★【10m-300m Deep Well Water Level Meter】This water level gauge offers precise measurement with a resolution of 1mm and a repeatability error of less than 2mm. Measuring ranges from 10 meters (32.8 feet) to 300 meters (328 feet) are available, making it an ideal choice for water level measurement ★【25mm Stainless Steel Probe】This steel ruler water level gauge is equipped with a robust stainless steel probe. It is activated upon contact with water via waterproof contacts, triggering the peak display and indicator light. It offers fast detection speed, long-term use, and consistent sensitivity ★【Portability】The groundwater level gauge is powered by a 9V battery, making it convenient for construction and carrying, eliminating the hassle of connecting a power cord (batteries not included in the package). It is suitable for various location needs ★【Working Principle】The instrument consists of a sensor probe, a main unit, and a winding reel. When in use, slowly lower the probe head downwards. Once the sensor head contacts the water, it generates an induced electromotive force. After processing by the circuit, this force is converted into an audible and visual indicator. The difference in elevation between the water surfaces and the ground is then read from the measuring scale and converted into altitude ★【Wide Applications】Groundwater level measuring instruments are used to measure water levels in wells, boreholes, and pipes. They are widely used in water conservancy projects, hydrology, environmental protection, and industrial and agricultural fields, such as rural irrigation areas, reservoir dams, river embankments, and power stations
