Automatic titration detection device

Abstract

The invention discloses an automatic titration detection device which can conduct continuous titration without interruption, and can accurately identify the titration end point. The automatic titration detection device is suitable for automatically titrating and detecting a to-be-detected solution, and comprises a to-be-detected solution storage container, a detecting table unit, a shell, a solution adding titration device, a uniform blending device, a light casting device, a lighting device and an identifying device; the to-be-detected solution storage container is mounted on the detecting table unit; the shell can form a relatively closed detecting space to avoid interruption of stray light; the solution adding titration device is mounted at the top of the shell and located above the liquid face of the to-be-detected solution storage container, and various kinds of reagents needed in the detecting process are added into the to-be-detected solution storage container; the light castingdevice casts light to the to-be-detected solution; the lighting device collects the light intensity array of the to-be-detected solution; and the identifying device is connected with the lighting device and used for identifying the titration end point.

Description

technical field [0001] The invention relates to the technical field of inspection instruments, in particular to an automatic titration detection device. Background technique [0002] In the inspection of sample indicators, most of the detection methods are to carry out a certain pretreatment process on the sample to be tested to obtain the extracted and filtered liquid to be tested, then add the specific indicator to the liquid to be tested, and use the corresponding titrant Carry out manual titration, when the color changes, use human eyes to judge the titration end point, and calculate the target to be measured according to the amount of titrant used. [0003] Due to the difference in judgment of color by human eyes, there will be obvious errors in the judgment of the titration end point during the titration process, which is likely to cause misjudgment and unnecessary disputes; and different experimenters, due to individual differences, may also Different judgments are p...
