The presence of particulate contamination in a liquid system is acknowledged to be a major factor governing the life and reliability of that system. The presence of particles residual from the manufacturing and assembly processes will cause a substantial increase in the wear rates to the system during the initial run-up and early life, and may even cause catastrophic failures.

In order to achieve reliable performance of components and system, control over the amount of particles introduced during the build phase is necessary, and measurement of particulate contaminants is the basis of control. The FPAS series of equipment's have been developed to fulfill the requirements of the automotive industry. This, image analysis based equipment, measures the cleanliness level of the components by particulate counting. The results are reported as per international ISO standard 1S0 16232.
