Product Description
Specification:

*measure range: 0.00pH - 14.00pH

*resolution: 0.01pH

*accuracy: +/- 0.01pH

*power supply: 2*1.5V (keep using more than 500 hours)

*operating temperature: 0℃ - 80 ℃

*calibration: two points automatic calibration

*dimension: 153mm*29mm*16mm

*weight: 52g



Operation:

1* Remove the protective cap

2* First rinse the electrode with distilled water, and suck it with filter paper

3* Turn the meter on by pressing the “ON/OFF” key

4* Immerse the pH meter electrode in the solution to be tested (can not be over the immersion line)

5* Stir gently and wait around 30 seconds till the reading stabilized

6* After finished, clear the electrode with pure water, turn the meter off by pressing the “ON/OFF” key

7* Always replace the protective cap after use


Calibration:

1* Turn on pH meter

2* Immerse the electrode in pH 6.86 standard buffer solution (under the temperature of 25 ℃)

3* After digit stabilized, press the “CAL” button for 5 seconds (the instrument comes into the automatic calibration status) wait until the display digit is 6.86 pH, then complete pH 6.86 point calibration

4* Clean the electrode with distilled water and dry it filter paper, immerse the electrode in pH 4.00 standard buffer solution

5* After digit stabilized, press “CAL” button for 5 seconds, wait until the digit 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 date 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 steps




Attention:

The instrument need re-calibrate in the following condition

Long time no use or use very long time after calibration

The electrode is used very frequently

The testing accuracy requirement is very high

Do not press the “CAL” button long time in the air, otherwise the meter need re-calibrate
