Product Description:
PH meter is an instrument used to measure acidity or alkalinity of a solution - also know as pH. pH is the unit of measure that describes the degree of acidity or alkalinity. It is measured on a scale of 0 to 14. There are different scales set by scientific rules to determine this. For instance, if the reading on PH meter is 7 then it is neutral. If it is above 7, then the element is basic and in the case of below 7 then it is acidic. So, this was the measurement criteria or we can say scale for checking the acidity or alkalinity.
Auto Calibrated Features:
In-built calibration with 3 buffer powders(included).Just press a button to finish the calibration. This pH meter is factory
calibrated. Users can use it directly.
Wide Application:
Ideal instrument for any aquarium, the fishing industry, swimming pools, spa, school laboratories, food &
beverage, drinking water etc.
PH CALIBRATION:
1.Immerse the electrode in pH 6.86 (under the temperature of 25ºC)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 ph4.01 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.
