The cleanliness of components, parts, and fluids is at the centre of the manufacturing process. Meeting high standards for counting, analysing, and classifying the often micron-sized contaminant and foreign particles is important for all processes: development, manufacturing, production, and quality control of the final product.
International and national directives describe the methods and documentation requirements for determining particle contamination on essential machined parts since these particles directly impact the lifespan of parts and components. Current standards demand detailed information about the nature of the contamination, such as the number of particles, particle size distribution, and particle characteristic.
The system complies with NAS 1638, ISO 4406, ISO 4407, SAE AS 4059 standards. It also enables users to produce company-specific classification settings.

Particulate Contamination Analysis of Hydraulic Oil Using a Turnkey Cleanliness Inspector.
The cleanliness analysis using microscope can overcome the shortcomings of these other methods to deliver the precision needed for particulate contamination in hydraulic oil.
Built with a high-performance industrial microscope can acquire accurate data on the size and shape of individual contaminant particulates.
Its unique optical system can detect both reflective and non-reflective particles. As a result, metal and non-metal contamination can be classified in a single scan.
