For measuring the depth of water in wells, boreholes, and standpipes, the Model 101 Water Level Meter is the most accurate and reliable meter. It is sturdy, easy-to-repair and read to 1/100 ft. or to each millimeter.
Also available, from Solinst, is the less expensive Model 102 Coaxial Cable Water Level Meter for use in small diameter tubes.
