JDS-1 Vertical Contact InterferometerDetailed product description：

Product Introduction:
The vertical contact interferometer JDS-1 is a vertical precision length measuring instrument that uses gauge blocks or standard parts for high-precision comparison. It is mainly used for block gauges below 150mm, and can also be used for high-precision measurement of length and outer diameter. It is one of the basic length measuring instruments in various measurement chambers.
