Groline Electrode Cleaning solution - 500mL bottle

pH and TDS electrodes should be cleaned frequently (every 1-4 weeks, depending on use) to prevent premature failure and maintain accuracy.

To use the Hanna Electrode Cleaning Solution, simply put a small amount (enough to cover the probe) in a Dixie cup or shot glass and let the electrode sit in the solution for up to 24 hours, then rinse. Or, choose a single-use sachet for field use.
