Introduction: The DR-100A laboratory COD automatic analyzer strictly follows the test methods and reaction conditions specified in HJ-828-2017, adopts advanced automatic control and computer technology, and realizes the laboratory COD batch automatic analysis under the premise of ensuring the accuracy of the data. It can greatly reduce work intensity and improve work efficiency. The analyzer is widely used in environmental monitoring stations at all levels, sewage treatment plants, testing companies, operating companies, scientific research units and other institutions to conduct large-scale COD analysis in laboratories. The analyzer has obtained the national invention patent (patent number: 2014100382881). Features: 1. Batch determination: 25 samples can be determined at one time; 2. The method is based on the national standard (HJ-828-2017), and the indicators are higher than the national standard, reducing human factors, higher accuracy, and better repeatability; 3. Automatically adding reagents: various reagents are automatically added to each digestion tube; 4. Automatic heating and digestion: the thermostatic controller is used to heat and digest all samples synchronously; 5. Automatic flushing: After the digestion is completed and cooled, the condenser tube is automatically flushed with quantitative distilled water; 6. Automatic titration: adopt precise measurement and detection technology, automatically add titrant, and automatically determine the titration end point; 7. Automatic report: After the test is completed, the analysis report will be automatically generated. Technical parameter: Number of samples: 25 Analysis period: 4h Measuring range: (30~700) mg/L (dilutable) Anti-chloride interference: 1000 mg/L Indication error: ±8% Relative Standard Deviation: 2.5% Insulation resistance: >20MΩ Working voltage: AC (220±22)V Rated power: 4000W Temperature: (15~35)℃ Humidity: ≤85%RH
