Geophyiscal Digital DC Groundwater Detector Vertical Electrical Resistivity Sounding Method Earth Resistivity Meter Ves Survey Meter
WDDS-2/2B digital resistivity equipment is a new generation of DC resistivity instrument which is based on a series of advanced electrical equipment for resistivity sounding survey, and adopts 32-bit microcontroller technology and 24-bit A / D technology development.
WDDS-2 is the basic resistivity meter only with function of 1D Res Sounding. WDDS-2B designed with a internal high power on the basis of WDDS-2, up to 200V.
Lightweight and flexible-integrating advanced transmitting and receiving functions, small size and light weight, the built-in detachable high-voltage power supply of up to 200V allows you to easily cope with most measurement tasks, usually without the need to carry an extra bulky battery box .
Ultra-large power supply, ultra-wide range, ultra-high precision──up to 3500W (1000V×3.5A) power supply capacity, 48Vp-p ultra-wide voltage input range, and extremely high small signal measurement accuracy, so that the instrument can be better used Work in high-resistance areas to obtain deeper and better measurement results.
