AI1166 Electrode Cleaning Solution 8oz. by Apera

Apera Electrode Cleaning Solution is made for removing tough contaminants on pH and conductivity electrodes such as grease, dairy deposits, beverage stains, and other complex or sticky matters.

After using the cleaning solution, the sensitivity of your pH glass membrane can be restored at a certain level, which will render faster response time and higher accuracy.

How to use?

• Soak the electrode in the cleaning solution for 30 min to 2 hours.
• Rinse off the electrode with distilled or deionized water.
• For pH and ISE electrodes, soak in storage solution for at least 2 hours. For conductivity electrodes, go to step 4.
• Calibrate the meter and you are good to go.
