Specifically designed for conducting advanced test analyses of lubricating oil condition directly on-site. The portable test devices offer easy, quick and accurate measurements of five important oil parameters: water-in-oil content, base number, oil viscosity comparison, salt water and soot contamination. Regular assessment of these parameters gives direct and comprehensive information to ship operators, engineers and users about any occurring changes in the oil condition. Trend monitoring with the LUBE OIL CHECK 5 might help to reduce maintenance expenses as well as to prolong the operating time of the engine system components.
