The HZDY-1000 automatic polishing dropper is a high-end device that uses human-machine control technology, outputs by a precise peristaltic pump, and displays and controls the automatic output interval and automatic output capacity on a touch screen, so as to achieve the purpose of timing, constant speed, quantitative and uniform output of polishing liquid. The motor uses a 24V DC brushed motor, which has a long service life and can completely replace manual dripping, freeing your hands. This machine can adapt to the output of various suspensions and can be used independently on various polishing equipment. It is simple to operate, simple in appearance, and safe to use. It is the best supporting equipment for metallographic sample preparation. In the metallographic laboratory, the pre-grinding and polishing grinding of the sample are multiple indispensable procedures during the preparation of the metallographic sample. The polishing suspension needs to be added during the polishing process. The design of this dropper is to facilitate the automatic addition and automatic titration of the polishing liquid. It is especially suitable for metallographic laboratories in factories, colleges and universities, and scientific research institutions. It is an excellent equipment for metallographic sample corrosion.
