Possessing the same sophisticated features and accessories as our
renowned DT-105A/107A models, the DT-105A-S12 and DT-107A-S12
tachometers provide outstanding accuracy in measuring speed and direct
linear length via a 12” wheel. The larger wheel rotates more slowly than a standard
6” wheel, thus enabling confident and safe high speed measurement.
Superior accuracy in high speed measurement
