Operation
1.Remove the protective cap of electrode.
2.First rinse the electrode with distilled water, and suck it with filter-paper.
3.Turn the meter on by pressing the key.
4.Immerse the ph meter electrode in the solution to be tested.
5.Wait for the reading to stabilize.
6.After use, rinse the electrode with water to minimize contamination. Turn the meter on by pressing the key. Replace the protective cap after use.
PH Calibration
1.Immerse the electrode in pH 6.86(under the temperature of 25) standard buffer solution of phosphate, and gently shake it.
2.Allow the reading to stabilize and with a small screwdriver turn the calibration trimmer inside the battery compartment until the display shows is corresponding the calibration solution.
3.Immerse the electrode in pH4.01 or pH9.18 the standard buffer solution of borax.
4.After one minute, until the buffer solution value is corresponding the measurement temperature is obtained.
Battery Install
If the hydroponic pH meter can not be switched on or the display fades, To change batteries. Open up the battery case and replace batteries. Pay attention to the polarity of battery.
PH: pH is a measure of acidity or alkalinity.
The hydrogen ion concentration index ((hydrogen ion concentration)) refers to the ratio of the total number of hydrogen ions to the amount of total substances in the solution. It is commonly referred to as "pH", not "pH". For the determination of hydrogen ion activity index, the qualitative method can be determined by using pH indicator and pH test paper, while the quantitative pH measurement needs to be measured by pH meter.
