Description:
Name: PH test pen
Material: ABS plastic
Battery specification: 2*LR44 button battery (not included in delivery)
Display mode: digital liquid crystal display
Accuracy: 0.01
Resolution: 0.01
Working temperature: 0~60℃
Measuring range: 0.00~14.00PH
Probe type: precision glass bubble electrode
Applications: tap water, household water purifiers, commercial water purifiers, industrial water treatment, etc.
How to use:
1.Remove the protective cap
2.Rinse the electrode with distilled water first, and then suction with filter paper.
3.Press the "on/off" key to turn on the meter.
4.Immerse the electrode of the pH meter in the solution to be tested (not higher than the immersion line).
5.Shake gently and wait about 30 seconds for the reading to stabilize.
6.After completion, clean the electrode with pure water and press the "on/off" key to turn off the meter.
7.Be sure to replace the protective cap after use.
Pace:
Disinfect each buffer solution with 250ml of distilled water in the pH meter. Immerse the electrode in the pH 6.86 solution (temperature 25 degrees).
Press and hold the "CAL" button for 5 seconds, then release it and the display will start to flash 6.86 Wait until the screen stops flashing.
Rinse the electrode with distilled water and wipe dry with filter paper.
Immerse the electrode in the PH 4.00 solution, press and hold the "CAL" button for 5 seconds, and then immediately press and release the second time the reading will begin to flash 4.00 Wait until the screen stops flashing. Rinse and dry the electrode with distilled water as before.
Put the meter back in the buffer solution to test the calibration. If it is wrong, please recalibrate.
If the approximate pH value of the known test solution is greater than 0, please use the 6.86 and 9.18 solutions to calibrate the meter. To do this, follow the calibration table. The third step is the 9.18 point calibration method.
Note: This model does not have a battery, need to be equipped with LR44 battery
In the following cases, the PH meter needs to be recalibrated:
1. Long-term use (or placement) after calibration.
2. There are inaccuracies.
PH pencil calibration method:
1. First take about 250ML of neutral water (preferably distilled or purified water) (try not to use tap water, mineral water or mountain spring water, otherwise it will affect the data)
2. Mix with 6.86 calibration powder and shake until completely dissolved.
3. Remove the protective cover of the test pen, open the test pen, immerse the probe in the prepared calibration solution, and check the reading first. If the data is around 6.86 or the deviation is relatively small, no correction is required; if the value deviates from the larger 6.86, press and hold the CAL key for three seconds, wait for the display to flash and perform automatic correction before leaving. The screen is expected to end in 5 seconds. The calibration is complete. Take out the ph pencil and wash the electrode with distilled or purified water to absorb the liquid.
4. Use the same method to calibrate powder 4.00
5. Generally, only two packs of 6.86 and 4.00 calibration powders are needed, and 9.18 calibration powders are not required.
Packing list:
1 x 0.01 PH meter high-precision water quality tester, with a 0-14 PH measurement range, suitable for aquariums, swimming pools, indoor and outdoor
3 x calibration powder
1 x instruction manual

Note:
1.In order to maintain the stability of the test pen, please do not press the CAL button at will during normal use!
2.This product uses high-sensitivity precision glass bubble electrodes. It is normal that the display shows 16.00 or the number keeps jumping after power on.
