Introduction: The instrument is suitable for the automatic analysis and detection of permanganate index in surface water, groundwater, drinking water and environmental water. It realizes unattended fully automatic in accordance with the national standard "GB 11892-89 Determination of Water Quality Permanganate Index" Permanganate index monitoring, so as to achieve less work and bring more and more accurate water quality analysis data. Features: Sample transfer system -"True" injection system, non-peristaltic rocker valve hole system. Real-time accurate control of the injection volume, no injection volume data correction settings and back door, effectively guarantee the authenticity and reliability of the data results; -Equipped with a multi-hole sample tray, with no less than 48 bits and no less than 100ml for a single measurement; -High-precision mechanical arm, automatic sample grabbing, multi-channel automatic sampling system, single injection arm can complete the addition of all reagents, simple and reliable structure, lower maintenance cost; -Adaptive electric gripper, self-adaptation of buffing force software, no need for additional air source equipment, no risk of high pressure, no risk of gas leakage, realize silent operation of sample transfer, gripper can automatically judge whether the sample is successfully grabbed, and prevent the measurement process An unexpected situation occurred in the Titration system -Potassium permanganate pump accuracy: 0.2% (5.0ml); sodium oxalate pump accuracy: 0.3% (5.0ml); sulfuric acid pump accuracy: 0.2% (5.0ml); each pipeline of the titration system is individually controlled; the minimum titration volume: 0.03ml; -The terminal titration process adopts the human eye visual simulation judgment, which simulates the human eye's photosensitive response curve, and the titration process records and displays the RGB data of the sensor in real time, non-voltage, current and photometric colorimetric methods; -Adjustable constant temperature titration design, users can set the titration temperature by themselves, when the titration is over-adjustable within the range of 40-100℃, the instrument can automatically deduct the excess part; -The instrument has a "one-key detection" function, no manual duty, in different experimental stages, automatically completes the addition, heating, titration, and automatic analysis of the permanganate index value; -The sample digestion adopts a micro-boiling water bath oxidation design to reduce water evaporation caused by bumping. There is no obvious vapor escape even in an open experimental platform. There is no need to be equipped with an additional fume hood system, a high-power water bath system, and the water bath system can quickly reach stability. The temperature is accurate and constant through PWM closed-loop temperature control technology; -The system is equipped with titration analysis video traceability function, the titration process real-time record shows the color change of the sample reagent in the sample cup, and has the titration video storage and review function. technical parameter: Detection limit: detection limit <0.05mg/L; Precision: RSD<3.0% (glucose standard solution with potassium permanganate value of 3.0mg/L, n=5); Measurement range: Permanganate index (CODMn) measurement range (without dilution, when the sampling volume is 100mL), 0～5.0mg/L; Measurement speed: ≤6 min/sample (continuous measurement); Sample size: 100ml; Titration resolution: 1μL; Number of water bath channels: 9 channels; Constant temperature titration temperature control range: 40-100℃; Constant temperature titration temperature control accuracy: ±0.1℃;
