SJ3100 Electric Dial Indicator Testing Machine


SJ3100 is an electric measuring instrument by using the newest linear encoder system and imported servo motor. In accordance with a variety of regulations and standards, it measures micrometer dial indicators, dial test indicators, dial bore
indicators. The system processes the measured data automatically according to selected standard, finally generates
test report.


1. A servo motor drives measuring spindle to travel accurately, without manual adjustment by hand wheel.

2. Powerful software automatically processes and qualifies the measured data, finally generates test result.

3. Timely update the software against the newest regulations and standards.
