DT-107A (LED MODEL)
DT-107A-12 (LED MODEL with 12" Circumf. Wheel) 0.10 - 25,000 RPM
The DT-105A & DT107A 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-105A-12 and DT-107A-12 include 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.
Optional 12" Wheel for Large Diameter Cables, Tapes & Bands
