Model UR Regular Underground Reference Electrode by EDI
Farwest is a stocking distributor for the EDI line of reference electrodes, coupons and similar cathodic protection products.
Industry Standard with 15-Year Design Life
Description
The Model UR is designed for permanent installation to obtain accurate potential measurements on buried structures. It is the best choice for those applications where easy installation is possible, such as an open hole or trench. For those situations where there is limited access, the EDI Model US is recommended. A Cu/CuSO4 element should be used in low chloride soils (<500 ppm), while a Ag / AgCl element is recommended for high chloride soil (>500 ppm) in order to obtain the longest possible life. Further information is available from Farwest.
