  • Accuracy: 0.01

  • Resolution: 0.01

  • Operating Temperature: 0~60°C

  • Measuring Range: 0.00~14.00

  • Probe Type: Precision glass bulb electrode

How To Use :

  • Remove protective cap.

  • First rinse the electrode with distilled water and suck it with filter paper.

  • Turn the meter on by pressing “ON/OFF” key.

  • Immerse the pH meter electrode in the solution to be tested (should not be over the immersion line).

  • Stir gently and wait around 30 seconds till the reading stabilizes.

  • After finishing, clear the electrode with pure water, turn the meter off by pressing “ON/OFF” key.

  • Always replace the protective cap after use.

Steps :

  • Turn on PH meter

  • Dissolve each buffer solution in 250ML of distilled water

  • Immerse the electrode into the PH 6.86 solution,(under the temperature of 25)

  • Press the “CAL”(calibration)button for 5 seconds and release

  • Display will start flashing 6.86

  • Wait until the display stops flashing.

  • Rinse the electrode with distilled water and dry it with filter paper.

  • Immerse the electrode in PH 4.00 solution,

  • Press “CAL” button for 5 seconds,then press and release immediately second time

  • Reading will start flashing 4.00

  • Wait until display stops flashing

  • Rinse and dry the electrode with distilled water as before.

  • Place the meter back to the buffer solution to test calibration.If incorrect,please repeat the calibration

  • If approximate PH of your test solution is known to be above 0, calibrate the meter using 6.86 and 9.18 solution. To do this, please follow the calibration chart. The third step is the calibration method for 9.18 point.

Note: This item comes  without batteries , and it needs LR44 cell BATTERY

In the following cases, the PH meter needs to be recalibrated:

  • 1. It has been used (or placed) for a long time after calibration.

  • 2. There is inaccuracy.

PH pen calibration method:

  • 1. First take about 250ML of neutral water (preferably distilled water or pure water) (try not to use tap water or mineral water or mountain spring water, otherwise it will affect the data)

  • 2. Mix with calibration powder 6.86, stir evenly to make it fully dissolved.

  • 3. Remove the protective cover of the test pen, turn it on, and immerse the probe in the prepared calibration solution, and check the reading first. If the data is about 6.86 or the deviation is relatively small, no correction is required; if the value deviates from 6.86 relatively large, press and hold the CAL button for three seconds, let go after the screen flashes, and the automatic correction is in progress. It is expected that the display will show END after 5 seconds. The calibration is complete. Take out the ph pen and wash the electrode with distilled or purified water to absorb the liquid.

  • 4. Use the same method for 4.00 calibration powder

  • 5. Generally, only two packs of calibration powder 6.86 and 4.00 are needed, and 9.18 calibration powder is not required

Warning:

  • In order to maintain the stability of the test pen, please do not press the CAL button at will during normal use!

  • This product uses precision glass bubble electrodes with high sensitivity. It is normal that the screen displays 16.00 or the number keeps beating after starting up.
