Field of application
Tophit CPS441 is the analog high performer for media with low conductivity or a high content of organic solvents. Designed for fast response, it accurately measures even in fast-changing medium compositions. Its unbreakable shaft ensures absolute safety of your products.
Media with a high amount of organic solvents or very low conductivities:
Chemical industry including precipitation reactions or dispersions (pressurized version)
Power plants, e.g. boiler feed water
Life sciences, e.g. water for injection
With 3A, ATEX, FM and CSA approval suitable for hygienic applications or hazardous areas.
Benefits
Unbreakable for highest product safety
Resistant to poisoning thanks to constant refilling of KCl bridge electrolyte and separate reference lead
Suitable for sterilization
Low maintenance thanks to long calibration intervals
