Specification: Item Type: Digital LED Tachometer Product Material: ABS Basic Parameters: Input Signal: Proximity/Photoelectric/Electronic Switch NPN Normally Open (Non Linear Change Signal) How to Use: Take out the product, install and use. packing list: 1 x Speed Meter 1 x Sensor 1 x Weak Magnetic Component 1 x Bracket Notice: 1. Try to reduce the use of strong electromagnetic devices to avoid interference;2. Ensure that the Hall switch and magnet are securely fixed during the testing process to prevent vibration from causing fluctuations

• Clear LED Display & Alerts: Features a bright 4-digit red LED for easy reading. Visual and audible alerts for under-range () or over-range () speeds enhance monitoring.
• Versatile Speed Modes: Supports 5 speed units including ultra-low speed function down to 3 RPM. Ideal for both high-speed motors and precise slow-moving equipment.
• Robust Hall Sensor System: Includes NPN hall proximity switch and weak magnetic component. Minimizes interference for reliable performance in industrial environments.
• Flexible Parameter Settings: Easily configure 9 settings (H1-H9) like upper/lower limits and speed ratio via SET +/- keys. Suitable for complex applications like conveyor belts.
• Accurate RPM Measurement: Wide measuring range RPM with ±(2%+1) accuracy. 2 times per second refresh rate for real-time speed detection on various machinery.
