PQWT-TC use the natural electric field as electromagnetic field work source, based on the resistivity differences of underground rock, mineral or groundwater, measure the natural electric field in the soil of N different components of electric frequency field . After data collection by the unique built-in computing functions, the instrument can automatically draw curve chart and profile map with just one button, according to the profile map, we can clearly understand the geological structure and quickly determine the Location of ore (Sewing), hollow (cave), water (aquifer), etc. The inquiry of you PQWT-TC500 is for 500 meters underground water detctor, it is More accurate, More lightly, and More effective than any other underground water detector. The device is able to AUTO form profile map and curve graph in the instrument, that means you can get the drill position as soon as finished measurement. It will save you a lot of cost and time, and the accuracy can reach 95%,which is proved by our customers. Our instrument is installed 4 language modes ,English/Spanish/French/Arabic. PQWT-China provide Warranty for 2 years . Operation video is as below. It is easy to learn in 10 minutes. http://www.pqwtcs.com/NewsDetail.aspx?nid=3643&classid=273
