Field of application

Ceraliquid CPS41 is the analog high performer for pH measurement in harsh chemical applications and media with low conductivity or a considerable content of organic solvents. The sensor is designed for fast response guaranteeing you high process safety even in applications with quickly changing medium compositions.

Media with very low conductivities or a considerable amount of organic solvents or alcohols and fast changing media:

  • Chemical industry

  • Power plants, e.g. boiler feed water

  • Life sciences, e.g. water for injection

With ATEX, FM and CSA approval for use in hazardous areas.

Benefits

  • Resistant to poisoning due to constant refilling of KCl bridge electrolyte and separate reference lead

  • Applicable at very low conductivities (= 0.1 µS/cm) thanks to liquid KCl electrolyte

  • Suitable for cleaning in place (CIP) and sterilization in place (SIP)

  • Perfectly suited for quickly changing media: Combination of liquid KCl electrolyte and ceramic diaphragm enables fast response time

Videos

  • The pH-value of a liquid can be calculated using the potentiometric measurement principle. This video shows what it is about and how this measuring principle works.
