The Solinst Model 102 Water Level Meter is purpose-built for accurate groundwater level measurement in narrow-diameter wells, including piezometers, small monitoring wells, and tubing installations where standard water level meters cannot be used. Its slim probe design and flexible coaxial cable allow for smooth deployment in tight or obstructed boreholes while maintaining reliable, repeatable readings.

Designed for demanding field conditions, the Model 102 provides clear audible and visual indicators for precise water detection. Segmented probe weights enhance flexibility, while a recessed probe tip helps reduce false signals caused by cascading water, making it ideal for environmental monitoring, hydrogeological investigations, and regulatory sampling programs.
