The DT-725 portable, light weight stroboscope
with rechargeable battery possess many of the same
features as the famous DT-300 Series Stroboscopes, but are light-
er in weight. Constructed of strengthened high impact plastic,
these rugged units are exceptionally reliable and withstand the
same harsh conditions as more expensive units. Employing its
unique phase shifting feature, the DT-725 “freezes” rotating or re-
ciprocating machinery for visual inspection of covered gear teeth,
shafts, oil/fuel/ink injector patterns, and print media; all without
stopping production.
These features make the DT-725 ideal for quality inspection and
preventive maintenance of automated motion equipment. Units
can be ordered separately or as a convenient kit.
