Reed R7140 Digital Laser Photo / Contact Tachometer

Dual function tachometer features the ability to measure RPM with non-contact (visible light) and contact (ft/min / m/min) measurements quickly and accurately.

• Dual function unit with both contact and non-contact capabilities
• Provides fast and accurate RPM measurements of rotating objects and surface speed measurements MPM (meter per min) and FPM (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
• Includes reflective tape, large and small cone tip adapters, funnel adapter, wheel adapter, batteries, and hard carrying case
