Optical colorimetry
A. The test tube was washed with the water sample to be tested twice, and then the water sample was added to the calibration line from the test tube to the tube.
B. According to the operation instructions on the back of the colorimetric card, the reagent was added to the test tube in turn.
C. Shake the test tube to dissolve or mix evenly; 
D.After the reaction is complete, the test tube is placed on the edge of the colorimetric card (or white paper), the visual colorimetric effect is better from top to bottom (the monocular colorimetric effect is better), and the color in the tube is the same or similar to the standard color on the colorimetric card.
