pH Electrodes, SenTix®
: WTW
These proven and tested pH electrodes are easy to use and offer high quality and precision.
- Electrodes with gel electrolyte and a plastic body are robust and shock-proof, the membrane glass is safeguarded by a protective shield
- Electrodes with liquid electrolyte: Capillary-effect of the platinum wire guarantees constant outflow and prevents contamination by precipitates or even dirt
- SenTix® HW and HWS electrodes: Electrolyte flow speed can be adjusted for optimal use
Optimised membrane glass guarantees quick measurement even at low temperatures. The easy to use fill-hole cover prevents electrolyte from leaking out during storage.
* with integrated temperature probe (NTC 30 KOhm).
