Product Description

Geotechnical Portable Electrical Resistivity Meter IP SP Equipment ,VES Water Finder and Deep Mineral Detector

WDJD-4 Multi-function Digital DC Resistivity/IP Meter (hereafter also referred to as WDJD-4 or WDJD-4 mainframe) is the updated model of WDJD-3 multi-function digital DC Res/IP meter, which install a 12V rechargeable battery. 
It features multiple functions, high accuracy, fast speed, high reliability and excellent expandability. Measured data of WDJD-4 can be processed by other multi-electrode resistivity software, which makes the interpretation more convenient.
