Abstract
The utility model discloses a water physical and chemical quality quick detecting instrument, comprising a slot suitable for a normal square colorimetric utensil. The inner wall of the slot is longitudinally provided with at least two light emitting diodes of different wavelength. The inner wall of the slot for the square colorimetric utensil corresponding to the light emitting diodes is provided with photo diodes which are one-to-one corresponding to the light emitting diodes. The two inner walls adjacent to the light emitting diodes are respectively provided with another group of at least two light emitting diodes of different wavelength and the photo diodes which are one-to-one corresponding to the light emitting diodes. The slot for the normal square colorimetric utensil is provided with a cover. The working wavelength range of the water physical and chemical quality quick detecting instrument is enlarged because the inner walls of the four sides of the slot for the square colorimetric utensil are all longitudinally provided with the light emitting diodes and the corresponding photo diodes. The application range of the normal square colorimetric utensil is enlarged because the normal square colorimetric utensil is used as a sample cell. The utility model has the advantages of simple structure, low price, convenient carry, and suitability for field experiment.
