Conductivity Measurement
Our broad range of conductivity cells encompasses three measuring techniques: 2-electrode cells for µS/cm ranges, 4 and 6 electrode sensors for mS/cm levels and non-contact, electrode-less sensors. |
2-Electrode Contacting Cells - Range 0 ... 10,000 µS/cm
High accuracy technique for trace conductivities from ultrapure water to industrial rinse waters. An alternating current is passed between two electrodes in contact with a solution. The transmitter converts the resultant potential difference into conductivity, concentration or specific resistance.Table 1 of 3
