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.
