Abstract

INSTRUMENTO PORTÁTIL Y MÉTODO PARA LA MEDIDA DE LA CONCENTRACIÓN DE GASES, concretamente, un sensor para la medida de un analito de interés en un medio. En particular, la invención se refiere a un instrumento basados en atenuación de fosforescencia por parte del analito de interés en gases atmosféricos con sistema de compensación de temperatura y de recalibración con un solo punto. Esta invención presenta un diseño más compacto, una mejor disposición en la alineación y reducción de los componentes optoelectrónicos, una mayor eficacia en la recogida y procesado de la información que algunos otros previamente descritos, resultando en un instrumento de medida de alta fiabilidad, portátil y de bajo coste.
