Reliable conductivity measurement, with self-checking sensors

While the theory of monitoring conductivity is simple, in practice it can be very frustrating. While simple 2-electrode sensors are inexpensive and can provide accurate data, continuous water quality monitoring of even relatively clean water can foul the electrodes and degrade the measurement. Maintaining accuracy is made more difficult when the amount of solids dissolved in the process varies over a wide concentration range.

ATi’s Q46/45C4 4-Electrode Conductivity water quality monitors are the answer for monitoring almost any water-based process. Drinking water, plating bath solutions, cooling water, process wash water and most other aqueous systems can be monitored accurately and reliably. The unique drive/control scheme used in the 4-electrode system allows a single sensor to be used in conductivity ranged from 0-200 μS to as high as 0-2,000 mS (0-2S). For chemical mixing applications, a concentration display can be selected.
