Super Digital DC Resistivity Meter High Deep Water Detector Geothermal Exploration

Product Description

The WDA-1 Super Digital DC Resistivity Meter represents the culmination of years of development and production of advanced electrical measurement instruments by our team. This next-generation digital DC meter incorporates cutting-edge technologies, including a Windows 10 tablet interface, Bluetooth connectivity, a 24-bit A/D converter, and high-power control systems. Remarkably, the instrument has been significantly reduced in both size and weight while achieving superior technical specifications and capabilities that outpace those of comparable products currently available in both domestic and international markets. As a result, it is exceptionally well-equipped to perform effectively in varied and complex environmental conditions.
