| The World’s Finest Tachometers Are Now Even Better | |
|
Shimpo’s microprocessor technology has heralded a superior standard in tachometer accuracy and capabilities for measuring and recording rotational/linear/surface speeds and total length. Offering unprecedented confidence, the DT-105 A and DT-107 A 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 units feature expanded memory storage, added length functions, free N.I.S.T. certificate and many standard accessories. Available with LED or LCD displays. |
