Water Hardness Tester pH Meter Water Quality Analysis

The appropriate PH of water is essential for the functioning of many areas of life. The correct pH ensures that the water reacts correctly with the other ingredients added to it.

HOW TO USE:

Remove the protective cap.

First rinse the electrode with distilled water and wipe it with filter paper.

Turn on the counter by pressing the ON/OFF button.

Immerse the pH meter electrode into the test solution (it cannot be higher than the immersion line).

Stir gently and wait about 30 seconds for the reading to stabilize.

When finished, clean the electrode with clean water, turn off the meter by pressing the "ON/OFF" button.

Always put on the protective cap after use.

CALIBRATION:

Turn on the pH meter.

Dissolve pH 6.86 buffer solution in 250 ml distilled water (below 25).

Press the "CAL" (calibration) button for 5 seconds and release - The display will start flashing 6.86 - Wait until the display stops flashing.

Rinse the electrode with distilled water and dry with filter paper.

Immerse the electrode in another pH 4.00 solution.

Press the "CAL" button for 5 seconds, then press and immediately release a second time - Reading will flash 4.00 - Wait until the display stops flashing.

Rinse and dry the electrode with distilled water as before.

Repeat the operation to calibrate the pH 9.18 solution.
