Abstract
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.
Claims15
A system for measuring the concentration of a specific chemical composition of a fluid, said system comprising:
- a light generating device for emitting an excitation light to cause a probe kept in the fluid to emit fluorescent light;
- a fluorescent light receiver having a photoelectric diode for receiving the fluorescent light emitted by the probe and for converting the fluorescent light into an electric current signal;
- and
- a display electrically connected with said photoelectric diode for receiving the electric current signal and for converting the electric current signal into the concentration of the specific chemical composition whereby the concentration of the specific chemical composition is exhibited by said display.
A system for measuring the concentration of a specific chemical composition of a fluid, said system comprising:
- a light generating device for emitting an excitation light to irradiate the fluid such that the specific chemical composition is excited to emit fluorescent light;
- a fluorescent light receiver having a photoelectric diode for receiving the fluorescent light emitted by the specific chemical composition of the fluid whereby the fluorescent light received by said photoelectric diode is converted by said photoelectric diode into an electric current signal;
- and
- a display electrically connected with said photoelectric diode for receiving the electric current signal and for converting the electric current signal into the concentration of the specific chemical composition whereby the concentration of the specific chemical composition is exhibited by said display.
