ERT Electric Resistivity Imaging for Ground Water Detection,
Underground Water Finder
Ert Electric Resistivity Imaging for Ground Water Detection,
Underground Water Finder
The instrument is our newly developed product with years of
research and production experience of
advanced electrical tool, which includes many advanced elentronic
technique such as all-chinese pocket
PC, blue tooth, 24 bit A/D, and large power control. This tool has
small size and light weight, and its main
technique specifications and functions are more advanced than
similar tools abroad and home can be
applied in different complex regions. It has been applied widely in
metal and non-metal mineral
propecting, civil propecting, railway, bridge, etc. It can also be
applied in underground water, water
reservoir dam foundation, jetty hidden trouble, and geothermal
1. Portability and flexibility: combining transmitter and receiver
together, small and light.
2. Real one machine and multi-function: voltage and current range
and small signal accuracy improved
greatly, it is fitted for rock sampling tester, large-power IP
receiver, nomal resistivity tool, IP, water finder,
2D and 3D high-density electrical tool etc.
3. Multi-parameter measurement, wide application: voltage, current,
apparent resitivity, SP, apparent
chargability, metal factor, half life, attenuation, IP ratio,
departure, IP spectrum.
4. Blue technique, wireless remote control: Pocket PC controlled
central unit by Bluetooth technique,
remote control is effective within 10 m. All parameters and
measurement display can be fulfilled easily
5. Pocket PC control, Powerful function: all Chinese pocket PC
support the man machine interface and
sampling control, parameters setting, data display and storge,
graph plot, image making, Field works are
6. Extendable easily: data sampling and storage are all controlled
by pocket PC. Data management is easy
and software is easy to be extended.
7. Powerful pocket PC: beside the high hardware configuration,
pocket PC is installed with many utility
software. User can arrange the date, navigate the web via wireless
net, and use WORD, EXCEL,
PowerPoint, and Media Player for office and amusement.
8. With double high-density resistivity cable port, cross-hole
resistivity can be carried out without
medium switcher. Measurement is concise and easy.
9. Super wide range, high accuracy: voltage is as high as 64Vp-p,
small signal measurement accuracy is
high(voltage is less than 0.1mV and current is less 0.1mA with ±1%
accuracy). Tool is fitted for high
resistivity region; high-density can achieve good results.
10. Complete anti-interface technique: use multi-stage filter and
signal enhancement technique,
integrate anti-interface funation, accuracy is high.
11. Auto SP, shift and electrode compensation with range as high as
12. The panel has "infinite"pole for pole-pole and dipole-pole
measurement. During dipole-pole
measurement, ρsA,ρsB, and ρs can be measured automatically with
13. Receiver has over-voltage over- current and AB open protection
14. Ground resitivity check: AB pole and MN pole can be checked at
any time, easy and practically.
15. Dignosis program can find the trouble with the tool quickly and
16. Imported air proof box is water-proof, dust-proof, and long
17. Flexiable control choice: the tool can be controlled with note
PC for field work.
