A Use natural seawater or artificial seawater conforming to GB/T 17848. Sea mud is natural sea mud or a simulated electrolyte with a resistivity of 30–50 Ω·cm. Diluted seawater has a resistivity of 70–80 Ω·cm. Seabed sand and gravel has a particle size of 8–40 mm and a medium resistivity of 40 Ω·cm.
B The reference electrode is a saturated calomel electrode.
