What is PH meter?
?
PH meter 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.

Calibration
?
1. Immerse the electrode in PH6.86 (under the temperature of 25°C) standard buffer solution of phosphate, and gently shake the electrode.
2. Regulate the trimmer with a screwdriver until the buffer solution value corresponding to the measurement temperature is obtained.
3. Immerse the electrode in ph 4.01 or ph 9.18 the standard buffer solution of borax.
4. After about one minute, until the buffer solution value corresponding to the measurement temperature is obtained. Important: the instrument’s ph range must be re-calibrated
