A versatile dual-functional solution for accurate groundwater measurements

Solinst’s 101D Water Level DrawDown Meter is a state-of-the-art device that combines two essential tools into one, providing accurate depth-to-water measurements in wells, boreholes, standpipes, and tanks, as well as monitoring falling hydraulic head during low-flow sampling, pumping, and other aquifer/well tests.

The 101D Water Level DrawDown Meter features a sturdy reel and frame, a convenient tape guide, on/off sensitivity dial, battery test button, and an easy-to-access 9V battery tray, making it a reliable and user-friendly solution for professionals in the environmental, geotechnical, and hydrogeological industries. The levels are read from a durable flat tape, accurately laser marked every mm or 1/100 ft, with tapes available up to 1500 m (5000 ft). The probe is submersible for the full length of the tape, allowing for easy and efficient measurement in a variety of environments.
