Details：
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                     Item:DT2236B 5 digits 18mm (0.6") LCD                     Accuracy: ±(0.05%+1 digit)                     Sampling Time: 0.5sec(over 120RPM)                     Range Select: Auto-Ranging                     Test Base: 6MHz Quartz crystal                     Battery: 3x1.5V AAA battery                     Detecting Distance: 50~500mm                     Power Consumption: Approx 45mA                     Measuring Range:                     Photo Tach: 2.5~99,999RPM                                         Surface Speed: 0.05~1,999.9(m/min) Contact Tach: 0.5~19,999RPM     Resolution:                      Photo Tach: 0.01RPM(2.5~999.99RPM)                      　　　　　　0.1RPM(1,000~9,999.9RPM)                      　　　　　　1RPM(over 10,000RPM)                      Contact Tach: 0.01RPM(0.5~999.99RPM)                      　　　　　　　0.1RPM(1,000~9,999.9RPM)                       Surface Speed: 0.01m/min(0.05~99.99m/min)             　　　　　　　0.1m/min(over 100m/min)                      1RPM(over 10,000RPM)
