Product Description

High efficiency Vertical Projection Optical Optimeter (JD3)JD3 Vertical Projection Optimeter


PURPOSE
The Projection Optimeter is a high precision length-measuring instrument by comparing measures. It is extensively used to measure grade four and five of standard gauge block (JD20 may measure grade three and four of standard gauge block) and precision parts (as steel ball, roller column, precision parts of ladder shaped etc. ) for external dimensions.

Features:
Characteristics
The instrument can drive 5-grade block gauges.
It can be used for the verification of high-precision plain plug gauges, thread plug gauges and precision sphere diameters.
It is equipped with various worktables, convenient for replacement, in accordance with parts of different shapes.
