The development of geophysical instruments
in company SIHAYA Ltd. has three main streams:
seismograph SEISMUT 6
100 channel direct current resistivimetric instrument GEA 7
direct current resistivimetric instrument GEA 6
Output of instrument GEA 6 measurnig VES-IP:
older instruments line:
seismograph SEISMUT IV
seismograph SEISMUT III
- easy portable with removable notebook (enables all interpretation in terrain)
- 16 bits A/D converters + 4 steps pregain 0 - 60 db, dynamic range 96 db
- automatical setting of gain and geometry of measurement, addition -summation of seismic records ...
- 32 to 1 channel, input single-sideband filter 3-2500 Hz, 50 Hz digital filter
- minimal sampling interval 9 ms for one channel to 300 ms for 32 channels
- optional length of record in save format SG2
- seismograph works reliably even on most difficult circumstances, (see the picture right)
GEA II - instrument for resistivity direct current measurements
- is easy portable direct-current resistivity meter with removable notebook (enables full interpretation of VES and resistivity profiling measurements immediately in terrain)
- 21 bits A/D converters, commutation of current
- precision of measurement is 5 uV and 5 uA
- possibility of using preset parameters for measuring VES, resistivity profiling and SP...
- digital record in save format sheet-table *.txt
- presetable automatic modification of the geometry of measurement
