Description
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
Typical Applications
Ultrafiltration
Chromatography
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.
