Abstract

Dispositivo óptico, portátil y libre de calibración para el registro y monitoreo remoto en línea de la saturación y concentración de oxígeno disuelto en un cuerpo de agua, que opera mediante el procesamiento electrónico de información de datos analógicos obtenidos a partir de la atenuación de la fluorescencia registrada en oscuridad desde un pigmento fluorescente que reacciona con decaimiento de fluorescencia en presencia de oxigeno disuelto cuando ha sido activado por un pulso de luz azul o roja.Optical, portable and calibration-free device for remote online recording and monitoring of the saturation and concentration of dissolved oxygen in a body of water, which operates by electronic processing of analog data obtained from fluorescence attenuation recorded in the dark from a fluorescent pigment that reacts with fluorescence decay in the presence of dissolved oxygen when it has been activated by a pulse of blue or red light.
