- Overview
- Comments
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.
Measuring principleISFET
Application- process applications - non-glass, break-proof - low temperatures - min. conductivity >500ВµS/cm - emulsions, suspensions, organic solvents
Characteristic- rapid response at low temperatures - stabilised gel insensitive to contamination - lower amount of maintenance required than with glass - overhead installation
Measurement rangepH 0-14
Measuring principle- open aperture - double gel reference
Design- all shaft lengths with temperature sensor - advanced gel technology
