-As the name suggests, a water-finding instrument is an instrument for finding water. The water-finding instrument is generally divided into a natural electric field detection meter and a traditional artificial electric survey instrument.Agriculture Meter.
Their principles are basically the same. They are based on the electromagnetic (conductivity) difference between the melt and the surrounding rock in the earth's crust, through observing the naturally occurring electric field (artificial power supply electric field), to study the geological structure and find useful mineral resources. Agriculture Meter a
type of geophysical exploration method that solves geological problems such as engineering, environment, disasters, and water.
The natural electric field frequency selector is small in size, light in weight, and easy to carry; there is no artificial electric field source and two people can work; the exploration depth is large and the work efficiency is high; after the frequency selection device is adopted, the anti-interference ability is strong; 10 working frequencies The data obtained is equivalent to the measurement results of 10 symmetrical quadrupole apparent resistivity profiles with different electrode distances; it overcomes the shortcomings of the DC method of long-distance drawing and heavy equipment; it can work in a small range, especially suitable for rapid mountainous areas. Census and urban geophysical work.
In recent years, the instrument has been sold all over the country, and has been widely praised by experts in hydrogeology, engineering geology and geophysical prospecting, and has received unanimous praise from users.Agriculture Meter
Natural electric field frequency selection method, referred to as frequency selection method. It is based on the electrical difference of underground rock and ore, through frequency-selected measurement of the natural magnetotelluric field (frequency of 0.n-30 kHz), the change law of several different frequencies of electromagnetic field, to study the underground geoelectric field Changes in the situation, to achieve an alternating current exploration method to solve geological problems. The instrument used in this method is called a natural electric field frequency selective object detection meter.
