HI-2315 utilises a four ring potentiometric probe with platinum sensor that offers greater versatility and accuracy over amperometric designs.
A potentiometric probe works on the principal of induction which eliminates the effects of polarisation (a common problem of amperometric systems). Two outer rings apply an alternating voltage and induce a current loop in the solution while two inner rings measure the voltage drop induced by the current loop (which is dependent on the conductivity of the solution). By utilising the 4-ring method, it is possible to measure very low to high conductivity levels (up to 200 mS/cm) without changing probes.
