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 PVDF flat tape is laser marked every 1/100 ft or each mm; lengths up to 5000 ft (1500 m). New flat tape has increased tensile strength and electrical efficiency by using 6 strands of copper coated stainless steel and 13 strands of stainless steel in each conductor. The P7 Water Level Meter Probe is engineered to allow submersion to 1000 ft. (300 m). Sensor at the tip of the probe provides consistently accurate measurements in wells, boreholes, and cascading water, with almost zero displacement.
Solinst 101 P2 Water Level Meters use non-stretch polyethylene flat tape, with heat embossed markings each 1/100 ft or mm. Designed for measuring accurate water levels in wells and boreholes, the rugged free-standing reel is well balanced and ideal for use in the field. The P2 Water Level Meter is available with tape lengths to 1000 ft (or 300 m).
