Photo/Contact Tachometer
One meter provides precise RPM measurements with or without contact
Multi-Functional: New patented design incorporates both a
photo and contact tachometer into one precision instrument
Wide Measuring Range: From 0.5 to 20,000 RPM in contact mode from
5 to 99,999 RPM in photo mode. Linear surface speed measurements
are 0.2 to 6560 ft/min. or 0.05 to 1999.9 m/min
Memory Recall Button: Automatically holds last reading for
5 minutes and recalls minimum and maximum readings
Microcomputer LSI Circuitry: Provides accuracy to 0.05%
and permits readings to a resolution of 0.1 RPM in
either photo or contact mode
Accessories Included: 3" wheel, 1 cone adaptor,
1 cone tip, 1 funnel cone, 1 funnel tip,
one sheet of tabs, carrying case
