Tophit CPS441 is a high-performance analog electrode for measuring media with low conductivity and highly concentrated organic solvents. Even in applications where the medium composition changes rapidly, the electrode's fast response ensures high process safety. Its shatterproof sensor shaft ensures medium safety.
Benefits
Resistant to breakage and cracks, increasing measurement safety
Continuous KCl electrolyte replenishment and a separate reference lead give the electrode its poison-resistant properties
Suitable for sterilization processes
Long calibration intervals and low maintenance
Application
For measuring highly concentrated organic solvents or media with low conductivity:
Pressurized version for measuring precipitants and dispersants in the chemical industry
Power plants, e.g. boiler feedwater
Life sciences, e.g. water for injection
Certified to 3A, ATEX, FM and CSA, suitable for hygienic measurement applications or hazardous (explosion-proof) areas
