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.

|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|
