative indication of the oil's cleanliness.

Where are particle counters used?

• In machine and hydraulic equipment manufactures
• In after-sales and maintenance departments
• In companies repairing and maintaining hydraulic equipment
• By hydraulic machines and equipment operators, hydro-electric plants, etc.
• Anywhere, where particle counting has to be carried out in a simple and economic way.
• Priced at less than CHF 5000.- (multi-channel measuring systems approximately CHF 25‘000.-)

Schako II particle counter features

• By using the light blockade principle, the counter determines the number of particles between 6 and 14 µm (2 channels) found in 100 ml oil within 1 minute
• On-line measuring in high-pressure systems between 20 and 315 bar
• On-line measuring in low-pressure systems between 10 and 20 bar
• Measuring at pressures below 10 bar (tank) by using a booster pump
• Output data according ISO (converted according to NAS)
• Including filter (150 µm) protecting the measuring unit
• Miniature hydraulic connectors.

What can the Schako II particle provide for and what can we do with it?

• The composition of solid matters regarding particle size distribution is quite constant
• The presence of 6 and 14 µm particles give good indication about the cleanliness of the analysed oil
• The Schako particle counter cannot be used for determining filtering efficiencies which needs at least a 3-channel measurement.
