Overview

The Solinst Model 101M Mini Water Level Meter measures the depth to water in wells, boreholes, standpipes and tanks with a compact, light reel. It combines a slim P10 weighted probe, 10 mm in diameter, with a narrow 5 mm (1/5") laser-marked polyethylene flat tape. When the probe tip enters water, a buzzer and a light activate, and the depth is read directly from the tape to 1/100 ft or each millimetre.
