Corditest specification:

Measuring instruments for internal thread from 3mm - 560mm nominal diameter
The ball bearings are isolated from the environment, making the instrument well suited for production environment
Adapted for gauges / sensors with 8mm diameter shaft
Uses thread studs & thread rollers
For all national and international standards as well as special threads
Friction-free movement with ball bearings provides high precision measurement
Can be used handheld as well as table unit
Adjustable measuring force
Durable design

Thread measuring studs consist of two segments of studs that have measuring wire, these two studs hit the object in the axis along with the thread and cover a large part of the thread simultaneously.
Calibration of the instrument is done against a master thread ring.

From a diameter of approx. 31 mm thread, measuring rollers can be used instead.
The measuring rollers must be changed if the thread pitch changes.
