Abstract
The utility model provides a chemical titration end point judgment instrument for fertilizer check, and belongs to the technical field of the fertilizer check. A metering electromagnetic valve is arranged on a titration pipe; a cross mark line groove is formed in the middle of a base; a T-shaped arc groove is formed in the base; an illumination lamp is arranged on the base above the T-shaped arc groove; a T-shaped convex block is arranged at the bottom of a lamp base of the illumination lamp, positioned in the T-shaped arc groove and glidingly connected with the base; a colorimeter and a controller are arranged on one side of the base, opposite to the illumination lamp; the colorimeter is connected with the controller; the controller is connected with the metering electromagnetic valve on the titration pipe; a single-disc shaker is arranged above the cross mark line groove of the base; an anti-slip cushion is arranged on the single-disc shaker; a titration triangular flask is arranged on the anti-slip cushion. According to the chemical titration end point judgment instrument, the phenomenon of inaccurate check data resulted by the end point judgment error caused by the titration end point error can be avoided.
Description
Technical field
The utility model relates to fertilizer inspection technology field, specifically a kind of fertilizer check chemistry titration end point judging instrument.
Background technology
General, in fertilizer chemical analysis, often can adopt chemical titration to measure for certain hydrolysis ion.In titrimetry, in the time being titrated to equivalent point, often can, for judgement, often determine and stop titration by means of the change color of indicator without any appearance, now the color transition point of indicator, is titration end-point.The control of titration end-point is that the depth of terminal colour will directly affect the accuracy of assay.In fertilizer check chemistry, the chloride ion content method of inspection is the back titration in volumetry, terminal is shallow orange red or shallow brick-red for occurring, the more difficult control of naked eyes, often cause inconsistent the produced end point error of titration end-point and equivalent point, cause the misjudgment of terminal and cause check data inaccurate.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of fertilizer check chemistry titration end point judging instrument is provided.
The technical solution of the utility model realizes in the following manner, this fertilizer check chemistry titration end point judging instrument, and its structure comprises buret, base, color difference meter and controller, is provided with metering solenoid valve on buret; Base middle part is provided with right-angled intersection marking wire casing, offers T-shaped arc groove on base, and T-shaped arc groove is offered as the center of circle take the point of crossing of right-angled intersection marking wire casing; On the base of T-shaped arc groove top, be provided with illuminating lamp, the lamp socket bottom of illuminating lamp is provided with T-shaped projection, and T-shaped projection is arranged in T-shaped arc groove and is connected with base sliding; A side relative with illuminating lamp on base is provided with color difference meter and controller, and color difference meter connects controller, and controller is connected with the metering solenoid valve on buret; The right-angled intersection marking wire casing top of base is provided with single-deck shaking table, on single-deck shaking table, is provided with slipmat, is provided with titration triangular flask in slipmat.
On controller, be provided with metering display screen.
Illuminating lamp is connected with controller by wire.
Buret is fixedly connected with base by support.
The beneficial effect that the utility model compared with prior art produced is:
This fertilizer check chemistry titration end point judging instrument can open or close illuminating lamp before use as required, open single-deck shaking table and shake titration triangular flask, open color difference meter and controller simultaneously, open metering solenoid valve and start titration, the colour of the solution colour in color difference meter detects titration triangular flask is closed metering solenoid valve by controller after changing, note down and show that flow, titration complete is titration end-point.
This fertilizer check chemistry titration end point judging instrument can be avoided the insensitive phenomenon of visual inspection to change color, avoids producing titration end-point error, causes the misjudgment of terminal and causes the inaccurate phenomenon of check data.
This fertilizer check chemistry titration end point judging instrument is reasonable in design, simple in structure, safe and reliable, easy to use, be easy to safeguard, has good value for applications.
