The right probe for your application.

To meet your analysis needs, Radiometer Analytical reference electrodes are available with a variety of reference systems and liquid junctions. There is a Radiometer electrode for every application.

Unique Red-Rod technology provides a reproducible, fast and accurate response.

The symmetry formed by the internal and external Red-Rod reference elements means that the iso pH is the same as the zero pH which provides highly reproducible results and a fast, accurate response, even when temperature fluctuations occur.

Know that you have the right answer.

Red-Rod electrodes provide a stable signal fast by protecting the reference elements from light interference. The Red-Rod saturated KCl salt-bridge also aids in creating a stable liquid junction potential.

Avoid problems with your measurement, even in challenging samples types.

The Red-Rod system creates a trouble-free liquid junction. The Red-Rod encapsulation of reference elements means no silver ions and therefore less risk of clogging when measuring in challenging sample matrices.

Measure over a wide temperature range.

The Red-Rod reference system enables use over a wider range of temperatures than for most pH electrodes.
