Product Description
WTEM-3Q is a compact and integrated Transient Electromagnetic Equipment developed by Ranchen Group for shallow subsurface investigations. The system combines the WTEM-2J transient electromagnetic receiver with the WTEM-1X low-power transmitter into a single integrated unit, forming a practical solution for field-based transient electromagnetic surveys.
Designed for efficient field deployment, this Transient Electromagnetic Equipment integrates transmitting, receiving, and control functions in one system, simplifying equipment setup and reducing cable connections during surveys. The design draws on practical experience from both domestic and international shallow TEM systems while focusing on stability and operational efficiency in field conditions.
The WTEM-3Q features relatively high transmitting power, ultra-fast current turn-off, and strong operational reliability. It also offers strong resistance to environmental noise, including atmospheric interference and 50/60 Hz power-frequency noise, helping maintain stable data acquisition during surveys.
With its lightweight structure and low power consumption, the system is suitable for a variety of field environments. This Transient Electromagnetic Equipment can be used in groundwater exploration, shallow geological investigation, engineering surveys, and other subsurface detection tasks where portable and efficient TEM measurements are required.
