Abstract
Improvements in the micro-photocolorimeters, characterized essentially by the fact that they comprise a set of calibrated tubes carrying respectively the liquid type and the problem liquid depending on the latter with an injector device defining the level in the liquid problem, comprising a means of illumination and a variable color filter at will to define the complementary color achieved in the solution, the mentioned tubes being found in relation to a graduation that can be found in them or be external and joint to them.
