How to maintain the pH pen: If you don't use it for a long time, you can soak the pH pen electrode in pure water in about half a month, and insert it in a disposable cup!
Steps:
1. Remove the protective cover.
2. Turn on the switch located on the battery compartment.
3. Insert the pH meter into the liquid to be tested until the liquid is immersed in the “immersion line”. If possible, allow the solution to immerse slightly above the “immersion line”.
4. Gently stir the solution and wait for about two minutes. Read the displayed value. 5, use is complete. Clean the electrode. Turn off the switch. Put on the protective cover.
Tips:
Clean the electrode with distilled water every time before and after use.
Be careful with the glass probe since it may be a little fragile when you use.
Remember to gently wipe it with a clean, soft cloth when you're done before capping it again.
Open the battery case or replace battery, then need to re-calibrate the meter
