ProcessLine pH combination electrodes with Pt1000 temperature measurement are designed for challenging process applications involving suspended solids, slurries, emulsions and viscous media. Their optimized reference systems help ensure reliable measurement, even under difficult operating conditions.
ProcessLine pH with Pt1000
Electrodes with a 2-hole junction are particularly suitable for media with an increased risk of clogging caused by suspended solids 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.
- Suitable for suspended solids, slurries and emulsions
- 2-hole junction and PTFE diaphragm options
- Integrated Pt1000 temperature sensor
The ProcessLine pH combination electrodes with Pt1000 feature a screw plug head (ATEX II 1/2G), a glass shaft (12 mm diameter) and an integrated Pt1000 temperature sensor, with variants available for different process conditions, junction designs and glass types.
