The Shimpo DT-105A-S12 and DT-107A-S12 are accurate, microprocessor-controlled hand tachometers that are great for all rotational, linear, and surface speed and length measurements. They are ruggedly constructed with high-quality components for superior performance and durability. Packed with features like expanded memory storage, added length functions, free NIST certificates, and many standard accessories, these tachometers are a great value. This tachometer also comes with a 12" circumference wheel, allowing it to provide more accurate measurements than the 6" wheel which comes standard with the DT-105A and DT-107A tachometers.Read More...
