Abstract
The utility model discloses a multi-parameter colorimetric device. The multi-parameter colorimetric device comprises a round colorimetric pond, wherein light sources, optical filters, unthreaded holes, second lenses, first lenses and detectors are sequentially arranged in two mutually perpendicular directions of the colorimetric pond; the light sources are LED light sources; transmitting end fixing plugs are arranged between the light sources and the unthreaded holes; receiving end fixing plugs are arranged between the first lenses and the detectors; and the optical filters are narrow-band optical filters. The utility model has the advantages that different adapters can be configured to change the diameter of the colorimetric pond, so as to meet the measurement requirements of different parameters; different light sources and optical filters work together to achieve multi-parameter measurement; and the multi-parameter colorimetric device has a simple structure, can achieve multi-parameter measurement, can be used extensively, and solves the problem that a conventional instrument can only measure a single parameter or has less experimental parameters.
Description
Technical field
The utility model relates to a kind of colourimetry device, especially relates to the multiparameter colorimetric device in a kind of colourimetry instrument.
Background technology
At present, in the colourimetry instrument, generally be to survey one-parameter or spectrophotometer.The project that one-parameter is surveyed can not satisfy the measurement of routine work very little; Spectrophotometer is too complicated, and the cost height has movable member, is out of order easily.Therefore, existing colourimetry instrument exist parameter for a long time cost with regard to high, operation is very complicated, a series of problems such as movable member is out of order are easily arranged.
The utility model content
The utility model has overcome shortcoming of the prior art, and a kind of multiparameter colorimetric device is provided.
The technical solution of the utility model is: a kind of multiparameter colorimetric device, comprise colorimetric pool, described colorimetric pool is circular, all is disposed with light source, optical filter, unthreaded hole, second lens, first lens, detecting device on two orthogonal directions of described colorimetric pool.
Described light source is a led light source.Between light source and unthreaded hole, be provided with the fixing plug of transmitting terminal, between first lens and detecting device, be provided with the fixing plug of receiving end.Described optical filter is a narrow band pass filter.
Compared with prior art, the utility model has the advantages that: by disposing different adapters, can change the diameter of colorimetric pool, to satisfy the measurement requirement of different parameters; Cooperation by different light source and optical filter can realize the measurement of multiparameter; Simple in structure, can realize measuring multiple parameters, of many uses, solve existing instrument and can only survey one-parameter or the few problem of experiment parameter.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is a structural representation of the present utility model.
Embodiment
A kind of multiparameter colorimetric device, as shown in Figure 1, comprise: light source 1, the fixing plug 2 of transmitting terminal, optical filter 3, unthreaded hole 4, second lens 5, colorimetric pool 9, first lens 6, the fixing plug 7 of receiving end, detecting device 8, wherein: colorimetric pool 9 is circular, can dispose different adapter 10, on two orthogonal directions of colorimetric pool 9, all be disposed with detecting device 8, the fixing plug of receiving end 7, first lens 6, second lens 5, unthreaded hole 4, optical filter 3, the fixing plug 2 of transmitting terminal and light source 1 etc., described light source 1 is a led light source, and described optical filter 3 is a narrow band pass filter.The effect of first lens 6 is that light is converged on the detecting device 8 better.
Principle of work of the present utility model is: after the light that light source 1 sends carries out filtering by optical filter 3, obtain necessary wavelength, remove unnecessary parasitic light by unthreaded hole 4 then, be radiated on second lens 5, by colorimetric pool 9 parallel light is incident on first lens 6 at last, at last illumination on detecting device 8, can obtain the absorbance size by the shade of solution in the colorimetric pool 9.The light of vertical direction also is same principle.Luminous by two-way, two-way receives, make light can realize the measurement of multiple parameter, simultaneously can also carry out the measurement of another purposes, by changing light source, make the light that sends infrared, of the measurement of the detecting device of colorimetric pool 90 degree directions as scattered light, the light of 180 degree directions is as the measurement of transmitted light, thus the measurement of realization turbidity.Can also realize the measurement of the absorbance of specific wavelength.
Claims (4)
