Abstract: La invencion se refiere a un metodo para analizar la condicion en que se encuentra un fluido funcional que comprende: (1) obtencion de una muestra del fluido usado; (2) colocacion de la muestra de fluido sobre un medio de ensayo; (3) reaccion del fluido con un indicador en el medio de ensayo; (4) analisis visual de los resultados de la reaccion resultante en la determinacion de la condicion en que esta el fluido. Se describe ademas un dispositivo para analizar fluidos funcionales en la forma de un medio de ensayo consistente en un material absorbente o no absorbente que ha sido tratado con un indicador quimico, substancia marcadora o un reactivo revelador o detector sobre el que se coloca una muestra del fluido a ensayar. Los componentes del medio de ensayo tratado reaccionan con los componentes del fluido de ensayo proporcionando una indicacion visual, por ejemplo un cambio de color, para juzgar la condicion, la presencia de una substancia marcadora u otro parametro del fluido. El fluido funcional puede ser un lubricante, combustible u otro fluido funcional de innumerables fuentes, que incluyen motores de combustion interna, turbinas, transmisiones, diferenciales, bombas, operaciones de trabajado de metales, sistemas de enfriamiento, etc. y puede ser disolvente organico o disolvente acuoso.

Abstract: The invention relates to a method to analyze the condition of a functional fluid comprising: (1) obtaining a sample of the used fluid; (2) placing the sample of the fluid to a test medium; (3) reacting the fluid with an indicator in the test medium; (4) analyzing visually the results of the reactor resulting in the determination of the condition of the fluid. Further an apparatus for analyzing functional fluids is disclosed in the form of a test medium consisting of an absorbent or nonabsorbent material which has been treated with a chemical indicator, marker substance or a developer or detector reagent upon which a sample of the fluid to be tested is placed. The components in the treated test medium react with components in the test fluid providing a visual indication, for example a color change, to judge the condition, the presence of a marker substance or another parameter of the fluid. The functional fluid may be a lubricant, fuel or other functional fluid of innumerable sources, including internal combustion engines, turbines, transmissions, differentials, pumps, metalworking operations, cooling systems, etc, and be either organic solvent or aqueous based.
