Product Description

 

Product Description

Feature:

1. CONTACT DRIVE SHAFT: Adopting microcomputer (MCU) technology for accurate low resistance bearing drive, contact measurement of rotational speed, line speed and line length
2. LESS INFLUENCE TRANSMISSION: The use of low resistance bearing transmission has less influence on the speed of the motor under test
3. WIDE APPLICATION: Widely used in home appliance industries such as fans, washing machines, machinery production such as bearings and gears, vehicle speed line speed measurement, electrode motor equipment measurement
4. CLEAR AND ACCURATE: 5 digit LCD screen display, 18mm character height, clear to read. Time base adopts 6MHz quartz crystal vibration, accurate and stable
5. 0.5~19999RPM RANGE: The range of digital tachometer RPM meter is from 0.5~19999RPM, support automatic range switching, flexible and convenient
