PURPOSE:To make a temp. correction of a measured value unnecessary without requiring a special measuring instrument by using a composition of ethylene glycol, water, gelling agent and fluorescent dye as a gelling composition and having dynamic viscosity of 50-6,000. CONSTITUTION:The gelling composition composed of a droppable viscous liquid having pasty appearance and 50-6,000 dynamic viscocity (@100 deg.Ccps), and shows a yellowish fluorescent color. If the gelling composition dropped by several drops as a concn. checking agent, said drops become immediately to have the same temp. as that of a diluting liquid. In case the drops are floated by sp.gr difference, an EG concn. of the measuring liquid is at least >=30wt% (in case checking agent for 30% is dropped), and contrarily in case these are sunk, said concn. is less than 30wt%. |
