Solinst 101 Water Level Meter

Solinst 101 Water Level Meter



The Solinst 101 Water Level Meter uses a choice of probe designs, attached to a permanently marked polyethylene tape, fitted on a well-balanced reel. It is powered by a standard 9volt battery housed in an easy-access battery drawer. The conductors embedded within the tape each have seven strands of stainless steel for strength and flexibility.

The Model 101 Water Level Meter uses a 9V battery and a small diameter probe on narrow coaxial cable. 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 off the cable at the top of the borehole, casing or tube and by accounting for the distance from the point of measurement to the nearest marking on the cable.

Optional Extras

Power Reels

Power reels can be very useful to allow faster or less strenuous operation of longer lengths of tape. The 110 volt power reels are available on request.

Carrying Bag

Padded nylon carrying bags are available, as an optional extra. The sturdy design has a convenient shoulder strap, zippered front pocket, zippered top, and a grommet in the base to prevent moisture build-up.

Replacement Parts

Replacement probes, tapes with probe and other spare parts are available. Meters can also be returned directly to Solinst, or to authorized repair facilities in Canada or the U.S.A. for service or repair.
