The model identification used for EDI products consists of three groups, eg: CB-AGG-LW. The first group defines the basic product while the second and third groups define the various options associated with that product. This selection guide briefly describes products within the EDI C Series. For further information, see the individual data sheets.
C Series products are designed for use in reinforced concrete and include references with Ag/AgCl elements, graphite, rebar or MMO probes, and potential wells. EDI also designs and builds custom products for concrete applications to fulfill special requirements.
CB
Permanent Embedded Reference: This Ag/AgCl reference
is designed specifically for use in reinforced concrete. It is encased in
a bag containing a compliant backfill to ensure good bonding to the structure
and features shielded cable lead wires to eliminate electronic interference.
CM
Marine Concrete Reference This new Ag/AgCl reference
electrode has been optimized for use in concrete saturated with seawater.
It offers the long term stability of our Model CB at a price comparable
to graphite probes. Applications include all marine concrete structures
including seawalls, pilings and docks
Graphite
Probes: These are used for making relative potential
readings.
MMO Probes are also used for relative potential readings.
Rebar Probes: are used for corrosion rate monitoring by the linear polarization resistance technique. The rebar probe is the working electrode while the rebar net serves as the counter electrode. They are frequently used to monitor reinforced concrete with inhibitors and sealers.
CW
Potential Wells: These devices allow accurate reproducible potential
readings to be made with portable reference electrodes by eliminating the
errors normally associated with surface readings. They also permit readings
to be made through surfaces covered with membranes or sealers. Potential
wells are available in two styles: Short
which are used for measurements directly beneath the well and Long
which have extensions and are used for measurements at a remote location.
CX
Custom Products: The CX model designation is used for
special or unusual customer requirements.
