Application scope:

1-Improved WTEM/GPS transmitter synchronization controller: integrates a better and more sensitive GPS module and antenna, with faster synchronization speed, smaller size and lighter weight.
High reliability and low power consumption: the receiver and circuit are well designed, the mechanical structure is sealed and solid, with high reliability, low power consumption and easy operation.

2-High reliability and low power consumption: the receiver and circuit are well designed, the mechanical structure is sealed and solid, with high reliability, low power consumption and easy operation.

3-Remote control: the first receiver in China to use handheld computers and Bluetooth wireless communication technology, which can remotely control the WTEM receiver 10 meters, set parameters, start measurements, transmit and display measurement results.

4-Multi-channel, high measurement accuracy: linear or logarithmic; crystal oscillator completes timing, and the time-to-depth ratio is stable and accurate. The sampling windows are reasonably arranged, which can truly image the underground structure and provide reference for complex geological problems.

5-Short shutdown time: the transmitter supports fast shutdown function, which can expand the shallow exploration range. The short shutdown function provides the software with an accurate shutdown time, enabling it to provide accurate data.

6-Friendly and powerful control interface: Control and collect data from the human-machine interface, such as parameter input, data display or storage, graphic drawing, etc., which simplifies field work.

TEM methods can be used to recover earth resistivity in the following applications: Geologic mapping conductive layers or a conductive interface Groundwater prospecting Mineral exploration surveys Salt-water intrusion Mapping of electrically conductive contamination
