Product Description

Product Description

WTEM Transient Electromagnetic Underground Water & Metal Detection Equipment

TEM, also know as  time-domain electromagnetics (TDEM), is a basic electromagnetic method to detect viriarions of subsurface electrical resistivity. TEM works better in deeper location than DC resistivity, particularly for mapping conductive aquitards (confining layers) in resistive sections. Whereas the DC technique has difficulty mapping strata below a resistive layer, TEM can easily map conductive strata beneath a thick resistive section. Besides, it allows meaurements to be made rapidly, and survey costs are generally less than those associated with conventional DC resistivity surveys or, conversely, larger areas can be surveyed in greater detaul for comparable cost. On the contrary, it also have very obvious disadvantage. It can be only applied in relatively flat ground. The measurement maybe not accurate if the terrain is complex and variable.

Features & Function

Features:
* High accuracy and low power consumption: reasonable heat dissipation measures, solid mechanical structure
* Wireless remote control: remote control the receiver via tablet PC within 10 meters from the receiver, easy to set parameters, start measurement, transmission and display of measurement results
* High anti-interference capability: programmed hardware filters, unique and accurate power supply frequency, data overlay, and software filtering gives the instrument exceptional anti-interference capability
* Multi-channel, high measurement accuracy: Number of channels can be set; logarithmic or linear distribution optional; the use of high-precision crystals to complete the timing, the time-depth relationship is stable and accurate, the measurement of sub-sample window distribution is reasonable, and the true reflection of the underground information
* Transmitters with rapid shutdown: with fast shutdown function to extend the shallow detection range as much as possible; the shutdown time measurement function can provide the interpretation software with an accurate actual shutdown time of the transmitter to improve the accuracy of software interpretation
* Multiple working modes: Accept point measurement mode and  fast walking continuous measurement mode
* Ultra-shallow depth detection: easily detects ultra-shallow depths from a few meters to hundreds of meters

Functions:
* Quick survey, stereo mapping
* Deep mine finding and shallow detection
* Metal mine, coal mine detection
* Oil, gas, geothermic field detection
* Hydrological & engineering geology survey
