ROSS pH Electrodes

Accuracy, precision and reproducibility for pH measurement

For more than 30 years, ROSS pH electrodes have been helping to provide accuracy, stability and rapid response. Compared to conventional electrodes, the proven ROSS reference system exhibits stability in measurements, faster response, greater accuracy and precision when measuring samples that vary in temperature, or when calibrating in temperatures that differ from your samples.

ROSS pH electrodes are available in a variety of styles such as the clog free Sure-Flow junction, glass or epoxy electrodes, flat surface, semi-micro, micro, and spear tip designs.
