What is Resistivity?

Electrical resistivity (also known as specific electrical resistance) is a measure indicating how strongly a material opposes the flow of electric current. A low resistivity indicates a material that readily allows the movement of electrons. The SI unit for electrical resistivity is the ohm metre.

How can Resistivity be Measured?

Resistivity can be measured in the laboratory using a bench Resistivity Meter, or in plant and process applications an online Resistivity controller would be used.

What products do R.M.S Ltd offer for Resistivity Measurement?

Laboratory Applications:

Our CyberScan multi-function Analytical Laboratory instruments offer the user the ability to measure a range of different parameters. You can choose from our competitively priced CyberScan PC510 giving you the option to measure pH, Conductivity, TDS & Temperature through to our top of the range CyberScan PCD5000 offering pH, mV, Ion, DO, BOD (Biological Oxygen Demand), Conductivity, Salinity, TDS, Resistivity & Temperature all from the same instrument!
