Portable Digital PH Tester Operation

PH MEASUREMENTS: ·Turns on the PH electrode and the temperature sensor .

Turn the meter ON by pressing the ON/OFF key.

·Remove the PH electrode protective cap, then submerge the PH electrode and the temperature probe into the sample to be tested.

·Stir gently and wait for the stability symbol. The display will show the PH value automatically compensated for temperature.

·After use, rinse the electrode with clean water, replace the electrode protective cap.

ORP MEASUREMENTS: Oxidation Reduction Potential(ORP) measurements provide a quantification of the oxidizing or reducing power of the sample tested.

·Connect the ORP electrode to the BNC connector.

·To enter the〝mV〞mode turn the instrument ON and press the mV key until the display changes to mV.

·Then submerge the ORP electrode into the sample to be tested and allow time for the reading to stabilize.


·Make sure the temperature probe is connected to the meter.

·Turn the instrument ON and press the ℃ key to select the temperature mode.

·Dip the temperature probe into the sample, allow the reading to stabilize and read the temperature value.

What is 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.
