Analog ISFET sensor with reference electrode. Filled with liquid KCl for measuring pH in protective media.

ISFET electrode for the chemical, life sciences and food industries.

Measuring principle

ISFET

Application

- Special applications with high requirements with regard to accuracy and speed - non-glass, break-proof - low temperatures - rapidly changing composition of media - highly clogging media - low conductivities

Characteristic

- Ion sensitive field effect transistor (ISFET) technology - overhead installation - rapid response at low temperatures - lower amount of maintenance required than with glass - 3A

Measurement range

pH 0-14

Measuring principle

- Ceramic diaphragm - liquid lead

Design

- All shaft lengths with temperature sensor
