• The transmitter and the receiver are designed in one unit, portable and light. The 200V internal transmitting power of WDA-1B can conduct Res survey in wide variety of explorations. • It is available to measure data of voltage (VP), current (IP), apparent resistivity (ρS), Self-Potential (SP), apparent polarizability (M~M7), metal factor (G1~G7), half decay time (TH), deviation (r), induce polarization ratio (J) and voltage decay curve, etc. • Max power up to 9000W (1500V*6A), voltage input range is 160Vp-p, high measuring precision of small signal. • Bluetooth technology enables the tablet PC to control the WDA-1/WDA-1B mainframe in 10 meters. • Data collecting and data storage are controlled by tablet PC. Software is flexible to be upgraded and extended. • Integrated with multistage filtration and signal enhancement technologies and suppression against common mode interference and differential mode interference. Measurement precision is high. • Transmitting unit supports over-voltage protection, over-current protection and AB open-circuit protection as well as DC high voltage reverse connection protection. |
