ABSTRACT:
A device for verifying and reading color, particularly used in reading the color of a liquid, the device comprising: a) a guide tube (10); and (b) at least one pair of liquid detection sensors (20), associated to the guide tube (10), the device comprising pairs of spectral-frequency emitting sensors (30, 31, 32) and spectral-frequency receiving sensors (30′, 31′, 32′), associated to the guide tube (10) and oppositely aligned, the spectral-frequency emitting sensors (30, 31, 32) being activated by detection of the liquid by the detection sensors (20). A process of verifying and reading color in liquids by means of a device of verifying and reading color, the process comprising the following steps: (i) calibrating the pairs of spectral-frequency emitting sensors (30, 31, 32) and the spectral-frequency receiving sensors (30′, 31′, 32′); (ii) detecting the liquid by means of the detection sensor (20); (iii) emitting photons at determined frequency ranges of the spectrum by means of the spectral-frequency emitting sensors (30, 31, 32); (iv) receiving the photons by means of the spectral-frequency receiving sensors (30′, 31′, 32′); and (v) reading the frequency received and comparing it with pre-established frequencies.
