Patented six-electrode design reduces sensitivity to fouling and polarization
Wide measuring range: 0 - 10 μS/cm up to 0 - 850 mS/cm
Integrated Pt1000 temperature sensor
No O-rings or epoxy - suitable for CIP/SIP
SIX-Electrodes
The ACF60 conductivity sensor features a superior six-electrode, four-pole design. The patented arrangement of the four current electrodes around the two potential electrodes results in a reliable and precise measurement. This unique design also provides greatly reduced sensitivity to sensor fouling and polarization. The combination of optek C8000 universal converter and ACF60 conductivity sensors allow a wide dynamic range from 0 – 10 μS/cm up to 0 – 850 mS/cm with the same sensor.
Temperature Measurement
The integrated Pt1000 platinum RTD in the tip of the ACF60 sensor provides fast-response temperature measurement for compensation, which can be displayed and transmitted from the C8000 converter.
Sanitary Design
Designed for ultra-sterility, the six electrodes are sealed in the FDA (USP class VI) compliant PEEK sensor tip without the use of O-rings or epoxy. Mounted in an optek inline sensor body, the design ensures smooth and unrestricted flow of all process fluids with minimized hold-up and hydrostatic shear. The ACF60 sensor is suitable for CIP/SIP applications.
pH Electrode Adapter PF12

12-degree electrode orientation provides improved performance
pH electrode solution ground allows inline diagnostics
Designed to enhance flow and minimize hold-up volume
Suitable for most Ø 12 x 120 mm pH-electrodes
12 Degree
The optek PF12 pH electrode adapter is designed to mount pH electrodes at the optimal angle of 12 degrees. This allows the sensor to use electrolyte-filled glass electrodes and improves the functionality and life time of the pH probes. The PF12 electrode adapter is compatible with a broad variety of pH electrodes.
Solution Ground
The PF12 is equipped with a solution ground (earth) connection mounted to the sensor body. This allows the use of pH electrodes that incorporate differential pH input techniques. Additionally, the solution earth connection provides a highly stable measurement while enabling sensor diagnostics including low glass impedance, out-of sample, and broken electrode/cable warnings.
Sanitary Design
Mounted in an optek inline sensor body the design of the PF12 ensures smooth and unrestricted flow of all process fluids. The PF12 meets sterility requirements and is compatible with CIP/SIP while minimizing hold-up volume and hydrostatic shear.
