Model AD03 - Multi-Function Electrical System
Introduction: D03JSR multi-function electrical system is a multi-function data collection and data site processing instrument, it can be the independent instrument which can survey groundwater and metal ore, also can be used as the slave instrument to form the field scene measurement and control LAN with the wild host( transmitter, multi-function electrical instrument etc.). The main measurement parameters including: 1. SP(self-potential), 2. DC resistivity, 3. The primary field and the secondary field of IP rate decay curve in the time domain induced polarization method. When many slaves work with one host, it can do the high density resistivity method and high density time domain IP method, and the field electrode array method including: 1. Intermediate gradient method, 2. Dipole-dipole, 3. Four-pole sounding.
D03JSR multi-function electrical system is mainly used for the groundwater resource exploration, also be used for the induced polarization prospecting of the metal ore(copper, lead zinc), and the instrument can find out the underground resistivity and polarizability profiles, which can be used for engineering geophysical. Therefore, the instrument can be applied to the geological department, the hydrological department, the railway department and urban underground exploration department.
