HIGH PRECISION MEASUREMENT: Measuring range: 10-9999; Measurement accuracy: ±0.1%, reading ±1 word; Display refresh rate: >3 times/second

ANTI-INTERFERENCE: Comes with Hall sensor and magnet, good stability, accurate Hall induction, reliable speed measurement, strong anti-interference ability.

LED DISPLAY: Equipped with 4-bits digital LED display, which makes the speed meter clear and easy for reading.

OVER-RANGE DISPLAY: If the rotation speed is too low, it will display "LLLL"; if the rotation speed is too high, it will display "HHHH"
