Micrometers are basically precision measurement instruments used in mechanical engineering arena. These digital instruments consist of primary scale on their sleeve and secondary scale which is located on their thimble. Provided instruments are used for determining groove dimension of shafts etc. Large digital display screen of these instruments promote convenient reading of measured result. These instruments can convert measured data from metric to inch. Measurement spindle of these Micrometers has been hardened and ground for prolonged service life. Heat insulated handle of these precision instruments is expansion proof. Their two function on-off power buttons ensure about their high automation degree. Long life span of their batteries ensures their uninterrupted operation. Plastic components of these instruments are oil protected for longer working life.
