UPW-C12SCOD national standard reflux digestion device Introduction: The intelligent COD reflux digestion device is developed based on the national standard method HJ828-2017 for the determination of chemical oxygen demand (potassium dichromate method). It adopts a 7-inch intelligent LCD touch screen design, with simple and convenient one click operation, and automatically completes the digestion and cooling process. No need for manual supervision. Single hole heating, fast heating speed, and uniform heating. This digester is widely used for COD determination in industries such as environmental protection, medical care, hygiene, food, tap water, papermaking, pharmaceuticals, sewage treatment, printing and dyeing, petrochemicals, metallurgy, and scientific research institutions. Features: 1. Using 12 graphite dissolution holes that are resistant to high temperature and strong acid and alkali corrosion, the heating is more balanced and the use is safer. 2.12 digestion wells can be individually controlled, and each one can be individually set for heating time and temperature. 3. Adopting a 7-inch color touch screen, the parameters of each channel are displayed intuitively, and the heating temperature and countdown are observed in real time. 4. Adopting a new generation of intelligent temperature controller and precision PID temperature control technology, the temperature control accuracy is high, the heating is rapid, and the digestion temperature is guaranteed. 5. The digestion time can be flexibly set, and after digestion is completed, the instrument automatically stops heating without manual supervision. 6. The condensation method adopts a dual cooling method of air cooling and water cooling, with two high air volume axial fans for heat dissipation, improving efficiency and ensuring condensation effect. 7. The reflux condenser tube has a horn opening, which prevents the addition of reagents from flowing out and facilitates cleaning after digestion. After the sample digestion is completed, the instrument fan can continue to work, assisting in accelerating the cooling of the sample and shortening the overall detection time. The number of opposing spherical condensation bubbles extending from the condenser wall has increased from 2 to 3, greatly enhancing the condensation effect. Technical Specifications: Dissolve quantity: 12 digits Measurement range: 0-1000mg/L (measured after dilution of high concentration water samples) Measurement error: relative standard deviation of standard solution (500mg/L) ≤ 5.0%; The relative standard deviation of industrial organic wastewater (500mg/L) is ≤ 8.0% Display mode: 7-inch LCD touch screen Single hole heating power: 300w Heating temperature: 1-300 ℃ Temperature control accuracy: ± 1 ℃ Set time: 0-9999s Cooling method: water cooling+air cooling Condenser tube: glass burr reflux tube Power supply: AC 220V ± 22V, 50HZ
