Hi
Please i would like to know how to test the zinc anode priore to be installed to protect the bottom plate of an above ground storage tank.

thank you in advance
 
Depending on the size of the anode, put it with a silver/silver chloride reference cell in a seawater / 3% NaCl solution bath. Connect the anode to the negative terminal of a multimeter, and the reference cell to the positive. You should get readings between -980mV to -1050mV.
