KLD-B adopts the principle of laser blockage method (laser shading method) to detect the size and number of solid particles in the oil. Based on the measurement, it does the analysis and displays the oil contamination level in various standards (e.g NAS1638, ISO4406, GJB, etc) so as to help the operator be aware of the potential risks and avoid any evitable wear of parts.It can be widely applied to various kinds of oil, such hydraulic oil, lubricating oil, gearbox oil, insulating oil (transformer oil), etc. Highlights: 1. High precision. Adopting the principle of laser blockage method (laser shading method) which is the most efficient method to count the number of particles in liquid. Equipped with high-quality Germany-made transducer, which ensures the precision of counting. 2. Two ways of measurement. Both on-line and sampling measurement are available. 3. Able to display the measurement result in the form of NAS1638, ISO4406, GJB by means of both digits and diagrams. 4. Equipped with big touch screen. Easy for operation and efficient for display. 5. Built-in PC. No need connecting the instrument to another computer, operator could look up the data by various standards such as location, time, operator name, etc, or transfer the data via USB connection. 6. Printer internally installed. Able to print out the measurement result within 45 sec. 7. Lithium battery installed. Suitable for outdoor use. 8. Large data storage volume.160G hard disk. 9. Suitcase design. Light and small. Easy to take along.
