Orion ROSS Ultra® Premium pH Electrodes
The best of the best! The fastest response, highest accuracy, and best reproducibility that you can get with a pH electrode %u2013 plus a 2 year warranty. ROSS Ultra pH electrodes combine all the benefits of the ROSS line with an extended life expectancy and minimized long-term drift. The ROSS reference offers stable, fast results regardless of temperature or sample composition.

Orion ROSS® pH Electrodes
The ROSS line offers precise pH measurements with unmatched stability, reliability, and rapid response regardless of temperature or sample composition. Since ROSS electrodes do not contain silver or mercury, they are well-suited for biological media, food, and pharmaceutical samples where metal ions cannot be tolerated. ROSS Sure-Flow® electrodes have a unique free flowing reference junction with an easy-to-clean design that assures stable, drift-free measurements.

Orion AquaPro Professional pH Electrodes
Low maintenance electrodes with an extended life, fast response, and clog-resistant junction. The double junction reference system prevents silver from coming in contact with the sample, so AquaPro electrodes can be used in samples where metal ions cannot be tolerated.
