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 lighter in weight. Constructed of
strengthened high impact plastic, these rugged units are excep-
tionally reliable and withstand the same harsh conditions as more
expensive units. Employing its unique phase shifting feature, the DT-
725 "freezes" rotating or reciprocating machinery for visual inspec-
tion 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 pre-
ventive maintenance of automated motion equipment. Units can be
ordered separately or as a convenient kit.
To mount the strobe on a tripod (or any other mounting surface), use
screw 1/4 - 20unc, length 8mm or shorter, for the tripod screw hole
on the bottom.
