Series 2
This is a lightweight one revolution dial indicator that gives you error-free reading.
The Metric One Revolution Dial Indicator offers you the following benefits:
– Limiting the pointer rotation to one revolution eliminates the reading errors that
can occur with other dial indicators that use multiple pointer revolutions for a full
stroke.
– Graduation 0,01mm/ 0,02mm
