Titration systemintroduce
1、Precision of potassium permanganate pump:0.2%(5.0ml); Accuracy of Sodium Oxalate Pump:0.3%(5.0ml); Accuracy of sulfuric acid pump:0.2%(5.0ml); Each pipeline of the titration system is controlled separately; Titration minimum volume:0.03ml;
2、The terminal titration process adopts human visual simulation judgment, simulates the human eye photosensitive response curve, and records the titration process in real time to display the sensorRGBData, non voltage, current, and photometric colorimetric methods;
3、Adjustable constant temperature titration design, users can set the titration temperature themselves,40-100When there is an excess of adjustable titration within the temperature range of ℃, the instrument can automatically deduct the excess part;
4、The instrument is equipped withOne click detection "function, without manual supervision, automatically completes liquid addition, heating, titration, and automatic analysis of permanganate index values in different experimental stages;
5、The sample digestion adopts a micro boiling water bath oxidation design to reduce the evaporation of water caused by explosive boiling. Even on an open experimental platform, there is no obvious steam escape, and there is no need to equip an additional fume hood system or high-power water bath system. The water bath system can quickly reach steady state and pass throughPWMClosed loop temperature control technology achieves accurate and constant temperature control;
6、The system is equipped with titration analysis video traceability function, which records and displays the color changes of the sample reagents in the sample cup in real time during the titration process, and has the function of storing and viewing titration videos.
