Ken-Tech has been designing and manufacturing water level indicators in America`s Heartland since 1983. We are a small, Wisconsin based company that takes great pride in the quality and performance of our American made products. Water level indicators are portable instruments designed to accurately measure the standing level of water in test wells, boreholes, and similar underground cavities. In use, a sensing probe attached to a measured cable is lowered into the well. A light, buzzer, or panel meter mounted on the instrument will indicate when water has been encountered. Measurements for depth are determined from the markings on the cable.
