ACS60-35 Conductivity Probe

Advanced Conductivity Probe

Knowing the conductivity of liquid samples is a key parameter to control product quality throughout the production process. The optek ACF60 conductivity probe fulfils technical requirements of international regulations for reliable measurements ensuring quality and consistency.

Used For:

  • Conductivity (DIN EN 27888 / ISO 7888 & ASTM D1125):
    • 0 - 850 mS/cm
  • User defined concentration measurement
  • Conductivity monitoring
    • for fermenter / vessel control
    • of CIP processes
    • in TFF / Ultrafiltration
    • of heat exchanger
    • of pure, drinking and treatment water
    • for interface detection in food and beverage

The ACS60 conductivity sensor features a superior six-electrode, fourpole design. The 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 C800 or C8000 universal converter and ACS60 conductivity sensor allows a wide dynamic range from 0 – 10 μS/cm up to 0 – 850 mS/cm with the same sensor.

Features
Benefits
