TOC actions the overall carbon material, like each natural and organic and inorganic carbon, even though COD specifically focuses on the oxidizable organic and natural content.
The potential difference between the reference electrode along with the pH electrode is utilized to ascertain the pH worth of the h2o sample.
It can be applied to supply an indication of the level of pollution in a very h2o system, Particularly following a h2o therapy process.
Insert the COD reagent blank to the sample compartment and press the Zero/Test essential. The “cod” symbol will flash for roughly 8 seconds.
Chemical Oxygen Demand is an important evaluate in comprehension the level of natural and organic pollutants present in area drinking water or wastewater. It truly is expressed in milligrams for each liter (mg/L), which implies the mass of oxygen consumed for every liter of Alternative.
It's not at all recommended to evaluate the vials ahead of allowing them neat to area temperature. The measurement could be inaccurate, as well as a warm reagent vial could harm the digital instrument.
