Water Tape 2 - 500ft

This economical water level indicator is ideal for measuring the water level of wells, bore holes, and standpipes.  It signals when water is reached with accuracies to 1/100" of a foot or 1mm.  We use a high quality polyethylene tape, indeibly heat stamped with markings in engineering scale.  The tape is reinforced with Kevlar fibers and flexible enough to wind smoothly onto the nylon reel and hangs straight in the well.  No on/off switch is needed since, when contact is made, the water shorts the probe to complete a circuit.   With 500' (150m) cable.
