application

The JD25-H universal length gauge is a length measuring instrument used for absolute and relative measurements. Due to its precise application of the Abbe comparison principle and high-precision measurement system, it has high measurement accuracy. This instrument is mainly used in the metal processing industry, especially in the metrology rooms and professional metrology departments of enterprises such as machine manufacturing, tool and measuring tool manufacturing, and instrument manufacturing. Unlike traditional universal length measuring instruments, the JD25-H data processing universal length measuring instrument adopts grating digital display technology, which is a high-tech product integrating optics, mechanics, electronics, and computing, greatly improving the accuracy and operational efficiency of the instrument. At the same time, various accessories have been added, which can be combined to achieve some special measurements and improve 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, measuring blocks).
