DSHT-2S Multi-Function Natural Electrical Field Detector is a water detector which is specifically designed for depths of 200-300m. It monitors the changes of underground electrical resistivity by measuring the intensity of electrical field, then analysing the position and depths of underground water. This instrument solved a major issue how to mask the noise signal and amplify the selected signal in a natural electrical field. It consists of anti-water shell and touch screen, which is easy of handling and easy to learn. This instrument was patented, patent number: 201310205318.9、201110454869.X、201320054153.5、201120214308.8、201120567915.2、201320303919.9 DSHT-2S Multi-Function Natural Electrical Field detector is portable, efficiency, easy-handling and accurate analysis. It is auto-measuring which could show data and curves clear and simple. Comparing with traditional DC electrical water detector, its speed of measuring was increased more than 8 times, but the instrument weight was decreased 8 times. In the past 20 years experience, we won a high reputation and were high acclaimed by our customers. Main applications: Mainly using for finding information of underground water, such as the position, depth, flowing direction, water yield etc. It could solve major issues like drinking water, industrial water and agriculture water. In the past 20 years experience, we won a high reputation and were high acclaimed by our customers.
