    4 Digital Red LED Tachometer RPM Speed Meter AC 110V-230V Digital Motor Tachometer with Hall Proximity Switch Sensor NPN for Lathe Conveyor Belt

    • HIGH PRECISION MEASUREMENT: Measuring range: 10-9999; Measurement accuracy: ±0.1%, reading ±1 word; Display refresh rate: >3 times/second
    • ANTI-INTERFERENCE: Comes with a Hall sensor and magnet, ensuring excellent stability and accurate Hall induction for reliable speed measurement. Additionally, it boasts strong anti-interference ability, making it a dependable choice for a variety of applications. The Hall sensor and magnet work in tandem to provide precise measurements, while the device's overall design ensures consistent performance over time.
    • LED DISPLAY: The speed meter is equipped with a 4-bit digital LED display, which offers exceptional clarity and ease of reading. This feature allows for precise monitoring of the speed, even in low-light conditions.
    • 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"
    • PLEASE NOTE: 1. Minimize the use of strong electromagnetic devices to avoid interference; 2. Ensure that the Hall switch and magnet are securely fixed during testing to prevent vibration, which can cause jumping or inaccurate readings. Additionally, maintain a distance of no more than 10mm between the Hall switch and magnet.
