Portable Water Level Meter, Steel Ruler Electric Water Level Gauge, with Fixed Probe & Durable Steel Tape, for Wells, Boreholes, Reservoirs & Pipes 50m

Water Level Meter, Water Well Measurement, Water Level Gauge with Fixed Probe and Steel Tape✍Trust in the precision steel tape to deliver accurate depth measurements, allowing you to make informed decisions for your projects.➥ Features:● Instant Water Contact Signaling: A loud audible signal and a bright LED light illuminate as soon as the probe makes contact with water.● Optimal Accuracy: Reliable water level measurement thanks to a minimum scale of 1 mm and repeatability of ±2 mm, the best on the market.● Designed with a stainless steel probe and a durable PVC reel, this groundwater level gauge withstands extreme conditions, from -20°C to +60°C.➥ Operation:1.Lower the probe: Carefully unwind the weighted stainless steel probe into your well, borehole, or riser using the robust reel.2.Listen and observe the signal: As soon as the probe makes contact with the water surface, the circuit closes, activating the loud audible signal and the LED light – your water level indicator.3.Read the depth: Stop the descent immediately. Read the exact water level measurement directly on the graduated scale located at the top of the well or casing.➥ Specifications:Operating Temperature: -20°C to +60°C (-4°F to +140°F)Scale: Minimum 1 mmProbe Material: Stainless SteelReel/Housing Material: Durable PVCPower Supply: Requires 1 x 9V battery (not included)Range: 10 m (3.28 ft), 20 m (65.6 ft), 30 m (98.4 ft), 50 m (164 ft), 100 m (328 ft), 150 m (492 ft), 200 m (656 ft), 300 m (984 ft)➥ Package Contents:1 x Water Level Indicator

• ➥【Versatile Lengths】This water level detector is available in lengths from 10 m to 300 m (33 ft to 984 ft), offering great versatility for groundwater monitoring, dam safety inspections, and water supply management. Its adaptability makes it suitable for various environments, from wells to construction sites, ensuring reliable performance for both professionals and DIY enthusiasts.
• ➥【Operating Principles】9 volt battery(not included), housed inside the reel hub, powers the Water Level Meter. When the probe enters water the electrical circuit is completed, sending a signal back to the reel where a light and clearly audible buzzer are activated. The water level is then determined by taking a reading directly from the tape at the top of the well casing or borehole
• ➥【Measurement Specifications and Accuracy】The measurement unit is centimeters, the minimum reading can reach 1 mm, and the repeatability error is ≤ 2 mm, ideal for measuring well levels. The probe uses a larger 0.99-inch (25 mm) diameter probe for easy removal and cleaning
• ➥【Compact and Sturdy】It features stainless steel probe and resist corrosion, non-stretch tape. Ideal for measuring well level, tank water level and so on. The sensor at the tip of the probe provides consistent measurements with almost zero displacements. The tape seal plug design allows the probe to be quickly and easily replaced if required
• ➥【Multiple Applications】Perfect for measuring water levels in wells, boreholes, and water pipes. This groundwater measuring instrument is ideal for hydropower projects and essential for inspectors evaluating dam body infiltration lines.
