WGMD-30 Micro Electrode Distance 2D ERI System

WGMD-30 Micropolar distance 2D ERI system designed the control mainframe, the power supply and the electrode switcher in one unit. It features fast measurement with high accuracy, easy operation with tablet PC and light weight. The system is mainly for the rock specimen research, the rock outcrop exploration, the laboratory flume experiment, the non- destructive exploration on cultural Relics Protection research as well as the dam leakage and so on.


•   Portability and flexibility: 
the transmitter, the receiver, the power supply and the electrode switcher are all designed in one unit, small and lightweight. The100V internal transmitting power can conduct the measurements without external power. 

•   Wide measuring range, high precision and high input impedance: 
the  voltage input range is 160Vp-p, the measurement accuracy of the voltage and current small signal is extremely high , and the input impedance is up to100M, which all enable the system to apply for the rock sample research with a high resistance.

•   Table PC operate, powerful function:
all operations as parameters setting, data display, data storage, curve drawing all be finished on the tablet PC, easy and visible for filed data procession with a high working efficiency.

•   Excellent anti-interface performance:
integrated with multistage filtration and signal enhancement technologies and suppression against common mode interference and differential mode interference. Measurement precision is high.
