System for measuring concentration of chemical composition of fluid

摘要

A system is designed to measure the concentration of a specific chemical composition of a fluid and is formed of a light generating device, a fluorescent light receiver, and a display. The light generating device emits an excitation light to cause a probe submerged in the fluid to emit fluorescent light, which is received by a photoelectric diode of the fluorescent light receiver and is than converted by the photoelectric diode into an electric current signal. The display receives the electric current signal, which is then converted by the display into the concentration of the specific chemical composition of the fluid. The information on the concentration of the specific chemical composition is exhibited on the display.
