Model CP-GRA - Graphite Probe

Model CP-REB - rEBAR Probe

Typical Application:

Bridge decks and substructures, parking garages, docks, and buildings

Featuring:

Reinforcing steel bar element
Used for corrosion rate monitoring by linear polarization resistance

Housing Specifications ¾ in. (2 cm) dia. x 3 ½ in. (9 cm) long Shipping weight – ½ lb (¼ kg)	Element Specifications #4 deformed reinforcing bar (rebar)
Termination SWnnn - #14 AWG HMW/PE, nnn ft. long 2Wnnn - two #12 THHN/THWN, nnn ft. long	Element Types REB –rebar steel
	Model Designation Specify as EDI Model CP REB SWnnn nnn = Length of lead wire

Application Notes:

The Model CP-REB should be installed the same distance below the surface as the outer rebar net. It is often used in conjunction with an Ag/AgCl reference electrode such as the EDI Model CB-AGG for linear polarization resistance measurements of corrosion rate. In this application, the rebar probe is the working electrode while the rebar net is the counter electrode. By periodically monitoring corrosion rate, the efficacy of sealers, membranes and inhibitors can be verified.
