What is PH tester ?

PH tester is an electronic device used for measuring the PH (acidity or alkalinity) of a liquid (though special probes are sometimes used to measure the pH of semi-solid substances). A typical pH meter consists of a special measuring probe (A glass electrode) connected to an electronic meter that measures and displays the pH reading, and this tester also can test temperature.

Applications : 

PH meter is an easy tool for testing the level of water quality, popular in water deal industry, household, travelling, and etc, especially hydroponics, greenhouse, horticulture and gardening.

Operation 

1. Remove the protective sleeve

2. Clean the Electrode with distilled water and wipe clean the spare water.

3. Press the \"ON/OFF\" button .Turn on the meter.

4. Immerse the PH meter electrode in the solution 

5. Lightly shake the meter, read the data when the numeric stabilized.

6. The temperate displays at the bottom of the screen.

7. Press the \"ON/OFF\" button to shut off the instrument.

8. Clean the electrode with pure water, cover the electrode protective sleeve.

 Calibration

1. Turn on the PH meter

2. Immerse the electrode in PH 6.86 standard buffer solution. (Under the temperature of 25°C)

3. After digital stabilized, press the \"shift\" button for 5 seconds, (The instrument comes into the automatic calibration Status).Wait until the display digital is 6.86pH Then complete PH 6.86 point calibration

4. Clean the electrode with distilled water and dry it with filter paper.  Immerse the electrode in pH 4.00 standard buffer solution

5. After digital stabilized, press \"shift\" button for 5 seconds. Wait until the digital is 4.00 pH Complete the ph 4.00 point calibration.

6. Clean the electrode with distilled water and wipe clean the spare water.Put the electrode in the PH 9.18 standard solution until the data stable,the data will be in 9.17pH----9.19pH. The data is in the range of allowable error.

7. This instrument calibration work is completed after all the steps.

Attention :

The instrument need recalibrate in the following condition.

1. Long time no use or use very long tim
