Model UC1, Style A, Underground CP Coupon by EDI

Description

Model UC1 does not have an AC coupon.

Style A is installed at the base of a test station riser as shown in drawing UC-9. A zinc reference electrode can be installed in the housing as an option.

• Patented 10 sq. cm. concentric coupon removes nearly all soil IR drop error in current-on measurements.
• Optional 1 sq. cm. coupon for AC current density measurements.
• Easily fitted to the base of a test station riser or used in a stand-alone configuration when fitted with the optional internal zinc reference electrode.
• Potential measurements are made through the riser tube with either portable or permanent reference electrodes.

The Model UC Underground Cathodic Protection Coupon is fitted to the base of a test station riser. It is designed to allow essentially IR-Drop free measurements with CP current on. The amount of IR-Drop error included in a current-on measurement is negligible and can therefore be ignored in routine measurements. Refer to NACE paper 05039, available on our web site, for quantitative performance data. Many factors contribute to the magnitude of IR-Drop error at any particular site; therefore it is recommended that each installation be calibrated separately.
