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
