HCA-102 standard COD digester Introduction: The HCA-102 standard COD digester follows the basic principles of ISO and GB11914-89 standards, ensuring a 2-hour digestion operation with reflux heating and micro boiling. The preparation and addition of reagent solutions are consistent with the national standard method, ensuring reliable and accurate analysis results. HCA-102 standard COD digester -8 tubes use microcomputer technology for timed control of heating electric furnace, which can simultaneously heat 8 250ML conical digestion reflux devices. To achieve the goals of energy conservation, reducing power load, and improving efficiency. The HCA-102 standard COD digester uses a glass burr reflux tube instead of a spherical reflux tube, and uses air cooling technology instead of tap water reflux cooling. Static water is used as auxiliary cooling at the end of the condenser tube, which can save water, standardize the instrument, and improve the safety of instrument use. Features: The wavy strip heating wire of the flat electric furnace plate is made of a new type of rare earth alloy material, which has an extremely long service life. The surface of the electric furnace plate is covered with a glass panel that can withstand high temperatures up to 800 ℃. When heated, the surface of the electric furnace heats up evenly, and the heating and cooling rates are fast. 2. The electric furnace plate uses a new type of high-temperature resistant inorganic environmentally friendly insulation material, which reduces heat loss in the bottom plate and surrounding areas, ensures uniform heating and thermal conductivity, and has higher thermal efficiency. 3. The flat electric furnace plate has a heat-resistant glass panel that is flat, smooth, and easy to clean; If the surface is contaminated, simply wipe it dry with a cloth to reduce damage to the instrument caused by improper operation. 4. Improved glass burr reflux tube and heat dissipation system, with good digestion reflux effect, ensure the parallelism and accuracy of sample digestion results. 5. Corresponding to different heating powers selected by the user, the surface heating temperature of the electric furnace can be displayed. 6. The digestion time can be set. After digestion is complete, the instrument automatically stops heating, and the instrument fan continues to work for half an hour to assist in sample cooling. It can be left unattended. 7. Energy and water conservation, safety and reliability have improved the work efficiency of operators. Technical Specifications: Measurement range: 10-700mg/L, diluted water samples greater than 700mg/L for measurement Dissolving time: 10 minutes -2 hours and 30 minutes (users can choose their own heating time) 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% Environmental temperature: ≤ 35 ℃ Dissolve 8 samples (using a 250mL conical flask with a 24 # grinding mouth) Heating power: ≤ 1600W (AC 220V, 50HZ, users can choose their own heating power) Instrument size: 45cm (L) * 35cm (W) * 65cm (H)
