KHCOD-8G High Chlorine Wastewater Standard COD Digestion Device Introduction: The KHCOD-8G high chloride wastewater standard COD digestion device adopts microcomputer technology for timed control of the heating plate, which can simultaneously heat and digest 8 250ml conical flask reflux devices. The instrument uses a glass burr reflux tube instead of a spherical reflux tube, and uses air cooling technology instead of tap water cooling, which can save water and standardize the instrument. Chemical solution preparation, operation, and COD calculation of the instrument. Suitable for the determination of COD in wastewater from oil fields, coastal oil refineries, oil depots, chlor alkali plants, and deep-sea wastewater discharge. Technical parameters: 1. Anti chlorine interference: 1000~20000mg/L Nitrogen flow rate: 6-60mL/min 3. Measurement range: ≤ 1000mg/L (greater than dilution) 4. Digestion time: 2 hours and 30 minutes (time adjustable) 5. Digestion volume: 250mL 6. Measurement error: ≤ 500mg/L, relative standard deviation not greater than 5.0; ≤ 1000mg/L, relative standard deviation not greater than 8.0% 7. Heating power: 1600W (220V, 50HZ) 8. Cooling method: dual fan air cooling and water cooling 9. Heating table of microcrystalline plate, making 8 samples
