Contact Only Tachometer
The Shimpo Handheld Tachometer accurately measures 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 Shimpo DT-105A - DT-107A Handheld Tachometers includes a 12" (30 cm) 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.
