DT-107A (LED) Tachometer

DT-107ASeries DT-107A (LED) Contact Tachometers

The Series DT-107A Tachometer with microprocessor technology has heralded a superior standard in tachometer accuracy and capabilities for measuring and recording speeds of rotational, linear and surface plus total length. Offering unprecedented confidence, the DT-107A battery-operated tachometers feature the same rugged, high quality components that have made them the benchmark in the industry. These user-friendly, value-packed units feature memory storage; quick adjustment units knob; length functions; retrieval of last, maximum and minimum values; plus each unit comes standard with a free N.I.S.T. certificate. Units are available with an LCD or vibrant red LED display.

Incorporating the precise technology and user-friendly functions as the DT-107A, the DT-107A-S12 provides an exceptional accuracy in measuring speed and length via its 12” wheel. The larger wheel rotates more slowly than a standard 6” wheel, enabling reliable and safe registration of high speeds.
