pH Electrode Characteristics
The output of pH electrode is Millivolts,and the pH value of the relationship is shown as follows (25 ℃):
Use the pH Meter

Step to Use the pH Meter
Cautions:
Please use an external switching power supply,and the voltage as close as possible to the +5.00V. More accurate
the voltage, more higher the accuracy!
Before the electrode in continuous use every time,you need to calibrate it by the standard solution,in order to
obtain more accurate results.The best environment temperature is about 25 ℃,and the pH value is known and
reliable,close to the measured value. If you measure the acidic sample, the pH value of the standard solution should
