digital tachometer

digital tachometer is a high quality instrument using non-contact (Laser / Photo) and contact method to measure the Rotational Speed(RPM) and Surface Speed with wide measuring range and high resolution. It is featured with high accuracy measurement, quick measuring time and long detecting distance up to 500 mm (20 inch) with Laser.

You can operate the meter in the following 3 modes:

• Laser Photo (non-contact): measure the Rotational Speed (RPM)
• Rotational Speed (contact): measure the Rotational Speed (RPM)
• Surface Speed (Contact): measure meter per minutes (m / min)

tachometer is very easy to use by applying a reflective mark (included in package) on target object, then aim at the mark by Laser beam. This tachometer has wide range of applications include measuring rotating speed of machine, motors, model cars, wheels, lathe for metal or  wood cutting work
