H-1 anodes are cast to meet ASTM B843, Alloy AZ63. This unique composition allows for even current output and efficient protection. These anodes produce an open circuit potential of 1.53 – 1.55 volts, and have a current efficiency of 45 to 55%, when tested in accordance with ASTM-G97 procedures. H-1 anodes are recommended for use in low resistivity soils (typically below 2,000 ohm-cm). Their lower current output allows these anodes to operate longer than high potential anodes in more conductive environments.
