Laser Marked Water Level Meter 

The Solinst (Canada) Model 101 P7 Water Level Meter features a submersible probe and durable PVDF flat tape. The flat tape has accurate laser markings every millimeter or 1/100 ft., certified traceable to national standards. The tape has high tensile strength, abrasion resistance and electrical efficiency. The P7 Probe is engineered for submersion to 300 m (1000 ft.), ideal for depth to water, as well as total well depth measurements. The sensor at the tip of the probe provides consistent measurements in wells, boreholes, tanks, and even cascading water, with almost zero displacement. A single 9V battery powers the meter.

The standard Model 101 P2 Water Level Indicator with heat embossed tape is also available.
