The IGIS signal stacking based Signal Enhancement Resistivity Meter Model SSR-MP-AT-SAL is
a state of art microprocessor based data acquisition system. The instrument design incorporates
several innovative features and advanced techniques of digital circuitry to make it a reliable
geophysical tool providing high quality data useful for mineral and groundwater exploration and any
other geophysical applications.
The SSR-MP-AT-SAL sends the entire current into the ground without wasting power for constant
current generation thus increasing the signal strength to probe deeper layers.
The advanced design of SSR-MP-AT-SAL Resistivity Meter achieves excellent depth penetration with
relatively low power inputs. It utilizes the signal stacking up to 16 successive readings to achieve good
signal enhancement. In the presence of random (non-coherent) earth noises, the signal to noise ratio of
the SSR-MP-AT-SAL measurement will be enhanced by ? N where N is the number of stacks. Hence
SSR-MP-AT-SAL Resistivity Meter can be used for depths of upto 600m under favorable geological
field.
Powered by internal rechargeable batteries, instrument provides spot
measurements of Short Normal, Long Normal, Point Resistance and SP and finds extensive application
in groundwater exploration, engineering studies and other lithological investigations.
Instructions for field personnel for operation and maintenance of instrument are minimal and the
logging party does not have to depend on specialized technicians for routine operation.
