Gel-Glass Details

The Gel-Glass pH Sensor is designed for consistently reliable pH measurements. It consists of   a glass body and a ceramic diaphragm (junction) for contamination and corrosion resistance. This pH electrode is pre-filled with gel electrolyte to significantly reduce or eliminate maintenance in busy laboratories. With easy operation, quick stabilization, and a sealed reference system, the Gel-Glass pH probe provides everyday value in pH measurements.

Reduce downtime with pre-filled no-maintenance gel electrolyte.

Durable materials resist chemical wear and contamination.

 Everyday value and quick stabilization in general laboratory.
