Principle and select quick measuring card 35 or container 37 to be tested.In the present embodiment, by taking pesticide residue and formaldehyde test as an example respectively
It illustrates.
Detecting Pesticide is typically to be hydrolyzed to acetic acid and indophenols (indigo plant according to cholinesterase catalysis indophenols acetic acid esters (red)
Color), and organophosphor or carbamate have inhibiting effect to cholinesterase, can make the process hair of catalysis, hydrolysis, discoloration
It is raw to change what this principle carried out.Therefore, the quick measuring card 35 can be selected high to organophosphor and carbamate sensitive
Cholinesterase and the test paper made of color developing agent.When test, first open detection instrument makes the heating devices heat of detector to predetermined
Temperature (such as 37 DEG C).Then vegetable sample is chosen, its surface soil is wiped, 1cm or so square fragments is then cut into, takes about 5g
(reference value) is put into bottle with cap, and 10ml (reference value) pure water or buffer solution is then added, shakes 50 times (reference values), is stood
2min (reference value) or more, then takes a piece of quick measuring card 35, tears protective film off, the white by few drops of sample drop in quick measuring card 35
On tablet reaction zone, quick measuring card 359 is positioned on quick measuring card bearing 36 thereafter, the positioning of quick measuring card bearing 36 is positioned over described
In shrinkage pool 211, and lid 1 is covered, makes quick measuring card 35 at a certain temperature fully and example reaction.Quick measuring card 35 is in detector
After the placement predetermined time (about 10 minutes), after stable reaction, the color detection module 31 of the detection device can be to reaction
Rear quick measuring card 35 carries out color detection, and control module 7 by analysis and operation, goes out to control 5 real-time display of display device

It is aoxidized to form blue-green compound by ferric ion in property solution, shade is directly proportional to content of formaldehyde.When test, first open
Detector makes the heating devices heat of detector to predetermined temperature (such as 20 DEG C or more).Then by the phenol reagent (configuration of phenol reagent
Can refer to known technology, when manufacture packages and is put into togerther in packing box with the intelligent detecting instrument of the present invention) be put into it is described
In container 37, container 37 is placed in the shrinkage pool 211, opens lid 1, so that air is contacted with phenol reagent and occurs anti-
It answers.After color stability (being usually after 15 minutes), lid 1 is covered, makes the color detection module 31 of detection device to reaction
The color of solution afterwards is detected.After detection device detects color, control module 7 is by analysis and operation, to controllable
5 real-time display of display device processed goes out testing result, and testing result can be wirelessly transmitted to other intelligence by bluetooth module
Terminal, such as PC terminals or portable mobile termianl.
Test for sundry item, according to the difference of its testing principle, by selecting different quick measuring card 35 or reagent
Solution can similarly be completed to detect.The intelligent detecting instrument of the present invention is mainly by the color after detection reaction automatically, to automatic
Detect the concentration results of sample, without the color after artificial contrast's reaction, thus its error rate is lower, using it is more convenient just
It is prompt.In addition, the intelligent detecting instrument of the present invention is applicable to all kinds of projects that can be tested by chromogenic reaction principle, not only
It can be used for testing concentration of formaldehyde and pesticide residue degree, it may also be used for test benzene concentration, PH acid-base values, hydrogen peroxide concentration, nitrous acid
Salinity etc..
Although being disclosed to the present invention by above example, the scope of the invention is not limited to this,
Under conditions of present inventive concept, above each component can with technical field personnel understand similar or equivalent element come
It replaces.
