First Usage
Condition the pH electrodes by immersing it in pH electrode protection solution for 1 hour before using. If the pH electrode protection cap is dry (may cause white crystals), add storage solution in the cap and soak the pH electrode for 1 hour.
Accuracy
ST20 is 0.01pH resolution and 0.05pH accuracy pen meter. Each ST20 pen meter is factory calibrated. You may need to calibrate the ST20 regularly to ensure accuracy.
pH Measurement
Remove the protection cap, rinse the pH electrode glass bulb with pure water (distilled water), and wipe clean. (Glass bulb is fragile, be careful, do not scratch it.)
Maintenance
Clean the electrode after test and cover the protection cap, be sure storage solution is not dry in the cap. Harsh samples may short the pen meter life time, such as sticky, dirty or oily liquids. The meter use button battery 1.5V (AA)*4 , replace all the batteries when the display fade or not turn on.
