Sentron Argus handheld no glass pH/mV/temp meters
These hand held instruments are digital  pH meters for use with the Sentron range of ISFET probes. The meters feature LCD displays with temperature pH  and help information. The Argus X is completely sealed (IP67) and features inductive recharging and IR data download

The Sentron pH system offers ease of use, portability and a unique non glass probe that can be stored dry and requires no routine maintenance. These robust probes are suitable for just about any application, from laboratory clear liquids to field dirty samples. The probes are very rugged and can be easily cleaned with a toothbrush.

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.
