DT-107A-12-EXH With Extended Handle
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.
- Includes NIST Traceable Calibration Certificate
- Built-in memory for last, maximum, minimum and 10 separate readings
- Rugged cast aluminum housing
- Includes Traceable calibration Certificate
- LCD Version for use in sunlight and for longest battery life (DT-105A)
- LED version for use in poorly lit or dark environments (DT-107A)
Optional 12" Wheel for Large Diameter Cables, Tapes & Bands
All models are supplied as a complete kit including 6" (or optional 12") circumference surface speed wheel, two cone tip adapters, funnel tip adapter, shaft extension, two AA batteries, NIST traceable calibration certificate and an operating instruction manual - all supplied in a foam-fitted carrying case.
The DT-105A-12 and DT-107A-12 includes a 12" circumference measuring wheel instead of the 6 inch one
