The PAMAS S40 is a portable particle counting system for oil-based liquids like hydraulic and lubricating oil. A wear resistant ceramic piston pump guarantees a constant flow. With a simple-to-use touch screen user interface, operation is easy and intuitive. The system is equipped with an integrated battery for up to three hours operation and a data storage of up to 4000 measurements. The system can be used for batch sampling and online measurements. Additional accessories are available.
