Abstract
A device for the control of liquids characterized essentially by the fact that it is made up of a parallelepiped body of transparent material with each other and laterally carrying two series of small tubes colored in increasing intensities and hermetically closed so that to control the composition of a liquid guide For example, the two largest tubes are filled to where they indicate small lines placed on them, then a few drops of reagent are added and the coloration that they acquire compared visually is added. Mind with the color scale of the smaller tubes you can know the characteristics of the liquid to control. (Machine-translation by Google Translate, not legally binding)
