SZE-02 high-precision digital speedometer is a new product developed for the calibration of standard speed generating devices. It has high measurement accuracy and can be used as a dedicated calibration instrument or a general high-precision speed display instrument. Users can set parameters such as sampling time, number of pulses per revolution, and standard speed. All parameter settings and function selections can be controlled by tapping the switch on the front panel. Simple structure, reliable performance, simple and beautiful appearance. In addition, the instrument can process data in accordance with JJG326-83 "Verification Regulations for Standard Rotational Speed Devices" and print out the processing results through a printer. Suitable for purchasing SZJ-3 and 4 users, used for verifying their accuracy.
