Solinst Model 102 Water Level Meter With P4 Probe (200 & 300 FT IN STOCK)

Solinst Model 102 Laser Marked Water Level Meter With P4 Probe The Solinst Model 102 Water Level Meter 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. Operating Principles The Model 102 Water Level Meter uses a choice of two small diameter probe designs, attached to a narrow coaxial cable, fitted on a sturdy ergonomically designed reel. A standard  9 volt battery, housed in an easy-access battery drawer, powers the Water Level Meter. When the probe enters water the electrical circuit is completed, sending a signal back to the reel where a light and clearly audible buzzer are activated. The water level is then determined by taking a reading directly from the cable at the top of the well casing or borehole. A sensitivity control allows the buzzer to be scaled back or turned off while in cascading water, and ensures a clear signal in both high and low conductivity
