You can measure the pH of a solution using pH paper or a pH meter.
nothing
pH is not a measure of how strong an acid is. pH is a measure of the concentration of hydronium ions in a solution, which is dependent on both the strength of the acid or base and its concentration in a given solution.
pH level is a short term for "Potential Hydrogen" The pH of any solution is the measure of its hydrogen-ion concentration. The higher the pH reading, the more alkaline and oxygen rich the fluid is. The lower the pH reading, the more acidic and oxygen deprived the fluid is.
It measures acidity or alkalinity.

The pH is a measure of the acidity/alkalinity of a solution.
A measure of the acidity of the solution
pH is a measure of the hydrogen ion (H+) activity in a solution.
The pH is a measure of the acidity/basicity of a solution.
pH is a measure of acidity or alkalinity of a solution.
pH paper and pH meter
pH is a measure of the acidity or basicity of a solution. The pH of a solution is temperature-dependent.pH is a measure of how acidic or alkaline (the opposite of acidic) a material is. It has nothing to do with temperature.
The pH is a measure of the activity of the ion H+ in a solution.
hey
pH is a measure of the acidity of the solution. It describes the concentration of H+ or H3O+ ions in a solution. pH= -log10[H+]. Therefore, the lower the pH, the higher the concentration of hydrogen atoms and the more acidic the solution.
The measure of the H+ concentration is the pH.
If you think to pH, measure this value with pH paper or with a pH-meter.
