The DT-105A-S12, DT-107-S12
Contact Tachometers
are superior standards in tachometer accuracy
and capabilities for measuring and recording rotational, linear,
surface speeds and total length via
a 12" wheel.
The larger wheel rotates more slowly than a standard 6" wheel,
thus enabling confident and safe
high speed measurement.
Offering unprecedented confidence, the DT-105A-S12 and
DT-107A-S12 battery-operated tachometers
still feature the same rugged, high quality components that have
made them the benchmark in the industry.
These user-friendly, value-packed tachometers feature expanded
memory storage, added length functions
and many standard accessories. Available with LED or LCD
displays.
