COD Tester

Brief introduction

Multi-parameter water quality detection meter is a water detection meter which is promoted by Hangzhou Lohand in 2017. Rapid digestion spectrophotometry, Nexler’s reagent spectrophotometry, and molybdic acid spectrophotometry were used to test the concentrations of

COD, ammonia nitrogen in the water.

The reaction is used by a digestion tube. The digestion and color comparison are combined into one.

The instrument is strictly produced in accordance with ISO9001 2015 quality management system. And has 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 the mass of oxygen consumed over the volume of solution which in SI units is milligrams per liter (mg/L). A COD test can be used to easily quantify the number 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.
