A combination reference electrode for corrosion monitoring; a manganese dioxide 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 mixed metal oxide (MMO) coated titanium outer tube.
The MMO titanium tube is effectively a back-up pseudo reference electrode in the unlikely event that the main electrode fails but can also be used for current measurement.
Reference electrode type:
RB15 manganese dioxide and mixed metal oxide (MMO) coated titanium
+175mV (+/- 20mV) wrt saturated calomel electrode for the RB15 reference electrode
+/- 3mV over a 24 hour period
