High performance Red Rod technology now available for the digital HQD platform
IntelliCALⓇ PHC735 is a digital combination pH electrode with built-in temperature sensor. The PHC735 is a pH refillable electrode with a high flow annular ceramic porous reference junction embedding the RedRod technology to deliver exceptionally fast, stable, and accurate response times for accurate measurements within a wide temperature range. Thanks to its high flow annular ring reference junction this high performance laboratory glass pH electrode is ideal for measuring pH in “dirty” samples, including wastewater, food and beverage applications. A 59-mL bottle of saturated KCl Electrode Filling Solution is included with the probe. The PHC735 is not suitable for use with organic solvents or high alkaline sample types.
Benefits
Red Rod technology provides fast, accurate and reproducible measurements
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 reliability when measuring challenging samples over wider temperature ranges
Red Rod encapsulation of reference elements means no silver ions and less risk of clogged junctions. It also enables accurate measurements over a broader temperature range than standard electrodes.
IntelliCAL digital probes can be moved between meters without the need to re-calibrate or re-enter measurement settings
Ideal for a multi-user environment with multiple HQD series laboratory and portable meters.
IntelliCAL digital probes provide ultimate traceability in measurement history
Stored time and date stamp for each measurement, operator and sample ID, calibration history, parameter, and probe serial number
Wide temperature range up to 100 °C
