Submersion/Insertion pH/ORP Sensors - Models 396P and 396PVP
The reference junction provides an electrical connection between the reference electrode and the sample, and helps maintain a stable reference potential, regardless of the change in sample pH. The TUpH reference electrode junction, (the entire plastic tip surrounding the glass pH electrode), maintains a steady reference signal even in the dirtiest of applications because it resists plugging (a common cause of pH signal drift).

The TUpH Reference Technology includes a large area reference junction for minimum maintenance requirements: The reference junction provides an electrical connection between the reference electrode and the sample, and helps maintain a stable reference potential, regardless of the change in sample pH. The TUpH reference electrode junction, (the entire plastic tip surrounding the glass pH electrode), maintains a steady reference signal even in the dirtiest of applications because it resists plugging (a common cause of pH signal drift). This large reference junction area is made of micron sized reference pathways used for ionic exchange so it resists plugging by large particles and will continue to send a steady pH signal, even in the dirtiest of applications. The TUpH reference junction technology has been field-proven for minimum maintenance requirements.

The TUpH helical reference pathway stops reference poisoning. Ions diffuse through the reference pathways and a charge is passed to the reference element. The reference element must be protected from contamination by poisoning ions such as sulfide, mercury, cyanide, and ammonia or else the pH signal will drift. The TupH sensor's long internal helical reference pathway hinders and slows down the rate of contaminants migrating to the reference element therefore providing for a longer sensor life.
