How to Select a pH or ORP Meter
pH is a measure of the acidity or alkalinity of a solution, numerically equal to 7 for neutral solutions, increasing with increasing alkalinity and decreasing with increasing acidity. The pH scale commonly in use ranges from 0 to 14. ORP (oxidation reduction potential) is a method of measuring the degree of completion of a chemical reaction by detecting the ratio…
How Earth Resistance is Measured
The term “earth resistivity” expressed in ohm-centimeters (abbreviated ohm-cm) is one basic variable affecting resistance to earth of an electrode system. But the actual value of earth resistivity need not be measured to check the electrode earth resistance. Consider other fields where the value of resistivity is measured; also some of the factors affecting it that are of interest in…
