PH METER
Product Code : KA+LE211
Brand Name : KAPLAS SCIENTIFIC
Product Description

KA+LE 211 PH METER  is a measure of how acidic or alkaline a solution is. In pure water at room temperature, a small fraction (about two out of every billion) of the water molecules (H 2 O, or really, H-O-H) splits, or dissociates , spontaneously, into one positively charged hydrogen ion (H + ) and one negatively charged hydroxide ion (OH - ) each. There is an equal number of each ion, so the water is said to be "neutral".

Some materials, when dissolved in water, will produce an excess of (H + ), either because they contain these ions and release them when they dissolve, or because they react with the water and cause it to produce the extra hydrogen ions. Substances which do this are called acids . Likewise, some chemicals, called bases or alkalis , produce an excess of hydroxide ions.

A strong acid, like hydrochloric acid, HCl, releases essentially all of its H + in water. The concentration of H + is the same as the total concentration of the acid. A weak acid, like acetic acid (the acid in vinegar), may release only a few percent of the hydrogen that it has available.

Most useful for PH and redox potential measurements, supplied with slop correction facility.
