What is Alkaline Meter ?

Alkaline meter is an electronic device used for measuring the PH value (acidity or alkalinity) of a liquid. 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.

Compared with similar products from other suppliers, our alkaline meter has the function of automatic temperature compensation function, which obviously improves the accuracy of measurement (especially when the temperature difference between liquid and space is large). With automatic temperature compensation, the meter has "ATC" mark. This PH meter is packaged with 2 packs of calibration powder, screwdriver and plastic box.

Alkaline Meter Calibration Method :

1. Firstly, 6.86 calibration powder is poured into 250ml distilled water or pure water and stirred well. Then turn on the PH meter and put the electrode into the calibration solution.

2. See if the PH meter shows 6.86 or 6.8 in the correction solution of 6.86. If it does not show 6.86 or 6.8, adjust the screw in the screw hole (at the back of the PH meter) with a screwdriver and set the value to 6.86 or 6.8 (0.01 or 0.1 resolution)

3. Find a new cup, fill the same 250 ml of pure water or distilled water. Pour the correction powder of 4.01 into it, mix it well, and put the PH meter which is calibrated just now into the correction solution of 4.01.

4. If 4.01 or 4.0 is displayed,it indicates that the correction is successful, if the display is not 4.01 or 4.0, it needs to be revised in the same way as before.
