This high-precision water level gauge features comprehensive technical parameters and flexible design to meet various water level monitoring needs. It adapts to water quality ranging from 10μω to 1000μω, handling scenarios from clean water to slightly polluted water. With four depth measurement options (0-30m, 0-50m, 0-100m, 0-150m), ≤±0.5mm reading accuracy, and ≤1ms output response speed, it provides accurate, real-time feedback for underground wells, reservoirs, and industrial water storage tanks.

• New integrated circuit board design for enhanced performance
• Anti-polarization excitation circuit and corrosion-resistant electrodes prevent oxidation and maintain long-term sensitivity
• Quick response circuit design with high speed and sensitivity
• Low power consumption: battery lasts up to two years
• Integrated cable with scale measuring tape for direct water level measurement

1. Real-time measurement: Loosen stop screw of the reel to allow free rotation
2. Turn on power button (power indicator light will illuminate)
3. Insert water level probe into tube while holding steel ruler cable to lower probe slowly
4. When probe contacts water surface, receiving system will emit continuous beep
5. Ruler cable depth reading indicates water level depth

Note for noisy environments: Use peak indicating method by turning switch to voltage level and following same procedure. When probe contacts water surface, voltmeter will indicate immediately.
