February Featured Product of the Month Model UC

Our concentric coupon, Model UC, is designed to make potential measurements that are substantially free of IR-drop error without either interrupting current or disconnecting the coupon. It is known as a Concentric CP coupon because the potential measuring ports are located in the center of the coupon, well away from IR drop fields in the environment. This design is preferred for locations where interrupting currents or disconnecting the coupon to make measurements is not practical. It is particularly well suited for use with remote monitoring units. EDI’s concentric CP coupon may be installed at the base of a test station where access through a soil tube is used for making potential measurements. This product may also be ordered with a contained packaged zinc reference electrode which eliminates the need for access through a soil tube. Either version can be ordered with a 1 sq. cm. coupon for measuring AC current density.
