Conductivity Controllers and Conductivity Instruments
Conductivity is the measurement of electrical resistance or conductance of a solution it is the reciprocal or resistance, i.e: 1/R and was originally expressed in MHOS or micromhos (ohms backwards). This was later changed to today's units of measurement Siemens or microsiemens. Our range of Conductivity Instruments are designed with this in mind.
We supply several options of conductivity instruments including hand held stick meters through to our industrial range which includes conductivity transmitters and conductivity controllers for surface or control panel mounting.
