JD25-C Data Processing Universal Length Measuring Instrument

1、 Characteristics:
The base is made of high-quality cast iron, which has undergone long-term natural aging treatment and has good stability. Adopting optimized design to ensure good performance and high accuracy from a structural perspective. The attachments are complete and versatile. Adopting grating digital display technology and using a precision grating ruler as the measuring element. The software is fully functional and can not only correct indication errors, but also automatically correct measurement errors caused by temperature. The software has the function of automatically identifying turning points.

2、 Purpose:
The universal length measuring instrument for data processing is an integrated length measuring instrument that combines optics, mechanics, electronics, and computer technology. In addition to absolute and comparative measurements of the internal and external dimensions of parts, it can also be used to perform various special measurements using the special accessory combinations provided with the instrument. This instrument is mainly used in the mechanical manufacturing industry, tool and measuring tool manufacturing, precision instrument manufacturing, and other metrology appraisal departments and measurement rooms of enterprises at all levels.
Its main measurement objects include:
Smooth cylindrical parts (shafts, holes, plug gauges, ring gauges, etc.)
The pitch diameter of internal thread, external thread, thread plug gauge, and thread ring gauge.
Parts with parallel planes (calipers, measuring rods, lower grade measuring blocks)
