Use
Switch on the device using the ON/OFF button, remove the protective packaging of the electrode and place it in the liquid you want to test (observe the maximum immersion level). After the values stabilize, you can read the pH value and the temperature value. After use, turn off the device using the ON/OFF button, clean the electrodes and put them in the protective case with a few drops of distilled water. Battery replacement - if the "Eb" symbol appears on the screen, it is necessary to replace the battery. The device must be recalibrated if the electrode has not been used for a long time or if we want maximum accurate results.

ATTENTION!

Never immerse the probe in highly concentrated acid or alkali! (E.g. undiluted pH minus liquid)
Never use the device to test hot liquids, as this can damage the probe!
A possible bubble in the probe can also be caused if the probe has been exposed to high temperatures. The air bubble itself does not cause a problem, because it rises up during measurement, so it stays away from the sensor part.
