High surface area prevents loss of contact with host concrete

Chloride free - no release of aggressive salts

Excellent polarisation characteristics - stable potential when current is drawn

Compact unit facilitates simple installation
A common method of assessing the corrosion state of reinforcing steel is to measure the steel potential using a reference electrode.
CPT manufacture a refernce electrode, MN15, which is buried in a small hole formed in the concrete surface. This can then be used to measure the steel potential either manually, using a simple voltmeter, or remotely using a datalogger
.The MN15 refernce electrode offers significant advantages versus conventional electrodes:
