LCD Display Contact Tachometer, 12″ Circumference Measuring 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. LCD model appropriate for environments with natural light, sunlight, etc. and for longer battery life.

The DT-105A-S12 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.
Features: – 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 model appropriate for use in sunlight- Longer battery life- Kit includes 12 inch 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.
