Liquid colorimetric device and method

Abstract

The invention discloses a liquid colorimetric device and a method. In the device, one or more perspective surfaces for observing liquid are arranged in a container; a colorimetric card is arranged at the bottom, the side wall of the container or in the liquid so as to be observed through the liquid; multiple marks are arranged on the colorimetric card; one mark is the same as the corresponding color of the multiple colors in lightish liquid and rich-colored liquid. The method adopts the liquid colorimetric device to perform liquid colorimetry, and comprises the steps as follows: firstly, the colorimetric card is arranged at the bottom, the side wall of the container or in the liquid; secondly, the mark on the colorimetric card is read, to be specifically, when the color of the liquid is deeper than that of the mark, the mark is invisible, and among the marks with colors arranged from light to rich, the first visible mark near to the end of the marks with lighter colors is the color value of the color of the corresponding liquid. According to the liquid colorimetric device and the method, provided by the invention, as the device is perspective, and according to the principle that a richer color can conceal a lighter color at the same hue, through the liquid, urine for instance, the colorimetric card can be observed, and the color of the liquid is measured quickly and accurately through utilizing the appearance and disappearance of the marks on the colorimetric card.

Description

technical field [0001] The invention relates to a device and method for accurately measuring liquid color, in particular to a liquid colorimetric device and method. Background technique [0002] The normal fresh urine of healthy people is generally slightly yellow. Except for diseases, the color of urine is directly related to the amount of drinking water. The main factor for the darkening of urine is drinking less water. The survey shows that nearly one-third of adults and two-thirds of children in my country do not drink enough water. The Chinese Nutrition Society recommends that the human body needs to drink 1500ml to 1700ml of water per day, but the amount of drinking water for each person must be considered in combination with their own physiological conditions and seasonal factors. Usually there is no fixed value, such as hot weather, should drink more after exercise Water, or the dry climate in autumn should also consciously increase the amount of drinking water, whi...
