RI01

The RI01 ring is our high-precision standard measuring probe for surface and interfacial tension using the Du Noüy ring method. The wire ring made of a platinum-iridium precious metal alloy is ideally wettable; the hardness of the iridium makes the measuring probe especially robust. The ring geometry is only connected to the shaft at two junctures, so that any disturbing influences on wetting are negligible.

A simple clamping mechanism allows especially fast insertion of the ring. Its safe storage is assured through a high-quality protective box provided.

An RIC01 version of the ring with a certificate from an independent testing institute is also available.
