6200 series pH/mV/Ion/Temp meters
These hand held instruments are completely self contained high resolution pH meters. This page describes two models. The standard 6230 meter has 0.01 pH resolution The high resolution 6250 series has 0.001 pH resolution and includes ion measurement and can be used with a wide range of ISE (Ion Selective Electrodes )

The Kit configuration includes everything you need to make pH measurements

Ph is a measure of the degree of the acidity or the alkalinity of a solution as measured on a scale of 0 to 14. The midpoint of 7.0 on the pH scale represents neutrality. A "neutral" solution is neither acid nor alkaline. pH below 7.0 indicate acidity; pH above 7.0 indicate alkalinity. pH indicates the intensity of alkalinity or acidity in the same way temperature tells how hot something is but not how much heat the substance carries. More specifically, pH is the negative of the logarithm of the hydrogen ion concentration of a solution. The hydrogen ion concentration is the weight of hydrogen ions, in grams, per liter of solution. In neutral water, for example, the hydrogen ion concentration is 10E-7 grams per liter; the pH is therefore 7. Since it is hydrogen that is responsible for acidity and alkalinity, the abbreviation "pH" stands for "potential of hydrogen." The neutral point of 7.0 actually indicates the presence of equal concentrations of free hydrogen and hydroxide ions.
