KN-COD60COD High Chloride Reflux Automatic Digestion Instrument Introduction: Guided by the industry standard "HJ_T 70-2001 Determination of Chemical Oxygen Demand in High Chloride Wastewater - Chlorine Correction Method", and taking into account the actual needs of users, our company has developed the KN-COD60 Chemical Oxygen Demand (COD) High Chloride Reflux Digestion Instrument, which integrates digestion, condensation, reflux, and absorption. This instrument eliminates the interference of high chloride ion content on COD determination and can serve as a standard instrument for COD determination in water and wastewater with a chloride ion concentration greater than 1000mg/L and less than 50000mg/L, and a COD concentration greater than 10mg/L. It can be widely used for COD determination in wastewater from oil fields, coastal refineries, oil depots, chlor-alkali plants, and deep-sea wastewater discharge. Technical Specifications: Product model: KN-COD60 Digestion unit: 6 digestion units, single-hole single-control Digestion volume: 500ml, threaded connection with PTFE joint Temperature range: room temperature to 300℃ (adjustable) Time range: 0-999 minutes (adjustable) Heating method: ceramic infrared radiator plus microcrystalline panel Display mode: LCD Chinese display Rated voltage: AC ~ 220V ± 10% 50Hz Endpoint control: Time-controlled digestion endpoint, automatic switching of nitrogen flow rate Resistance to chlorine interference: No effect when [Cl-] is between 1000mg/L and 50000mg/L COD measurement range: 10mg/L≤COD≤700mg/L (undiluted) Nitrogen blowing system: proportional valve, digital adjustment of nitrogen flow rate Nitrogen flow parameters: flow control range 0-50mL/min, control accuracy ±1.5%F.S, repeatability ±0.2%F.S Absorption device: A secondary absorption device is used to guide the chlorine gas out and react with the absorption liquid Cooling method: Built-in automatic cooling circulation of cooling water, compressor refrigeration Overall dimensions: 900×450×600 (mm)
