Single-Use Technology
The conductivity sensor ACF60 features a superior six-electrode, four-pole design. The arrangement of the four electrodes applying current around the two electrodes measuring the resulting voltage guarantees reliable and precise measurements in a broad conductivity range. In combination with the optek C8000 universal converter the ACF60 sensor allows a wide dynamic range 0 – 850 mS/cm. This unique design provides a greatly reduced sensitivity to sensor fouling and polarization, which extends the sensor’s lifetime.
