Checkline DT-100 [DT-105A] Digital Contact Tachometer with LCD Display and 6" Circumference Wheel

Checkline DT-100 [DT-105A] Digital Contact Tachometer with LCD Display and 6" Circumference Wheel
Checkline DT-105A, DT-107A and DT-107A-12 contact tachometers accurately measure rotational and surface speed, as well as length. A built-in selector switch permits the user to display readings
in a wide variety of engineering units.

The 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.
