Features
Dual function unit with both contact and non-contact capabilities
Provides fast and accurate RPM measurements of rotating objects and surface speed measurements m/min (meter per min) and ft/min (feet per min)
Internal memory holds last reading for 5 mins and recalls min/max and last value
LCD Display reverses depending on measurement mode
