WQGO Series is a new state-of-art geophysical instrument renowned for simple, economical and field friendly , ‘Centralized System ‘ for “Multi-Electrode Resistivity Imaging Survey”. It has multiple functions such as high accuracy, quick operation, high reliability, and excellent expandability. It makes field surveys more economical and comfortable. It has the coupling unit of Mainframe (ERI) and Multiplex Switcher (WERT 60/120/4B System) designed explicitly for resistivity imaging survey. Multi-Electrode Switcher is available in three configurations as a Centralized system namely WERT-60 (Supports up to 60 electrodes) ,ERT-120 (Supports up to 120 electrodes in continuous Switcher mode) and ERT-4B (Supports up to 120 electrodes in discrete switcher mode) respectively. ERT -60/120/4B arrangements are compatible to work with the ‘Centralized Cable System’ (30 take-out available at 2m, 5m, 10m, and 20m standard spacing) for Resistivity Imaging /Tomography function.
