Solinst Model 101 P7 Water Level Meter Series (100 to 2000 feet)

by Solnist

The Solinst Model 101 P7 Water Level Meter with Laser Marked Tape is used for accurately measuring the depth of water in wells, boreholes, standpipes, and tanks. The Solinst Model 101 Water Level Meters are the industry standard for portable hand operated meters. They are sturdy, easy to use and read accurately to 1/100 ft. or each millimeter. 

The Solinst Model 101 P7 features a pressure-proof probe rated to 500 psi and permanently laser marked PVDF flat tape that is traceable to NIST and EU measurement standards.

The corrosion-proof stainless steel probe is submersible up to 1000 ft. (300 m), making it ideal for measuring the total well depth. The sensor at the tip of the probe provides consistent measurements with almost zero displacements.
