General Information

DT-721 (AC-Powered)
DT-725 (Battery Powered)
40.0 - 12,500 RPM/FPM
and higher using harmonics

The DT-721 and DT-725 Digital Stroboscopes are highly stable, industrial-quality instruments for non-contact RPM measurement as well as for inspection and observation of moving parts by “freezing” or “slowing down” the action.

A “Kit” option is offered for both models which also includes a carrying case and spare flash tube at minimal additional cost.
