Abstract

Dispositivo fotométrico (1) para la medición de absorbancia y turbidez en muestras ubicadas en una cubeta (2) a partir de una fuente de luz que comprende una disposición de diodos de emisión de luz (3, 16) ubicados en el interior de una carcasa (13), en el que al menos uno de los diodos de emisión de luz es apto de proporcionar luz ultravioleta, de tal modo que se transmite un haz de luz hacia la cubeta (2) en la cual está la muestra a medir. Este dispositivo permite una medición tanto de la absorción molecular de un cromóforo así como de la dispersión o turbidez de una suspensión.
