pH Electrodes
Our extensive assortment of quality pH electrodes, sensors, and probes are designed to make your complex measurements routine, reliable, and accurate in both the lab or in the field. They are available in a variety of body materials, body styles, and sample requirements. Digital probes have built-in temperature sensors and will alert the user when recalibration is needed. These probes have rugged bodies and long integrated cables for convenient use in a variety of scenarios.
Combination pH electrode, Orion™ 815600 ROSS™
Supplier: Thermo Orion
ROSS pH electrodes offer unmatched benefits that users will not find in any other pH electrode. Compared to conventional electrodes, the proven ROSS reference system exhibits superior stability in measurements, faster response, greater accuracy and precision when measuring samples that vary in temperature or when calibrating in temperatures that differ from the samples.
