2in1 Digital Laser Photo & Contact Tachometer

This 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)

This 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 etc.

Features

• Large 5 digits LCD Display
• Offers 3 measurement options: Photo / Laser, Contact and Surface Speed
• Use Microcomputer (LSI circuit) and junction laser technique to combine Photo (RPM) and Contact Tachometer (RPM, m/min) into 1 meter
