PerpHecT® Electrodes offer the most accurate pH measurements possible when using Orion's new PerpHecT pH meters. These meters utilize the patented digital LogR® technology. Silver/Silver chloride electrodes are widely used because of their accuracy and broad temperature range (0-100°C). But silver in the internal filling solution can react or precipitate with components of some samples, such as protein, sulfide, halides, or tris buffers, causing junction potential problems.

ROSS Electrodes offer stable, fast results regardless of sample temperature or composition. If you are measuring samples that vary in temperature, or differ in temperature from your calibrating buffers, the ROSS Electrode's special internal system provides superior measurement stability, faster response, greater accuracy, and more reproducible results than conventional electrodes. With ROSS Electrodes you avoid long-term drift or inaccurate readings, even in samples that vary in temperature; while conventional electrodes produce unstable results until they reach thermal equilibrium with the sample.

Conventional electrodes can leach metal ions into the filling solution and subsequently into the sample. ROSS® Electrodes do not contain silver or mercury to react with the sample or clog the ceramic frit. Use ROSS pH Electrodes where trace amounts of metal ions in such samples as biological media, foodstuffs, and pharmaceuticals cannot be tolerated. pH range is 0-14.
