Instroduction:WDJD-4 Multi-function Digital DC Resistivity/IP Meter is our new generation model with 32 single-chip and 24 bit A/D technology on the basis of years of experience of design and manufacture,Website:, which could carry on Res and IP survey at the same time. 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.The single WDJD-4 can conduct general electrical resistivity/IP survey with twist pair wire, iron electrodes and power source. If WDJD-4 is used together with WDZJ-4 multiplex electrode switcher multi-electrode cable, electrodes and power source, it can conduct not only general electrical resistivity/IP survey but also multi-electrode 2D Resistivity imaging.Underground water inspectionEngineering geology inspecting as dam base exploration and floodMetal and Non-metal source explorationCity geophysical explorationRailway and bridgeTechncial Specification:Receiving partVoltage channel: ± 6 VSurvey precision: if Vp=10 mV then ± 5‰ ± 1 LSB, if Vp < 10 mV, then ±1% ± 1 LSBInput impedance: =50MOApparent polarizability precision: ±1% ± 1 LSBSP compensation range: ±1 VCurrent channel: 5 A, survey precision: if IP= 10mA then ± 5‰ ± 1 LSB, if IP < 10 mA, then ±1% ± 1 LSSuppression: =80dB for 50Hz industrial frequencyTransmitter partVoltage maximum: 900VCurrent maximum: 5A( when voltage = 900V )Pulse width: 1~ 60s, duty ratio 1:1OtherOperating temperature: -10?~50?, humidity: 95 %RHMemory temperature: -20?~50?Instrument power: eight D size batteries (or same specs nickel-cadmium battery)Complete appliance current: = 55mAWeight: = 7 KgDimensions (L×W×H): 310mm X 210mm X 210mmStandard configuration List of WDJD-4 undergound water finderNo.DeatilsQty1WDJD-4 Mianframe1 Set2USB Communication Line1 Set3Charger1 Pc412V Power Input Line1PC5Instrument backpack1PC6Windows Software U Disk1PC7Operational Manual1PC8Unpolarized Electrodes1Pair9Iron Electrodes10PCS
