These pH electrodes are designed for applications in the chemical industry where minimum contamination and reliable measurement are essential. High chemical resistance ensures stable operation, even in demanding process conditions.
Digital pH electrodes with Memosens
Electrodes with a KPG annular gap junction allow a controlled and slow outflow of electrolyte. This design minimizes contamination while ensuring long service life and stable measurement performance.
For applications in pure aqueous solutions where faster response is required, variants with a 3 x ceramic junction are available. These provide improved response behavior while maintaining low maintenance requirements.
All models are equipped with Memosens technology, enabling inductive, contactless signal transmission. This ensures reliable measurements even in harsh industrial environments.
- Low contamination design for sensitive chemical processes
- Long lifetime due to controlled electrolyte release
- Memosens technology for safe and interference free transmission
The digital pH combination electrodes with Memosens feature an integrated NTC 30K temperature sensor and a glass shaft (12 mm diameter), with variants offering different glass types, junctions, membranes and measuring ranges.
