Introduction: The DH4000Pro food sulfur dioxide detector strictly follows standard requirements, integrating heating, distillation reflux, cooling, nitrogen blowing control, magnetic stirring, and receiving work. It can provide processing of 1-4/6 samples simultaneously, greatly improving the accuracy of detection data and reducing working time. Features: 1. It can simultaneously complete heating, distillation reflux, cooling, nitrogen blowing control, magnetic stirring, reception and other tasks; 2. External high-power chiller for cooling, with good cooling effect and convenient maintenance in the later stage; 3. Adopting far-infrared ceramic heating, energy-saving and environmentally friendly, with good waterproof effect and resistance to acid and alkali corrosion; 4. 1-4/6 sets of samples can be made at once, and each channel can be independently controlled; 5. Programmable control, power and time can be freely set; Compared to the regular model, the Pro model has added an automatic acid adding function, with an acid adding volume of 0-20ml and an accuracy better than 2%; Optional receiving bottle tray weighing function, with an accuracy better than ± 1g. Applicable standards 7. GB5009.34-2022 "National Food Safety Standard - Determination of Sulfur Dioxide in Food" 8. Part 4 of the Chinese Pharmacopoeia - Determination of residual sulfur dioxide content 9. Use a color recognition system that simulates human eyes to determine the titration endpoint; The built-in calculation formula directly calculates the detection results and can generate a detection report with just one click. Technical parameters: Model: DH4000 Sample channel: 4 channels Control mode: Independent control for each channel Heating method: far-infrared ceramic radiation heating Distillation flask: standard 1000ml two necked flask Power control: PID power control, single channel 0-500W adjustable Time control: single channel 0-600min can be set Nitrogen flow rate: flow rate range 200-2000ml/min, or 50-500 Nitrogen control: An independent rotary flowmeter is used to control the nitrogen flow rate, and overpressure can automatically relieve pressure Mixing method: The bottom of the receiving bottle is equipped with a magnetic stirrer, and the mixing speed can be monotonous for a single group, with infinite speed regulation Automatic weighing: optional Cooling system: high-power chiller, ensuring continuous cooling Host size: 960x500x320mm Rated power: 2000W Rated voltage: 220V/50HZ
