Multi-purpose switchbox CommDD2 for electrical survey allows to commutate the receiving and transmitting lines without any limitations. There are 2 possible ways to switch electrodes on the lines — manually or automatically (with a predefined protocol of measurements)....

... performing continuous aquatic sounding on DC or recording EM processes with 72-electrode towing array. A unique 3 kW generator allows using current up to 10 A, and when using an external DC source, 50 A current switching is available (optional). The built-in switchbox is designed to select one of three available array types. This approach, together with synchronous data recording on 32 channels, provides the highest possible resolution and depth of study achieveble with electrical tomography method - up to ...
