Description
Technical field
The utility model belongs to chemical analysis instrument field, is specifically related to a kind of titrator, particularly the novel titrator of one.
Background technology
Analysis by titration is the ripe conventional method of analysis of industry, agricultural, environment, medicine and other fields widespread use, and this way endpoint is the change based on color or turbidity, mainly for a long time relies on manual completing, and workload greatly and easily introduce personal error.Photometric titration is the change by photometer recording solution absorbance in titration process, thus obtains titration end-point.This way is not subject to the impact of operator's difference, can be used for conventional titration analysis, can be used for naked eyes yet and be difficult to the dark system changed that distinguishes between colors.At present, the device for photometric titration analysis converts primarily of spectrophotometer or luminosity probe.The former not easily realizes robotization, and operation is more loaded down with trivial details; The latter generally adopts integrated structure, and light source, photovoltaic converter are in opposing seal or semiclosed system, need lucifuge to operate, and not easy cleaning.What is more important, these two kinds of photometric titrators all cannot realize, synchronously respond to the change of volumetric soiutions color, and there is the shortcoming of response lag, these all limit promoting the use of of photometric titration.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provides a kind of Real-Time Monitoring, easy to operate novel titrator.
The purpose of this utility model is achieved in that a kind of novel titrator, it comprises magnetic stirring apparatus, described magnetic stirring apparatus is provided with beaker, in described beaker, leftward position is provided with titration apparatus, described titration apparatus comprises flexible pipe, described flexible pipe upper end is connected with buret by solenoid valve, in described beaker, right positions is provided with open luminosity sensor, described open luminosity sensor comprises luminosity probe, patch light-emitting diode and photodiode, described patch light-emitting diode is arranged on beaker bottom right positions, described solenoid valve and luminosity probe are connected with main control system by wire.
Described patch light-emitting diode and luminosity probe are located along the same line.
Control circuit, display screen and keyboard is integrated with in described main control system.
Described buret is provided with scale.
The green adopting surface mounted LED of wavelength 525nm centered by described patch light-emitting diode.
It is adjustable that described luminosity probe immerses solution height.
The beneficial effects of the utility model: the utility model adopts open luminosity sensor to detect, there is not closed dead angle in open by design, can the change of sync response solution colour, luminosity probe immersion solution height is adjustable simultaneously, light path is variable, sensitivity can need with mensuration system and change, Real-Time Monitoring, and monitoring simultaneously precisely; Patch light-emitting diode adopts the green adopting surface mounted LED of centre wavelength 525nm, can working sample terminal solution colour by colourless become redness time more obvious, realize the use of open luminosity sensor under bright environment, without the need to adopting black out device, total the utility model have compact, easy to operate, without the need to the advantage of black out, Real-Time Monitoring.
