LD15/MMO Datasheet

A combination reference electrode for corrosion monitoring; a silver/silver chloride/0.5M KCl reference electrode with mixed metal oxide (MMO) coated titanium outer tube.

Some specifications require the use of combination reference electrodes for corrosion monitoring. These are usually reference electrodes with a mixed metal oxide (MMO) coated titanium outer tube.

The MMO titanium tube is effectively a backup pseudo reference electrode in the unlikely event that the main electrode fails and can also be used for current measurement.
