DSHD-6A Multi-Function DC Resistivity & IP Instruments

Main Applications:

By using corresponding parameters of apparent resistivity and induced polarization method, the measuring apparatus is widely applied to many aspects including energy exploration, railway and bridge engineering exploration ,metal and non-metal mineral resources exploration, city geophysical exploration, etc.

Accessories and relevant fittings made by our factory with 60-channel or 120-channel multiplex electrode switch, also can be used for multi-electrode resistivity survey system and so on.

Determine the hidden safety risk location in reservoir dam foundation and flood-control dyke. Search for groundwater, solve the drinking water problems of human and animal as well as industrial and agricultural water issue. search for geothermal and other hydrological, engineering geological exploration. find faultage zone and collapse column, landslides, coal mining goaf.

Main Advantages：

Various Measurement Parameters: Instrument can be applied in direct measurement and indication of primary potential Vp, spontaneous potential Vsp, power supply current I, , apparent polarizability Ms ,apparent resistivity Ro, half-decay time Th, degree of decay D, integrated IP parameters Zp, and degree of deviation R.

Multiple functions in One Machine: The instrument has three functions including long lead IP instrument, and medium-power short lead transmitting. master of 2D resistivity imaging system,

More flexible and convenient operating mode: Adopt all-digital automatic measurement, can execute automatic compensation for spontaneous potential, drift and electrode polarization. Use large screen LCD display, can directly display the arrangement of nine electrodes; directly input into pole arranging parameters with keyboard; measuring resistivity curve apparent polarizability curve, half-decay curve, etc. can be displayed directly when measurement of measuring point completes,

Data Interpretation is more convenient: The instrument can measure points on 4,800 survey data for storage. Each measuring point has 22 data, with RS-232 serial interface, through appropriate software the stored data can be directly transfer to the computer for digital interpretation of various methods.

Small-sized, Light in weight: The instrument integrates receiver and transmitter together in the same cabinet, which can be used for measurement via apparent resistivity method and induced polarization method.

Beautiful Instrument Apparent, Strong Structured: The aluminum chassis effectively enhance the electromagnetic shielding; adopts thin-film multi-layer sealed touch panel; multiple over-voltage, over-current automatic protection are set for internal power supply part, allowing the instrument to be suitable for various
