Solinst Model 101 P7 Water Level Meter Series (100 to 1000 feet)

Solinst Model 101 P7 Water Level Meter Series (100 to 1000 feet)

Availability: In stock

Solinst Model 101 P7 Water Level Meter with Laser Marked Tape for accurately measuring the depth of water in wells, boreholes, standpipes, and tanks. 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. 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.

The Solinst 101 Water Level Meter with P7 Probe features an extremely durable, laser marked PVDF flat tape, with an enhanced dog bone design that is thicker, reducing adherence to the side of well casing.

The tape seal plug design allows the probe to be quickly and easily replaced. Each tape conductor on the 3/8” wide PVDF flat tape contains 13 strands of stainless steel and 6 strands of copper-coated steel, making the tape non-stretch and high in tensile strength and electrical efficiency. The thick dog bone design of the tape prevents adherence to wet surfaces allowing it to hang straight in the application. The stand-alone reel features a convenient carry handle, sturdy probe holder, on/off sensitivity switch, light, buzzer, battery test button, brake, and a tape guide stored on the frame. Choices of probe designs are available on these water level meters. On the P7 version, each probe is attached permanently to laser marked PVDF flat tape which is fitted on a well-balanced reel. This water level meter has a PVDF flat tape and has increased tensile strength and improved electrical efficiency. The P7 pressure probe is submersible to 300 m (1000 ft) and has the sensor mounted at the tip to provide consistent accuracy. It benefits from a long battery life, giving 120 hours or more of normal use with only one standard 9V battery.
