KN-COD12K COD traditional reflux automatic digestion instrument Introduction: This instrument adopts COD reflux digestion method, and the water sample reaction is complete. During the digestion process, air cooling reflux mode is used instead of water cooling reflux mode to save water resources. During cooling, add an air cooling system to save detection time. According to the national standard method HJ_828-2017 for the determination of chemical oxygen demand (potassium dichromate method), an intelligent mode is added in addition to the manual operation mode to complete the digestion and cooling process with one click operation. Equipped with dedicated condenser tube brackets for safe operation. Characteristics: 1. Operation mode: The instrument is set to manual and intelligent modes, allowing operators to freely choose the experimental operation process 2. Protection method: The bottom protective cover of the heating plate effectively protects the safety of experimental operators 3. Display mode: LCD display, user-friendly menu design, enabling operators to master the use of the instrument 4. Automatic intelligent mode: The heating time can be set, and after digestion is completed, the instrument automatically stops heating without the need for a dedicated person to supervise 5. Intelligent mode: Intelligent heating system, heating time and cooling time programs have been set, allowing the experimental process to be completed with just one click 6. Cooling mode: Equipped with a dual channel cooling system, the cooling effect is consistent with the condensation of flowing water 7. Heating material: stainless steel metal heating plate, uniform temperature, stable service life 8. Heating surface material: stainless steel panel, acid resistant and corrosion-resistant, leaving no water stains Technical Specifications: Product model: KN-COD12K Cooling method: Dual air circulation system Control system: manual or automatic intelligent mode Heating method: All metal heating plate Protection method: Heating plate protection cover, anti scald protection Pipe rack: with condenser pipe support at the top Internal temperature of heating plate: room temperature~400 ℃ Measurement range: 30-700mg/L, 30-10000mg/L (diluted water sample) Measurement error: Potassium hydrogen phthalate standard solution (500mg/L), relative standard deviation not exceeding 5.0% Industrial organic wastewater (500mg/L), with a relative standard deviation not exceeding 8.0% Reflux digestion time: 2 hours Batch processing capacity: 6 Timing range: 1 minute to 96 hours Timing accuracy: 0.2 seconds/hour Instrument size: (455 × 283 × 604) mm Instrument weight: 16.7 Kg Display screen: LCD Environmental temperature: 5-40 ℃ Environmental humidity: Relative humidity<85% (no condensation) Working power supply: AC220V/50HZ Power: 1600W
