HQd IntelliCAL Probes, IntelliCAL PHC729 RED ROD pH Electrode for Surface Measurements Cat. No. PHC72901

Symmetry between internal and external Red Rod reference elements ensures that the iso pH is the same as the zero pH, providing highly reproducible results and a fast, accurate response, even in samples with fluctuating temperatures. Red Rod technology also provides a stable signal by protecting the reference elements from light interference, and the saturated KCl salt-bridge aids in creating a stable liquid junction potential. Red Rod technology provides fast, accurate and reproducible measurements Red Rod reliability when measuring challenging samples over wider temperature ranges IntelliCAL™ digital probes can be moved between meters without the need to re-calibrate or re-enter measurement settings IntelliCAL™ digital probes provide ultimate traceability in measurement history
