[Ac Resistivity Meters]
 

•
The instrument incorporates all indegenous tropicalised components which ensure accurate results in any sort of weather.
•
The controls and indicators are conveniently placed to achieve ease and speed of operation.
•
The very low frequency square wave alternating current generated by the generater avoids electrode polarisations and reduces capactive effects to a minimum.
•
The use of two separate units reduces flux linkage between the generator and amplifier circuits.
Highly sophisticated circuits and effective filter make the amplifier highly insensitive towards power line interference.
•
The accuracy of measurement is within +-4% from 01 ohm to 10,000 ohms and +-10% below .01 ohm.
