Mudder 0.01 pH Accuracy Digital pH Meter with Automatic Calibrate Function, Water Quality Tester with ATC, 0.00-14.00 pH Measurement Range

How to Use

Remove the protective cap
First clean the electrode with distilled water, then put it aside until it's dry
Immerse the pH meter electrode in solution being tested up to the minimum immersion level and not be over the maximum immersion line
Turn on the pH meter by "ON/ OFF" button
Stir gently and wait until the display stabilizes, and you can read the value
After use, switch it off, use the distilled water to clean the electrode and replace the protective cap

Recalibration

In normal, this pH meter is factory calibration, and no need to recalibrate. Recalibration is required in the following conditions:
- Lengthy periods of inactivity
- Very frequent use
- The testing accuracy requirement is very high
- The "CAL" (calibration) button was pushed and electrode exposed to air for extended period of time

Tips

The glass bulb of the electrode is fragile. Treat it carefully. Don't touch it by hard tools and fingers. Suck the water on it gently when cleaning
Clean the electrode with distilled water every time before and after use
Open the battery case or replace battery, then you need to recalibrate the meter
