NOVELTY - The utility model claims an engine lubricating oil test device based on graphene modified lubricating oil, comprising a processor main body, said processor main body rear end outer surface is fixed with a detachable board main body, the processor front end outer surface is fixed with a controller and the fixed frame, and one side of fixing frame is located on the controller. This utility model claims a engine lubricating oil test device based on graphene modified lubricating oil, comprising a sensor carrier, chuck and the movable pin, capable of detecting the lubricating oil is more complete, and performing pre-processing before detecting the lubricating oil through the processor, by changing the different sensors on a sensor carrier, the different detection, more comprehensive and convenient and fast, and can fast disassemble the processor main body, to timely repair, but also more convenient for replacing the sensor carrier. for the sensor carrier to different detecting and repairing, bring better use foreground.
