Checkline DT-105A Digital Contact Tachometer with LCD Display and 6" Circumference Wheel

Accurately measure rotational and surface speed, as well as length. Built-in selector switch permits the user to display readings in a wide variety of engineering units.

The DT-105A-12 and DT-107A-12 includes a 12" circumference measuring wheel which is offered for safer and easier surface speed measurement by keeping the users hand farther from the moving surface and slowing down the rotational speed.
