JD22A Length measuring instrumentDetailed product description：

Product Features

Adopting advanced grating sensor technology for digital display of measurement data;
The measuring spindle adopts a square axis design, which has good linearity and stable performance during operation;
The instrument design conforms to the Abbe principle, with no Abbe error and high measurement accuracy;
The spindle movement can be measured automatically or manually, which is convenient for measuring large quantities of workpieces and has high work efficiency.

Product Use

A digital vertical length gauge is a length measuring instrument that combines precision machinery, optical systems, and electrical components. This instrument is used for direct measurement and comparative measurement of part dimensions, with the following scope of use:
external dimensions
Measurement of parallel plane test pieces, such as gauge blocks;
Measurement of spherical flat objects, such as measuring rods and steel balls;
Measurement of a cylindrical surface specimen, such as a cylinder.
inner dimensions
Measurement of parallel plane test pieces, such as card boards;
Measurement of aperture, such as ring gauge.
Thread
Measurement of the pitch diameter of internal and external threads.
