Endress+Hauser Tophit CPS491

Analog non-glass pH sensor

Analogue ISFET sensor for long-term and stable pH measurement in heavily polluted environments. Field-effect transistor with a change in the concentration of ions.

ISFET electrode for heavily polluted media in chemical processes, paper or paint production.

ISFET

- process applications - non-glass, break-proof - low temperatures - min. conductivity >500ВµS/cm - emulsions, suspensions, organic solvents

- rapid response at low temperatures - stabilised gel insensitive to contamination - lower amount of maintenance required than with glass - overhead installation

pH 0-14

- open aperture - double gel reference

- all shaft lengths with temperature sensor - advanced gel technology
