Abstract
Aparato para la determinación de la cantidad de sebo emitida por una zona de piel de un sujeto vivo, en el que un emisor suministra un flujo luminoso en dirección de un elemento translúcido, previamente aplicado de forma predeterminada contra la zona de piel a estudiar, y en el que un receptor mide el flujo luminoso, transmitido a partir del emisor por transparencia a través del citado elemento translúcido, efectuándose la interpretación de la medida por comparación con la medida obtenida para un estado de referencia de la muestra translúcida, suministrando el emisor de flujo un haz modulado a una frecuencia fija, y estando asociado el receptor de flujo a un circuito para medir solamente el flujo recibido que tiene la frecuencia de modulación del emisor, suministrando una tensión de medida función del citado flujo recibido, caracterizado por el hecho de que la tensión de medida de una determinación es memorizada a voluntad, y enviada a un amplificador diferencial, que la substrae de la tensión de medida de una determinación siguiente, para suministrar la tensión que da lugar a una lectura del valor medido.
