Abstract
The utility model provides a color comparator which consists of a case, an electronic detection circuit and a container, wherein the container is used for containing detected samples; and the electronic detection circuit comprises a power supply, a light source, a color sensor, a computer processor and a data display. The color comparator can be used for measuring the water quality without manual color comparison judgment or advance drawing of an absorbency-density curve, so the measuring accuracy and the efficiency are high. In addition, the utility model has the advantages of small structure, portability and convenient field use.
Description
Technical field
The utility model relates to surveying instrument, is specifically related to the tintmeter that water quality monitoring is used.
Background technology
In water quality monitoring and analyzing, there are many test events to adopt colorimetric analysis to carry out, therefore relevant professional surveying instrument is widely used in the water quality monitoring and analytical control work of different scales water factory, hospital, environmental administration, health and epidemic prevention station and industrial and mining enterprises.At present, the instrument that adopts colorimetric analysis to carry out the water quality monitoring analysis has two kinds, and a kind of is relatively instrument of visual method color chips, and another kind is the higher spectrophotometer of precision.
The ultimate principle and the using method of visual method color chips comparison instrument are: the color of the color chips of the color of the chromophoric solution of tested sample and standard is compared, with artificial visually examine's method, estimate the constituent content of tested sample.Though visual method color chips relatively apparatus structure is small and exquisite, use simple, shortcoming also clearly, promptly precision too low (general permissible error is between 20% to 40%) therefore is difficult to satisfy high-quality water quality monitoring requirement.
Spectrophotometric measuring accuracy is higher, but equipment volume is bigger, and manufacturing cost is very high, and open-air use inconvenience generally is placed on the laboratory and uses; In addition, use the spectrophotometer test, " absorbance---the concentration curve " that must measure the absorbance or the transmitance of the setting wavelength of standard model by artificial drafting in advance, so efficiency of measurement is not high.
The utility model content
The purpose of this utility model provides a kind of easy to carry, simple to operate, detection speed is fast and precision is higher water quality measurement instrument.
To achieve these goals, the technical scheme taked of the utility model is:
A kind of tintmeter comprises housing, electronic detection circuit and holds the container of tested sample that it is characterized in that: described electronic detection circuit comprises power supply, light source, color sensor, computer processor, data display equipment; The described container that holds tested sample is a transparent glass vessels; Described light source irradiation direction is aimed at container and the color sensor that holds tested sample, and the container that wherein holds tested sample is positioned at the centre of light source and color sensor; Color sensor is connected with computer processor, data display equipment; Store the standard colour tone and the brightness data of different elements in the internal storage of described computer processor.
By optical principle as can be known, the color difference that different material presents, the content of same substance is high more, and then color is dark more.The utility model is with the hue and luminance value of tested element, compare computing with the standard colors tone pitch and the brightness value of the different elements of having stored in the instrument internal storage, thereby determine exactly that tested element is what and what of content, promptly reached the purpose of colorimetric measurement.The utility model need not rely on manually " colorimetric judgement " or draw in advance " absorbance---concentration curve ", so measuring accuracy and efficient are higher; The utility model structure is small and exquisite in addition, is easy to carry and open-air the use.
Description of drawings
Fig. 1 is the theory diagram of the utility model tintmeter.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, the utility model comprises power supply 1, light source 2, holds cuvette 3, color sensor 4, CPU processor 5, the LCDs 7 of tested sample; Wherein, power supply 1 is a lithium battery, and is furnished with charger 8; Use the LED light emitting diode as light source 2; Color sensor 4 is the TCS230 color sensor that U.S. TAOS company produces; CPU processor 5 is the INTEL8051 single-chip microcomputer; The standard colour tone and the brightness data that have different elements in the data-carrier store of CPU processor 5 inside; CPU processor 5 is provided with associative operation button 6.
Content with ferro element in the measurement water is example, and the utility model using method and principle of work are as follows:
At first select the typical curve of ferro element by the operation knob, show on the liquid crystal display " iron ", press the measurement button then, the light that light source sends sees through cuvette, the color transmission is on color sensor, according to the data of color sensor transmission, by single-chip microcomputer read, comparison, computing, and net result (the corresponding concentration numerical value of " iron " element) is presented on the LCDs.
The utility model tintmeter can be used for measuring the content of chlorine residue in the water, iron, manganese, ammonia nitrogen, nitrite, the pH value and the colourity of water.
