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 by sample conductivity
  • 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 conductivity probe ACS60 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 ACS60 probe 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 probe's lifetime.

Features
Benefits
