    • The invention concerns a device and a method for controlling the protective temperature and alkalinity reserve of a cooling liquid, obtained by diluting an anti-freeze compound containing carboxylic compounds. The device comprises at least a refractometer, pH paper and a test tube in a portable closed chamber. The invention is characterised in that the test tube is graduated in protective temperature, each division corresponding to a volume X of cooling liquid having a known protective temperature varying with the dilution rate C of said anti-freeze compound in the water, and a minimal required alkalinity reserve, X corresponding to (10 x VA)/(RA x C), VA being the volume of acid, RA the alkalinity reserve and C the anti-freeze compound concentration in the cooling liquid, expressed in percentage.
    • 本发明涉及通过稀释含有羧化合物的防冻化合物而获得的用于控制冷却液的保护温度和碱度储备的装置和方法。 该装置在便携式封闭室中至少包括折射计,pH纸和试管。 本发明的特征在于,试管在保护温度下分级,每一部分对应于具有与所述防冻化合物在水中的稀释速率C变化的已知保护温度的冷却液体积X. 碱度储备,对应于(10×VA)/(RA×C)的X,VA为酸的体积,RA为碱性储备,C为冷却液中的防冻化合物浓度,以百分比表示。
