328 Ft (100 m) Groundwater Level Meter with Stainless Steel Probe and Steel Tape, Electronic Water Level Measuring Instrument with Buzzer, Indicator Light and Voltmeter 150M

What is the working principle of a water level gauge?This water level gauge uses a stainless steel probe connected to a steel tape measure. When the probe touches the water, the circuit is activated, and the buzzer and indicator light immediately illuminate. The water level can then be read directly from the steel tape measure at the wellhead or well pipe.Specifications:Name: Steel Tape Water Level GaugeMeasuring Range: 100m (328ft), 150m (492ft)Resolution: 1mmRepeatability Error: ≤±2mmMeasurement Signal Display: LED, BuzzerApplicable Temperature: -20℃~+60℃ (-4℉~140℉)Power Supply: 9V dry cell batteryPackage List:1 x Steel Tape Water Level GaugeNotes:1. The instrument should be stored in a dry, well-ventilated room with a temperature of -10~+40°C and an humidity not exceeding 80%, from corrosive gases.2. Due to limited battery capacity, the power switch should be turned off immediately after each measurement.3. Do not bend the measuring cable, especially near the side end, to avoid damage.After-sales service: If you have any questions, please contact us and we will be happy to assist you.

• 【Precise Water Level Detection】This water level gauge is powered by a 9V battery and features a stainless steel probe that connects to a steel measuring tape. When the probe contacts the water surface, the circuit is activated, emitting a clear beep and illuminating an indicator light, enabling fast and reliable water level detection.
• 【High-Precision Measurement】This well water level gauge measures in centimeters with a minimum resolution of 1 millimeter and a repeatability error within ±2 millimeters. Available in 100-meter (328-foot) and 150-meter (492-foot) lengths, it is ideal for measuring water levels in wells, boreholes, reservoirs, and groundwater monitoring applications.
• 【Durable Stainless Steel Probe】This groundwater level gauge features a 25-millimeter (0.99-inch) stainless steel probe with built-in waterproof contacts, offering excellent corrosion resistance and long-term durability. The probe is detachable for easy cleaning and maintenance, ensuring stable use under various water quality conditions.
• 【Roller Design】This borehole water level gauge features an independent roller with a handle, smooth winding, and a reliable brake, ensuring precise and controllable use. The steel ruler features clear graduations for easy depth measurement; the built-in battery compartment makes the device compact and portable, suitable for field use.
• 【Wide Applications】This deep well level gauge is suitable for water wells, boreholes, water tanks, reservoirs, and water pipelines. It is commonly used for groundwater monitoring, hydropower projects, dam inspections, and long-term water level observation. Operating temperature range: -20°C to +60°C (-4℉~140℉).
