Main Features
Multiple functions in One Machine: The instrument has three functions including long lead IP instrument, master of 2D resistivity imaging system, and medium-power short lead transmitting.
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.
Various Measurement Parameters: Instrument can be applied in direct measurement and indication of primary potential Vp, spontaneous potential Vsp, power supply current I, apparent resistivity Ro, apparent polarizability Ms, half-decay time Th, degree of decay D, integrated IP parameters Zp, and degree of deviation R.
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.
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 types of field environment
