The “cod” image will flash for 3 seconds, then the sample test outcome will look inside the display as part per million COD. History the test outcome.

The COD test really should be regarded as an impartial measure from the natural and organic issue in a wastewater sample rather than a substitute for the BOD test.

Chemical Oxygen Demand is actually a critical metric while in the wastewater market and is often described as milligrams of oxygen consumed for each liter of sample (mg/L COD).

Safe the cap on to Every COD vial. Be sure never to overtighten the cap mainly because it could hurt the closure.

The FERITSCOPE® DMP®30 handheld measuring gauge is the correct Answer for identifying the ferrite content material and martensite written content swiftly and non-destructively.

The transform in likely or latest produced with the ion-selective electrode is proportional on the concentration from the concentrate on ion in the h2o.

Take note the excellence amongst this and the opposite oxygen demand test (BOD). COD is when all products are fully chemically oxidized; BOD is simply that content and that is oxidized by (often uncooperative) microbes over a duration of five days. Any approach that may be capable of oxidizing compounds and lets the quantity of oxidation being measured could theoretically be used to determine COD. The dichromate ion (Cr2O72-) has confirmed itself to become very best suited to basic goal COD and is required here in all approved procedures.
