Hanna Instruments HI-1211T PEI-Body Combination pH Electrode
The combination PEI-body pH electrode is designed for industrial applications with features such as a PTFE junction, high temperature glass, and T-type connection.
With its durable design, you can count on this electrode to stand up to your process environment.
- pH electrode with renewable cloth junction
- High temperature glass can stand up to the effects of elevated temperatures leading to longer probe life
- Built for everyday, demanding use in industrial applications
Key features – HI-1211T
- Combination electrode - Single combined electrode that has both sensing and reference components for added convenience.
- High temperature glass formulation - High temperature glass can stand up to the effects of elevated temperatures leading to longer probe life.
- PTFE junction - The electrode has a unique clog resistant junction that enhances both probe life and accuracy.
- T-type connector - Designed by Hanna to take advantage of both PG 13.5 thread and screw cap. The PG 13.5 thread ensures proper in-line installation while the screw cap allows for maximum versatility making it possible to connect a cable of different lengths.
- PEI body - PEI bodied electrodes are rugged and suitable for noncritical applications that require a very good combination of chemical, mechanical, and thermal resistance.
- Double junction technology with gel polymer filling - Ensure long electrode life and reliability in harsh environments.
