Digital Tachometer Laser /Contact RPM

This high quality digital tachometer has wide measuring range and high resolution. Offering high ±0.05% accuracy, instantaneous response time, auto-select test range, low power consumption giving a longer battery life and long detecting distance of up to 500mm or 20 inches (with Laser).Operation is very simple, just apply a reflective mark (included in package) onto the target object, then aim the beam at the mark and RPM will be seen on its 5-digit clear LCD. Wide range of applications include measuring rotating speed of machine, motors, model cars, automotive, trucks, aircraft, light rail vehicles, wheels, lathe for metal or wood cutting work, for HVAC applications to measure fan speed and other application that needed rotational speed measurements.
Feature
Automatically holds last reading for 5 minutes and recalls minimum and maximum readings.
Characters on the 5-digit display reverse direction depending on which measurement mode you are in.
Microcomputer LSI circuitry provides accuracy to 0.05% and permits readings to a resolution of 0.1 RPM in either photo or contact mode.
ABS plastic housing assures years of maintenance free performance.
Highly accurate, displays exact RPM with no guessing errors.
With fraction of minute sampling time (1sec).
Maximum, Minimum and Last Measured value.
Designed to fit comfortably in either hand.
Includes 3 contact adapters (2 cones, 1 funnel), surface speed wheel, reflective tape and hard carrying case.
