High-Precision type Inner/Outer Diameter Measuring Heads

It can measure Inner diameter or Outer diameter with high accuracy.

High-Precision JET

High-precision JET is an inner and outer diameter measurement JET that improves the repeatability accuracy by replacing a conventional one diameter measurement nozzle and adopting the multiway measurement nozzle. Used in combination with an A/E converter. Supports supply pressure of 0.25 MPa. We can recommend stand for your measuring purpose.

Master for High-precision

The high-precision JET is used with a set of two masters; one for the upper limit and another for the lower limit.
Upper limit and lower limit masters are changed to adjust magnification.
A middle limit master is also available when required.
