What is the Correct Way to Check Repeatability in Balances?

This range is important for the efficiency of an electrode, out of this range, water gets electrolysed, spoiling the electrical energy that is intended for another electrochemical reaction.

Materials

• Platinum (very expensive)
• (boron-)doped CVD diamond films on titanium or niobium: 3.5 - 1.5 V (undoped, diamond does not conduct electricity)
