Hanna Instruments HI-1090T Process pH electrode, T-Type Connector
This combination glass-body pH electrode is designed for industrial applications with features such as a ground glass 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.
- Combination glass-body pH electrode.
- Low temperature glass for fast stabilisation and more accurate results at lower temperatures.
- Built for everyday, demanding use in industrial applications.
The HI-1090T is a glass bodied double junction pH electrode with T-type connector for use with process instrumentation.
Combination electrode - Single combined electrode that has both sensing and reference components for added convenience.
General purpose glass formulation - General purpose glass provides the best response over the entire pH range and can be used for a wide range of applications.
Ground glass junction - Commonly used junction type as glass with the correct expansion co-efficient is easily welded to the glass body allowing for proper electrolyte flow.
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.
Glass body - Glass body electrodes are easier to clean, can withstand high pressure and high temperature applications, and offers high resistance to aggressive chemicals.
Double junction technology with gel polymer filling - Ensure long electrode life and reliability in harsh environments.
