For more than 40 years, long-lasting ROSS 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.
