The utility model discloses a portable online full gloss register for easy reference water quality monitoring system structure, standard liquid appearance input is connected with standard liquid appearance storage chamber with standard liquid appearance transmission union coupling, standard liquid appearance transmission pipe, the liquid appearance input that awaits measuring links to each other with the liquid appearance transmission pipe that awaits measuring, and the liquid appearance of awaiting measuring transmission pipe is connected with the liquid appearance storage chamber that awaitsmeasuring, the pulse xenon lamp light source arouses the full gloss to set to music under the transmission behind the full gloss register for easy reference light path passageway separated time lens,through transmission spectrum route selector and transmission spectrum focusing lens focus, projects the spectrum photosensitive element by the spectrum reflector again, saves at data storage component ROM behind spectrum photosensitive element discriminating digit spectral information, the problem of prior art monitoring process complicated, the precision is also unable unified, can not carry out real -time multi -parameter simultaneous determination and visual etc is solved.

The invention discloses a portable on-line full spectrum water quality monitor. A standard liquid sample input end is connected with a standard liquid sample transmission pipe; the standard liquid sample transmission pipe is connected with a standard liquid sample storage room; a to-be-tested liquid sample input end is connected with a to-be-tested liquid sample transmission pipe; the to-be-testedliquid sample transmission pipe is connected with a to-be-tested liquid sample storage room; xenon flash lamp light source stimulates full spectrum to be transmitted through a full spectrum light path channel branching lens, then the full spectrum is focused through a transmitted spectrum channel selector and a transmitted spectrum focusing lens, is projected to a spectrum photosensitive elementthrough a spectrum reflector, and then the spectrum photosensitive element identifies digital spectrum information and then stores the information to a data memory element ROM. The portable on-line full spectrum water quality monitor solves the problems that a monitoring process is complex, precision cannot be uniform and real-time multi-parameter simultaneous determination and visualization cannot be performed in the prior art.
