The XG609 fully automatic kinematic viscosity tester is designed and manufactured according to GB/T265 and ASTM D445 standards. This instrument adopts fiber optic conduction detection method, which is superior to ordinary photoelectric tube detection method. Measure the kinematic viscosity of transparent and opaque liquids including crude oil, light and heavy fuel oil, lubricating oil, additives, and waste oil. It can be widely used in departments such as power, petroleum, chemical, railway, aviation, commercial inspection, and scientific research.
