CA-G300 Intelligent High Chlorine Wastewater COD Digestion Instrument Introduction: The CA-G300 intelligent COD digestion instrument for high chlorine wastewater converts the amount of potassium dichromate consumed in the water sample into the corresponding mass concentration of oxygen under certain conditions, which is the mass concentration of oxygen corresponding to the chlorine gas generated by the oxidized chloride ions in the water sample, which is the chloride ion correction value. The difference between the corrected values of CODcr and chloride ions is the CODcr of the measured water sample. Suitable for the digestion of CODcr in water and wastewater with chloride ion concentrations greater than 1000mg/L, less than 50000mg/L, and CODcr greater than 10mg/L. Product use: Used for sample digestion of chemical oxygen demand in high chlorine water bodies (water and wastewater, chloride ion concentration greater than 1000mg/L). Technical parameters: Host composition: heating and digestion intelligent control system, automatic endpoint control system, refrigeration cycle system, nitrogen blowing control system, chlorine absorption device Intelligent control system for heating and digestion: Automatic endpoint control system: High precision nitrogen flow metering module, single hole single control, constant flow blowing, automatically stop heating when the set digestion time is reached, nitrogen flow automatically switches to static flow without human intervention. Chlorine absorption device: equipped with a chlorine absorption device, the absorption liquid reacts fully, and the absorption device is located in front of the machine, making it easy to operate! Refrigeration cycle system: Equipped with a built-in compressor cooling system and internal water circulation for cooling, without the need for external water sources. It needs to have an automatic one click water addition function and automatically stop when the liquid level is reached. Nitrogen blowing control system: Adopting imported proportional valve, nitrogen flow rate is digitally adjusted, and flow rate is automatically closed-loop controlled according to pressure; Temperature range: (0-450) ℃ (adjustable) Temperature control accuracy: ± 2 ℃ Time control: 0-999 minutes (adjustable) Heating time: 5-8 minutes Intelligent operating system: Intelligent microcomputer operation, using a 7-inch color touch screen, the display screen is fixed in front of the machine (machine appearance or relevant proof documents need to be provided), convenient for experimental personnel to operate, and can set the required parameters for experiments independently; The host has a storage and printing function, and experimental data can be checked! Power supply: AC 220V, 50Hz, Environmental temperature: 10-35 ℃, Environmental humidity: < 60% Instrument size (length, width, height): 900mm * 470mm * 600mm
