Purpose

The universal length measuring instrument is a length measuring instrument used for absolute measurement and relative measurement. It applies the Abbe comparison principle and adopts a high-precision measurement system, so it has a high measurement accuracy. The instrument is mainly used in the metal processing industry, especially in the measurement rooms and professional measurement departments of various levels of enterprises such as machine manufacturing, bearing manufacturing, measuring tool manufacturing, precision tool manufacturing and instrument manufacturing.

It is different from the traditional universal length measuring instrument: JDY-6 data processing type universal length measuring instrument adopts grating digital display technology, which is a high-tech product integrating light, machine and electricity (calculation), which greatly improves the accuracy of the instrument. sex and productivity. A variety of accessories have been added.

The main measurement objects are:

1. Shafts, holes, plug gauges, ring gauges, calipers, gauge rods, cones, smooth cylindrical parts, lower grade gauge blocks, parts with parallel planes, etc.

2. Pitch diameter of internal thread, external thread, thread ring gauge and thread plug gauge. Micrometers above 25mm, dial indicators, dial indicators, rod-carrying dial indicators, rod-carrying dial indicators, inner diameter indicators, etc.

JDY-6 universal length measuring instrument is equipped with a data processing system, which includes: computer, data processing software, digital display hard card, and the measurement results can be output by a printer.
