Digital ProcessLine pH combination electrodes with Memosens technology are designed for demanding process applications involving suspended solids, slurries, emulsions and viscous media. Their optimized reference systems help ensure reliable measurement, even under challenging operating conditions.
ProcessLine pH with Memosens
Electrodes with a 2-hole junction are particularly suitable for media with an increased risk of clogging caused by suspended solids, slurries or deposits. The robust design ensures stable measurement and long service life in demanding process environments.
For chemically aggressive media and applications involving organic solvents, versions with a dirt-repellent PTFE diaphragm are available. These variants provide excellent chemical resistance and minimize fouling.
If hydrofluoric acid (HF) is present, electrodes with A glass should be selected. Please note that both fluoride concentration and pH value are critical factors for electrode lifetime and performance.
- Memosens technology for secure digital signal transmission
- 2-hole junction and PTFE diaphragm options
- Suitable for suspended solids, slurries and emulsions
The ProcessLine pH combination electrodes with Memosens feature a Memosens® screw plug head (ATEX II 1/G), a glass shaft (12 mm diameter) and an integrated NTC 30K temperature sensor, with variants available for different process conditions, junction designs and glass types.
