pH combination electrodes with Pt1000 temperature sensors cover a wide range of industrial applications. Depending on the design, they are suitable for use in media with low conductivity, stable chemical environments or pure aqueous solutions.
pH combination electrodes with Pt1000
Electrodes with liquid electrolyte and platinum junction enable reliable operation in media with low conductivity and help reduce the risk of clogging or poisoning.
Variants with a KPG annular gap junction provide high chemical resistance and are ideal for stable media. The controlled electrolyte outflow ensures long service life and consistent measurement performance.
For applications in pure aqueous solutions, electrodes with a triple ceramic junction offer faster response times while maintaining low maintenance requirements.
- Wide application range for different process conditions
- High chemical resistance and long lifetime
- Reliable temperature compensation with Pt1000 sensor
The pH combination electrodes with Pt1000 feature an integrated temperature sensor, a VP screw plug head, and a glass shaft (12 mm diameter), with variants offering different glass types, junctions, membranes and measuring ranges:
