Introduction: The fully automatic sulfide acidification and stripping system is specifically designed for pre-treatment of acidification, blowing, and absorption of sulfides in colored or turbid water, soil, and sediment. The instrument adopts an integrated design of vertical acid addition, nitrogen blowing and absorption, and can process 1-6 sets of samples at once. Each unit adopts an independent rotary flowmeter to control the nitrogen flow rate; PID heating temperature control program, automatically heating to the set temperature, automatic alarm for water shortage, and automatic water replenishment; The 7-inch touch screen human-computer interaction system realizes intelligent pretreatment of sulfide determination in water quality. This product is suitable for the pre-treatment of sulfides in surface water, groundwater, domestic sewage, and industrial wastewater of environmental protection, scientific research, hydrology, water conservancy and other units through acidification blowing absorption; Pre treatment of sulfides in soil and sediment through acidification blowing absorption. Features: 1. Integrated design for vertical acid addition, nitrogen blowing and absorption, without the need for lifting brackets; 2. Nitrogen safety constant control, independent control for each unit, without interfering with each other; 3. Intelligent constant temperature water bath, automatic water level control, automatic water replenishment, and automatic water shortage alarm; 4. No need to connect the faucet, no need to connect the drainage channel, low installation requirements; 5. Adopting a 7-inch touch screen human-computer interaction system for convenience and simplicity; 6. Do not occupy the fume hood and save the countertop. Technical parameters: Sample channel: 6 channels; Temperature control: 0-99 ℃, with temperature control accuracy better than ± 1 ℃; Constant temperature heating unit: equipped with automatic temperature control and automatic water level control functions; No need for lifting brackets, the entire device is stable without any risk of air leakage; Nitrogen flow control unit: The host is equipped with a dedicated interface for convenient external nitrogen sources, and the system is equipped with an overvoltage protection system; The nitrogen flow rate of each channel can be independently adjusted, and the flow rate control range should be between 50-500ml/min; Equipped with a nitrogen flow limiting shut-off valve, the nitrogen can be automatically cut off after acidification is completed, saving nitrogen to protect the sample; Acid addition control unit: Vertical acid addition, the acid addition unit is vertically connected to the reaction bottle through a ground mouth; The adjustment knob of the acid adding unit is made of polytetrafluoroethylene material to prevent corrosion by acidic and alkaline liquids; Sample receiving unit: The sample receiving area is equipped with a colorimetric tube snap ring to ensure that the colorimetric tube is stable and securely fixed; The sample receiving unit is designed with built-in hidden pipelines, making operation more convenient; Human computer interaction system: adopts an embedded 7-inch LCD touch screen, which intuitively displays all operating parameters; Two working modes, water bath and non water bath, meet multiple standard requirements simultaneously; Host size (mm): 820 × five hundred and twenty × 350; Rated power: 2000W.
