Shimpo Contact Style Digital Handheld Tachometer DT-105A & DT-107A

Shimpo Tachometer offers direct length measurement

Our Shimpo DT-105A and DT-107A Tachometers are accurate, microprocessor-controlled hand tachometers that are great for all rotational, linear, and surface speed and length measurements.

These tachometers are constructed with the highest quality components for optimal performance and durability. Packed with useful features like expanded memory storage, added length functions, free NIST certificates, and many accessories to use along with them, these tachometers are necessary tools at a great value. DT-105A and DT-107A include a standard 6" wheel, DT-105A-S12 and DT-107A-S12 include a standard 12" wheel, DT-105A-12CBL and DT-107A-12CBL include a 12" cable wheel and DT-105A-12KMW and DT-107A-12KMW include a 12" knurled aluminum wheel.

There are two models to choose from, the DT-105A LCD display or the DT-107A LED display. The Shimpo DT-105A tachometer has a slightly larger display and longer battery life as compared to the Shimpo DT-107A tachometer. The display on each tachometer spans five digits.

LCD Display [DT-105A] 0.47" (12 mm) H Flashing "LO BAT" battery indicator 65 hr battery life
LED Display [DT-107A] 0.4" (10 mm) H "B" low battery indicator 40 hr battery life


Choose the standard 6" circumference measuring wheel for your Shimpo DT-105A or DT-107A Tachometer, or upgrade to a 12" circumference measuring wheel. The 12" wheel rotates more slowly than the 6" wheel, allowing you to safely and reliably register high speeds.

Includes standard 6" wheel
Includes standard 12" wheel
Includes 12" cable wheel for use with extruded tubing, elevator cables, and cable/wire reels
Includes 12" knurled aluminum wheel for use with fabrics, conveyor belts, rubber, coarse weave, wood, foam, insulation, and belts
