Intelligent tester of magnetic lubricating oil nano granule space distribution rule

The invention belongs to a testing instrument for nano liquid functional materials. In a magnetic lubricant nano particle spatial distribution intelligent tester, a base thereof is provided with a gradient magnetic system and a testing system side by side; the gradient magnetic system is that the lower magnetic is fixed on the base by a magnetism isolating cylinder and is provided with an electromagnet system which is provided with a cup base; the lower magnetic is connected with an upper magnetic ring by four field yokes. The center of the upper magnetic is opened with a hole; the testing system is that a sensor and a data acquisition instrument are arranged on an instrument platform of a lift control instrument; the sensor is connected with a measuring ball by a sling; the measuring ball is arranged in a magnetic lubricant cup to be tested; the cup passes through the hole of the upper magnetic ring and is arranged in the cup base. The instrument has reasonable structure, simple operation, remarkable experim
