Syscal Kid Switch 48 - Resistivity Imaging For Environmental Applications

SYSCAL R1 Plus Switch-48, Resistivity Imaging For Environmental Applications

	Compact yet powerful
	600 V - 200 W ^new - 2.5 A
	Automatic ranging
	Automatic switching

SYSCAL R1 PLUS Switch-48 is a new all-in-one multinode resistivity imaging system. It features an internal switching board for 48 electrodes and an internal 200 W power source. The output current is automatically adjusted (automatic ranging) to optimize the input voltage values and ensure the best measurement quality. The system is designed to automatically perform pre-defined sets of resistivity measurements with roll-along capability. Two strings of cable with 24 electrode take-out each are connected on the back of the resistivity meter. Made of heavy duty seismic cable, these strings are available with standard 5 or 10 m electrode spacing. Customized cables may also assembled for special arrays or non-standard applications.

Compact, easy-to-use and field proof, the SYSCAL R1 PLUS Switch-48 measures both resistivity and chargeability (IP). It is ideal for environmental and civil engineering applications such as pollution monitoring and mapping, salinity control, depth-to-rock determination and weathered bedrock mapping. It can also be used for shallow groundwater exploration (depth and thickness of aquifers).

With the SYSCAL R1 Plus Switch-48 resistivity surveys can be performed very efficiently with one operator only.

RESISTIVITY IMAGING

	Aim: imaging the underground geological structures through surface electrical measurements
	Principle: transmitting a current I through two electrodes and measuring a voltage V with two other electrodes
	Apparent resistivity: p = K*V/I, K depending on the electrode separation
	Resistivity pseudo-section: contoured plot of the apparent resistivity data, using the electrode distance as a pseudo-depth parameter
	True resistivity section: contoured plot of the resistivity distribution obtained through the inversion of the measured data (using a non linear parameter fitting scheme)
	Applications: environmental studies, groundwater investigation, civil engineering, archaeology...
