application

A length gauge is a type of length measuring instrument used for absolute and relative measurements, widely used in metrology rooms and various professional metrology appraisal departments of enterprises such as mechanical manufacturing, tool and measuring tool manufacturing, and instrument manufacturing. The JD36 high-precision universal length measuring instrument is a high-tech product that integrates optics, mechanics, and electronics (computing), greatly improving the accuracy and operational efficiency of the instrument. At the same time, various attachments have been added to enhance its versatility.

Its main measurement objects include:

a. Smooth cylindrical parts (shafts, holes, plug gauges, ring gauges, etc.)

b. The pitch diameter of internal and external threads, thread plug gauges, and thread ring gauges

c. Parts with parallel planes (calipers, measuring rods, lower grade measuring blocks)

Technical Parameter
