The 'special glass' is silica which contains tiny pieces of metal. pH (KCl) is therefore always more acid than pH (water), although both are neutral at pH 7,0. The meter measures the difference in voltage between the inside and the outside of the glass. This pH solution is designed to help with electrode protection for storage, making it a smart choice for preventative measures. So, if you store their pH sensor in, say, a 1M solution then eventually that will affect the solution in the instrument (because it can leach through the glass) and you will get an incorrect reading.
