Multi Function Underground Water Detector DC IP Resistivity Meter Vertical Electrical Sounding Resistivity Meter Geophysical Water Detection Meter
It is injecting a current (I) into the ground. The receiver voltage (V) measurements are taken in line at an 'a' spacing at 'n a' distances from the current source. The resistance (R) at this point can be calculated using the measured current (I) & voltage (V) with ohm's law (V = I·R). The array geometry is used to calculate an apparent resistivity at depth. The apparent resistivity is plotted as pseudo-section, with each successive n layer plotted deeper.
Main Applications
By utilizing relevant parameters of apparent resistivity and induced polarization method, the instrument is widely used in many aspects including metal and non-metal mineral resources exploration, energy exploration, city geophysical exploration, railway and bridge engineering exploration, etc.
Search for groundwater, solve the human and animal drinking water issue as well as industrial and agricultural water issue.

Main Features
One machine with multiple functions: The instrument has three functions: long-wire IP instrument, two-dimensional high-density electrical measurement system host and medium-power short-wire emission.
Small size and light weight: The instrument integrates the transmitter and the receiver into the same box, and can measure the apparent resistivity method and the induced polarization method at the same time.
Many measurement parameters: the instrument can directly measure and display primary potential Vp, natural potential Vsp, power supply current I, apparent resistivity Ro, apparent polarizability Ms, half-life Th, attenuation D, comprehensive IP parameters Zp and deviation Degree R.
The operation mode is more flexible and convenient: it adopts fully digital automatic measurement, which can automatically compensate for natural potential, drift and electrode polarization. The large-screen LCD display with Chinese characters can directly display nine electrode arrangements; the keyboard can directly input the distribution parameters; when a certain measuring point is measured, it can directly display the resistivity curve, apparent polarizability curve, half-life curve, etc.
Data interpretation is more convenient: the instrument can store the measurement data of 4800 measuring points. Each measuring point has 22 data and is equipped with an RS-232 serial interface. The stored data can be directly transferred to the computer through the corresponding software for digital interpretation of various methods.
The instrument is beautiful and sturdy: the all-aluminum chassis is used to effectively improve the electromagnetic shielding; the film is fully sealed to touch the multi-layer panel; the internal power supply part is provided with multiple overvoltage and overcurrent automatic protection, so that the instrument is suitable for use in various outdoor environments.
Data Interpretation is more convenient: The instrument can measure points on 4,800 survey data for storage. Each measuring point has 22 data, with RS-232 serial interface, through appropriate software the stored data can be directly transfer to the computer for digital interpretation of various methods.
Beautiful Instrument Apparent, Strong Structured: The aluminum chassis effectively enhance the electromagnetic shielding; adopts thin-film multi-layer sealed touch panel; multiple over-voltage, over-current automatic protection are set for internal power supply part, allowing the instrument to be suitable for various types of field environment
Using the relevant parameters of the apparent resistivity method and the induced polarization method, artificial direct current is used to supply power to the earth. After the instrument receives the data and processes and analyzes it, it can understand the changes of different parameters to analyze and judge the geological anomalies. It belongs to the instrument type instrument with a long-standing theoretical and practical foundation in electrical geophysical exploration, and is the most basic instrument used in "geophysical exploration" instruments. So far, it has brought huge economic benefits to many mining enterprises and geological units. It is recognized as one of the electric methods with low cost, high accuracy and convenient operation.
