2D Resistivity Imaging system geoelectric instrument Res & IP Meter undergrounder water detector mineral finder
Product Describe
The WDJD-3A Multi-Function Digital DC Resistivity/IP Meter is an ideal instrument for individuals who require precise measurements with rapidity, dependability, and outstanding scalability. With years of design and manufacturing expertise, we have produced a product that satisfies the most recent user demands. Other multi-electrode resistivity software can process the WDJD-3A measured data, allowing for more convenient result interpretation.
Main Features and Functions
- Transmitting unit and receiving unit are of all-in-one design, portable and light weight.
- CMOS large-scale integrated circuit, special stand-by mode, compact size, low power consumption.
- System turns off WDJD-3A mainframe automatically if there is no operation in 10 minutes.
- High anti-interference performance and precision, integrated with multistage wave filtration and signal enhancement technologies.
- In good condition, multi-electrode imaging function can complete measurement of a 552-data-points cross section.
- Automatically achieving compensation of self-potential, drift and electrode polarization.
- Receiving unit supports transient over-voltage protection, transmitting unit supports
- Over-voltage protection, over-current protection and AB open-circuit protection.
- Measured curve can be plotted through WDJD-3A mainframe.
- Simple calculator fulfills calculation of geometric factor and other calculations on the spot.
