Solinst Model 102 and 102M (Mini) Water Level Meter

The Solinst Model 102 WLM is designed to measure groundwater levels, especially in small diameter tubes and piezometers, or where a flexible assembly is needed to get past down hole instrumentation. It utilises co-axial cable marked every mm. Lengths available from 30m-300m. It offers a choice of 2 probes – the P10 probe with OD of 10mm and the P4 probe with OD of 4mm for accessing really narrow channels.
