Features: 1 can automate the entire measurement process; 2. automatic loading system can be set dosing procedures make the operation more convenient; 3. digestion process can be set to 10 laboratories cod detector customize a button. simple operation and fast; 4. Unique "COD" mode ensures that the sample temperature reaches the set temperature within 10min of; 5. with Windows software that can be transmitted between time-temperature curve instrument or instruments and computers; 6. All automatic titration can be titrated every 12 samples; 7. five optional automatic titration mode cod detector laboratory supplies, measurement results more accurate; 8. You can print an order form of images titration, the second derivative curve, and printable measurement data; 9. Optional metrology laboratory cod sulfate funnel direct detector simplifies adding sulfuric acid to the sample operations; 10. Optional chloride absorber for high salt content of the water sample measurement. 11. The product complies with DIN / DEV, EN, ISO standards. Product Principle: adding water samples known amount of potassium dichromate solution and in acid medium to silver as a catalyst laboratory cod detector, after boiling reflux to test the Spirit of ferrous indicator, with sulfuric acid the amount of potassium dichromate consumed ferrous ammonium sulfate, ferrous ammonium titration in water samples have not been converted into consumption reduction of oxygen concentration in the sample is the COD value of organic matter. Laboratory cod detector manufacturers, laboratories cod detector, even by the Guangzhou Science and Technology of China Environmental Protection Technology Co. even. Even China Guangzhou Environmental Protection Technology Co., Ltd. (www.gdlhkj.com) strong, credible, in Guangzhou analytical instruments industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead even the Chinese science and technology into the brilliant and you work for a better future!
