Description of the drawings
Fig. 1 is the utility model structure diagram；
In attached drawing, parts list represented by the reference numerals is as follows：
1st, microprocessor, 2, display, 3, photosensitive sensor, 4, cylinder, 5, standard solution storehouse, 6, titration slot.
Specific embodiment
The principle and feature of the utility model are described below in conjunction with attached drawing, example is served only for explaining this practicality
It is new, it is not intended to limit the scope of the utility model.
As shown in Figure 1, a kind of full-automatic titrator based on Arduino, including titration slot (6) and positioned at titration slot (6)
Top is for detecting the photosensitive sensor (3) of titration slot (6) interior solution light flux variations, when titration slot (6) interior solution reaches drop
When determining terminal, luminous flux changes, and photosensitive sensor (3) transmits a signal to microprocessor (1), the microprocessor (1)
Control cylinder (4) out of service, the standard solution in standard solution storehouse (5) stops instilling the titration slot (6), while and cylinder
(4) connected stepper motor is out of service, and the rotation step number of stepper motor is scaled the volume of standard solution simultaneously by microprocessor
Result is exported to display (2) and is shown；
Further, the stepper motor is connected with photoelectric code disk, often turns over a circle, and photoelectric code disk sends a signal to micro- place
Device (1) is managed, stepper motor rotates step number and adds one；
Further, the microprocessor (1) uses Arduino development boards；
Further, the display (2) is touch display screen, titrator can be operated in display interface, institute
Stating display interface includes yellow reset button, red start button；
Concrete principle and work step are as follows：The utility model is perceived using photosensitive sensor to be reached by being detected solution
Indicator color change causes the variation of luminous flux to judge titration end-point during titration end-point, and small-sized gas is connected using synchronous motor
Cylinder changes the variation of gas volume in standard solution storehouse to control the addition of standard solution, and by with phase by cylinder
The programmed microprocessor answered contacts the two, when detected solution reaches titration end-point, because detected solution indicator color change
Caused light flux variations, microprocessor control synchronous motor to stop adding in standard solution, and calculate adding for standard solution
Enter amount, display is over the display.Result can be calculated in testing staff accordingly.
1st, it is accurate to pipette in 5 milliliters of tested liquid addition titration cells, indicator is added in, titration cell is put into slot, is put
Enter magnetic stirring apparatus rotor, start magnetic stirring apparatus.
2nd, the reset button of yellow is pressed, resets system program, in state to be detected.
3rd, red start button is pressed, stepper motor starts slowly to rotate with leading screw, and leading screw drives cylinder piston down
Movement by the downward movement of piston, admits air into closed standard solution bunker, in standard solution bunker air pressure increase
Add, make syringe needle of the standard solution in bunker by lower end, slowly instill in the titration cell of lower end.
4th, when reaching titration end-point, indicator color changes, and is changed at this time by titrating the luminous flux of slot, photosensitive
Sensor sends signal after detecting minor variations when light leads to microprocessor, and microprocessor is sent out to stepper motor at this time
Go out signal, stepper motor stops operating and returns to original position, while the step number that microprocessor rotates stepper motor, is converted into addition
The volume of standard solution is shown over the display.
5th, testing staff passes through the addition and the body of fluid to be measured on the concentration of known standard solution, display
Product, you can calculate the concentration of measured matter.
6th, magnetic stirring apparatus is closed, titration cell is taken out with tweezers, new test solution can be added in after liquid is poured out cleaning
Body is detected next time.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
Within new spirit and principle, any modifications, equivalent replacements and improvements are made should be included in the guarantor of the utility model
Within the scope of shield.
