ZHPPED 10-300m Portable Deep Well Water Level Meter with Stainless Steel Probe, Boreholes Measuring Tools for Water Well Repairers, Indicator Light, Peak Display 50m(164ft)

【Steel Ruler Water Level Gauge】This provides the most accurate method for measuring water levels. It is commonly used to measure water levels in wells, boreholes, tanks, and pipes, and is particularly suitable for groundwater level monitoring in hydropower projects and for checking dam seepage lines. 【10-300 Meter Well Water Depth Indicator】Our deep well water level indicator achieves precise measurements with a minimum reading of 1 mm and a repeatability error of less than 2 mm. 【Battery Powered】This water level gauge is powered by a 9V battery, making it easy to install and carry without an external power cord. The ergonomically designed reel provides good balance and ease of use. 【Working Principle】This portable water level gauge uses a high-precision stainless steel probe for accurate water depth measurement. When the probe enters the water, the circuit closes, sending a signal to the reel, which emits a clear beep. The water level can then be determined directly from the reading on the reel in the well shaft or at the wellhead. This instrument is suitable for a temperature range of -20°C to +60°C. 【Versatile Applications】: Suitable for various types of wells and groundwater monitoring applications. Whether you are monitoring the groundwater level in a residential well or undertaking a large-scale environmental project, our level gauges can meet your needs.
