>>Product Features

1. Light and flexible: advanced transmitter and receiver are designed in one unit, small size, light weight, built-in 200V high-voltage power supply allows you to easily cope with most of survey work, usually needn’t additional bulky battery box.
2. Large power supply, wide range, high precision: 6000W (1200V * 5A) power supply capacity, 100Vp-p of the wide voltage input range, high accuracy measurement of small signals, so that equipment can be applied to work well in high resistance areas, access to a deeper and better measurement results.
3. The "infinite" pole on panel: used to wiring the second and third pole. when using conventional three-pole electrical measurement (combined profiles method and combined electrical sounding method), the instrument can automatically measure ρsA, ρsB, and ρs without operator intervention, reduce human error and improve efficiency.
4. Improved anti-interference technology and high accuracy: using multistage wave filtration, signal enhancement technology and integrated electrical interference suppressor function (with super anti-interference of common-mode and different mode).
5. Automated: SP, drift and electrodes polarization compensation, compensation range is ±10V.
6. The over-voltage protection of receiving part up to 1200V which can protect the instrument on any mistake operation.Transmitting unit supports over-voltage protection, over-current protection and AB open-circuit protection as well as DC high voltage reverse connection protection.
7. Bluetooth technology, wireless remote control: Bluetooth technology enables the tablet PC to control the WDA-1/WDA-1B mainframe in 10 meters. It enables all operations as set parameters, start measurement, display result and save data more easily.
8. Tablet PC operate, powerful function:all operations as parameters setting, data display, data storage, curve drawing all be finished on the tablet PC, easy and visiblefor filed data procession.
9. Grounding resistance check: this function enables the operator to know the ground condition of each electrode.
10. Fault diagnoses: the diagnose program quickly detects fault and finds the damaged part.
11. Sealed configuration: featuring waterproof, dust-proof design and long life time.
