An anodic current meter can be used to measure the current and evaluate the anode time life. The measured value
shall be higher than 0,3 mA.
Attention: For a correct measurement, the tank must be full with water! The electrical connection must be ensured
after measurement.

Anyway, a visual inspection is strongly recommended every 2 year, in order to identify an eventual start of a crack
in a part of the anode, or eventually the calc deposition over the magnesium anode surface which will decrease the
anodic current as well, but will also disable the protection function of the anode.
The visual inspection should include a material surface, weight, diameter and length changing control.
