Low-maintenance pH electrodes with integrated temperature sensor
Xylem's WTW SenTix® 41-47 pH electrodes feature a durable plastic shaft and a cylindrical membrane, and are ideal for both laboratory and field use. The integrated temperature sensor ensures precise readings by compensating for temperature variations, while the gel electrolyte provides low-maintenance operation without the need for refilling.
- Standard electrodes with gel electrolyte and built-in temperature sensor for pH measurement in lab and field
- Maintenance-free gel reference system over the entire product life
- Automatic temperature compensation
- Robust plastic shaft - excellent for lab and field use
- Integrated temperature sensor
- Cylindrical membrane is robust and offers quick response times
- Fiber diaphram prevents clogging and ensures stable measurements
The Sentix® 41-47 pH electrodes with their plastic shaft are particularly suitable for mobile (field) pH measurement. The cylindrical shape of the membrane is robust and the fiber diaphragm prevents clogging. With the gel electrolyte filling, these electrodes are low-maintenance and do not need to be refilled.
The SenTix® 41-47 are particularly suitable for the following applications:
