COD Tester
Brief introduction
Multi-parameter water quality detection meter is a water detection meter which is promoted by Zhejiang Lohand in 2017.The Multi-parameter water quality detection meter adopts the spectrophotometry to measure the COD,Ammonia Nitrogen,Total Nitrogen and Total Phosphorus.
The instrument is strictly produced in accordance with ISO9001 2015 quality management system.And has been passed the strict test before leaving the factory.
COD: In environmental chemistry, the chemical oxygen demand (COD) is an indicative measure of the amount of oxygen that can be consumed by reactions in a measured solution. It is commonly expressed in mass of oxygen consumed over volume of solution which in SI units is milligrams per liter (mg/L). A COD test can be used to easily quantify the amount of organics in water.
Ammonia nitrogen means nitrogen present in the form of free ammonia(NH3)and ammonium ions(NH4)in water. The nitrogen content of animal organic compounds is generally higher than that of vegetable organic compounds. At the same time, nitrogen-containing organic matter in human and animal feces is very unstable and easily decomposed into ammonia. Therefore, when the content of ammonia nitrogen in water increases, it refers to the nitride in the form of ammonia or ammonium ions.
