General Description

Some specifications require the use of combination reference electrodes for corrosion monitoring. These are usually silver/silver chloride 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.


Reference electrode type:

LD15 silver/silver chloride and mixed metal oxide (MMO) coated titanium


-15mV (+/- 10mV) wrt saturated calomel electrode

Stability :

+/- 3mV over a 24 hour period
+/- 10mV over 20 years

Design Life:

30 years for the LD15 reference electrode
100 years for the MMO Titanium

Silver element :

99.99% purity

Housing type :


Junction Type :

Cementitious >175mm2

Dimensions :

Approx . 20mm x 100mm

Cable type :

Twin core to suit client requirements with heat 
shrink sleeving to seal the cable.

Quality control :

Calibrated under laboratory conditions.
Unique identification numbers.
Calibration certificates for each contract.
