P.H. Meter

Description

Before measuring, remove the safety cap, if crystals appear under it, this is not a cause for concern this is normal with pH-meters electrodes. The problem will disappear after rinsing the electrode with cleaning liquid/water. Turn on the pH meter with the button at the top of the device and dip the electrode to the maximum permitted level. Gently stir the meter in the solution and wait for the reading to stabilize.
After use, rinse the electrode with water to avoid contamination. Store the meter with a few drops of electrode storage fluid in the safety cap.
DO NOT USE WATER TO STORE THE ELECTRODE
Large differences in readings can be due to the need for calibration, dry electrode or weak batteries.
