The land 3 component string is one of the newest models developed by our independently to proviced the industry with a practical solution to the field problem of 2-C and 3-C arrays using 2 and 3 component geophones. This model is provided w...[more]
WZG-6A, WZG-12A, WZG-24B is based on WZG-24 engineering seismograph. The instruments need to work with industrial computer or notebook. The external computer could collect data though USB interface; while internal rechargeable battery ensur...[more]
For all our seismograph with different channels, we will supply a data acquisition software, which is only used to do some simple procession, but it abviously is not enough. For 24 channels, 48 channels seismographs, there is a WinSeis Lite...[more]
l When complete with this GPS synchronized controller, receiver should choose GPS synchronization and transmitter chooses External synchronization. l To adjust transmitting frequency, first rotate the power switch (on the GPS synchronized co...[more]
l Effective distance for Bluetooth wireless communication is within 10 meters; if out the range, communication would fail and it needs to pair Bluetooth once again. l Lay the transmitting coil and receiving coil according requirements; rest...[more]

I.P. surveys have traditionally been used in the mineral exploration industry, particularly for metal sulfides, where heavy electrical generators producing high currents of the order of 10 Amperes are used. The apparent I.P. values from suc...[more]
Summary of different array types The Wenner array is an attractive choice for a survey carried out in a noisy area (due to its high signal strength) and also if good vertical resolution is required. The dipole-dipole array might be a more s...[more]
