CA-06 standard microcrystalline COD digester Introduction: The CA-06 standard microcrystalline COD digester uses a glass burr reflux tube instead of a spherical reflux tube, and uses air cooling technology instead of tap water cooling. The cooling part is mainly completed by a burr condenser tube and a fan. The upper part of the condenser tube is spherical, and the catalyst is added here to prevent the instantaneous volatilization of light components in the sample. The lower part is "burr" shaped, with three opposite spherical condenser tubes protruding from the condenser tube wall on a plane. In addition, the dual effect of the cooling water inside the upper spherical reflux tube and the fan inside the machine ensures the reflux cooling of the sample. Complies with the dichromate method of the Ministry of Environmental Protection of China (HJ828-2017), replacing the dichromate method of GB11914-89. Features: 1. The microcrystalline panel is flat, smooth, and easy to clean; If the surface is contaminated, wipe it dry with a cloth to reduce damage to the instrument caused by improper operation. 2. The new type of glass burr reflux tube and heat dissipation system ensure the parallelism and accuracy of sample digestion results with good digestion reflux effect. 3. Digital display of microcrystalline panel temperature, temperature range (between 100 ℃ -440 ℃) 4. Digital display of digestion time: The digestion time is between 0-180 minutes. After digestion, the instrument automatically stops heating, the heating indicator light goes out, and there is a warning sound. The fan is used for cooling the digestion sample. After a delay of 120 minutes, it automatically stops and the cooling indicator light goes out. 6. It saves electricity and water, is safe and reliable, and improves the work efficiency of operators. Technical parameters: Measurement range: 0-700700-10000mg/L (diluted with water sample) Measurement time: no more than 2 hours Measurement error: Potassium hydrogen phthalate standard solution (500mg/L), relative standard deviation not exceeding 5.0%; Industrial organic wastewater (500mg/L), relative standard deviation not exceeding 8.0% Environmental temperature: room temperature~40 ℃ Power supply voltage: 220V 50HZ Heating power: 1600W (AC 220V ± 22V, 50Hz) Sample quantity: 6 (using 24 # ground 250ml conical flask)
