Instrument testing is needed replacing, inspection result is big by interference from human factor；
External light source interference is big, it is necessary to which lucifuge is examined when the 2, examining；
3rd, there is no turbidity checking function, it is also necessary to individually test with transmissometer；
4th, instrument and equipment can not achieve detection many kinds of substance content function at the same time；
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, there is provided a kind of rational in infrastructure, detection is rapid, detection
A kind of hand-held that material can be carried out at the same time Turbidity measurement comprehensively composes Water Test Kits entirely.
The purpose of this utility model takes following technical scheme to realize：
A kind of hand-held composes Water Test Kits entirely, it is characterised in that：Including an all-wave length light source, in the all-wave length light source
It is corresponding in turn in projecting direction and object lens convex lens is installed, as mirror convex lens and full spectrum light electric transducer, the object lens convex lens
And be used to placing cuvette as being provided with a casing between mirror convex lens, in the casing, described sleeve pipe and object lens convex lens and
As straight slot is symmetrically made in the corresponding both sides of mirror convex lens, is pierced by two straight slot for all-wave length light source projects.
Moreover, the all-wave length light source includes a tungsten lamp, the correspondence position below the tungsten lamp light path be provided with one it is anti-
Mirror is penetrated, the light that tungsten lamp projects is deflected 90 ° and is projected in object lens convex lens by the speculum.
Moreover, it is being in that 90 ° of casing side is embedded with a turbidity light source sensor with full spectrum light source projecting direction.
The advantages of the utility model and good effect are：
1st, in this analyzer, original monochromatic source is substituted make it that the detectable material of analyzer is big using all-wave length light source
Big increase, and supporting full spectrum light electric transducer also substitutes original man-to-man sensor, saves corresponding volume so that point
Analyzer easy to miniaturization, can effectively save space, easy to integrate and hold, object lens convex lens and as the supporting correspondence of mirror convex lens is set
Put, all-wave length light source carries out optically focused by object lens convex lens, and the light after converging is projected in cuvette again eventually through as mirror
Convex lens is converged in full spectrum light electric transducer, realizes centralized management and application to light source, ensures the precision of detection.
2nd, in this analyzer, using tungsten lamp as all-wave length light source, the optical wavelength range that it sends is big, and coordinates with it
The monochromatic changes of 200nm~1100nm can be analyzed in full spectrum light electric transducer, this substantially covers common Detection wavelength,
And full spectrum light electric transducer can be changed by analyzing the strong and weak of each wavelength light, so that during a spectral scan, it is right
The light of the detection each wavelength of solution has carried out once absorbing the front and rear contrast of numerical value.
3rd, in this analyzer, diffusing reflection phenomenon can occur for a part of light during all-wave length light source projects, and this portion
Light splitting can be then detected by turbidity photoelectric sensor, so as to complete the detection of turbidity value during one-time detection.
4th, in this analyzer, by all-wave length light source, object lens convex lens, as mirror convex lens, full spectrum light electric transducer and turbid
Degree light source sensor is coordinated, and during all-wave length light source once projects, can complete the inspection of many kinds of substance and turbidity value
Analysis is surveyed, easy to operate, rational in infrastructure, detection is quick, wide adaptation range, meets miniaturization, the Water Test Kits of easy will
Ask.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Embodiment
The embodiment of the utility model is further described below in conjunction with attached drawing；The present embodiment is descriptive, is not
Limited, it is impossible to thus limit the scope of protection of the utility model.
A kind of hand-held composes Water Test Kits entirely, and the innovation of the utility model is, including an all-wave length light source, at this
It is corresponding in turn in all-wave length light source projects direction and object lens convex lens 3 is installed, as mirror convex lens 7 and full spectrum light electric transducer 8, institute
State object lens convex lens and as being provided with a casing 5 between mirror convex lens, be used to place cuvette 9, described sleeve pipe in the casing
With object lens convex lens and as straight slot 6 is symmetrically made in the corresponding both sides of mirror convex lens, is used for all-wave length light source projects in two straight slot
It is pierced by.
In the present embodiment, the all-wave length light source includes a tungsten lamp 1, and the correspondence position below the tungsten lamp light path is provided with
