Welcome to the Conductivity Measurement Frequently Asked Questions Page. On this page you can find answers for many general questions.

1. How do I clean my conductivity electrode?

Clean cells with mild liquid detergent and/or diluted nitric acid (1% wt) by dipping or filling the cell with solution and agitating for 3 to 4 minutes. Diluted HCl (hydrochloric acid) or H₂SO₄ (sulfuric acid) may also be used. When stronger cleaning is needed, try concentrated HCl mixed into 50% isopropanol (rubbing alcohol). Rinse the cell several times with distilled or deionized water and recalibrate before use.
