¡¡¡¡WDA-1 Super Digital DC Resistivity/IP meter
¡¡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 exploration.
Features:
- Portability and flexibility¡ª¡ªcombining transmitter and receiver
together, small and light.
- Real one machine and multi-function¡ª¡ªvoltage 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..
- Multi-parameter measurement, wide application¡ª¡ªvoltage,
current, apparent resitivity, SP, apparent chargability, metal
factor, half life, attenuation, IP ratio, departure, IP spectrum.
- Blue technique, wireless remote control¡ª¡ªPocket PC controlled
central unit by Bluetooth technique, remote control is effective
within 10 m. All parameters and measurement display can be
fulfilled easily wirelessly.
- Pocket PC control, Powerful function¡ª¡ªall Chinese pocket
PC support the man machine interface and sampling control,
parameters setting, data display and storge, graph plot, image
making, Field works are very easy.
- Extendable easily¡ª¡ªdata sampling and storage are all controlled
by pocket PC. Data management is easy and software is easy
to be extended.
- Powerful pocket PC¡ª¡ªbeside 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.
- With double high-density resistivity cable port, cross-hole
resistivity can be carried out without medium switcher. Measurement
is concise and easy.
- 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 ¡À1% accuracy£©. Tool
is fitted for high resistivity region; high-density can achieve
good results.
- Complete anti-interface technique¡ª¡ªuse multi-stage filter
and signal enhancement technique, integrate anti-interface
funation, accuracy is high.
- Auto SP, shift and electrode compensation with range as
high as ¡À10V.
- The panel has ¡°infinite¡±pole for pole-pole and dipole-pole
measurement. During dipole-pole measurement, ¦ÑsA,¦ÑsB, and
¦Ñs can be measured automatically with high efficiency.
- Receiver has over-voltage over- current and AB open protection
ability.
- Ground resitivity check©¤©¤AB pole and MN pole can be checked
at any time, easy and practically.
- Dignosis program can find the trouble with the tool quickly
and accurately.
- Imported air proof box is water-proof, dust-proof, and long
life.
- Flexiable control choice©¤©¤the tool can be controlled with
note PC for field work.
