Electrical stability is the most important aspect of any reference cell. Permacell Plus has unsurpassed stability, with a thirty-year design life, and an accuracy level of within five millivolts.

The system’s impressive performance is due in large part to its reference cell element. The cell is composed of a 99.99% pure copper element, which is housed in a specially designed porcelain cup.




An inside track within the cup greatly reduces the chance for ion intermixing, and ensures cell purity.Surrounding this cup is a thixotropic stabilized gel backfill. This backfill material greatly reduces the cell’s electrical resistance to the earth and does not require moistening.

Permacell Plus can be used to measure the electrical potentials on all types of buried structures. It is offered with either pole- or flush-mount test stations, and is ideally suited for structures, such as underground storage tanks, which are located under pavement or other impediments. The system is not recommended for use in areas with high chloride concentrations.
