Combined type water quality on-line analyzer and using method thereof

The invention discloses a combined type water quality on-line analyzer. The combined type water quality on-line analyzer comprises a supporting plate and an analyzer body, bottom feet are fixed to four corners of the bottom of the analyzer body, a cuvette placing box is arranged on the upper right corner of the top of the analyzer body, and a cuvette protective cover is hinged to the cuvette placing box. The combined type water quality on-line analyzer has the beneficial effects that by arranging a stabilizing mechanism used for increasing placing stability of the analyzer body, the water quality on-line analyzer is picked up and obliquely placed on the supporting plate with a certain angle, firstly, the water quality on-line analyzer abuts against a stable plate, the stable plate is stressed to extrude a spring, the spring extends and retracts, after the oblique side of the analyzer body is placed, the other side of the analyzer body is placed down, and the compressed spring resets, so that the stable plate
