COD Quick Tests For Even More Applications

With no less than 14 different COD test kits WTW (Germany) covers the full measuring range of the most important sum parameter. Concentrations from 4 to 90,000 mg/l COD can be determined comfortably and reliably.

Depending on application and range, the kits are ISO and US EPA compliant and meet the German standard DIN 38409 H44. Some kits allow an increased content of chloride for measurements in the ultra-high range up to 90,000 mg/l.

Due to this wide choice of measuring ranges, sample dilution is not required, thus eliminating a potential source of errors. Another essential advantage of COD test kits is the closed test system and the low volume of required reagent content in the vials, thus contributing to precise measuring results and to environmental protection.

The test kits can be used with WTW’s photoFlex colorimeters and photoLab photometers for applications ranging from waste water before and after treatment to industrial and production plants for internal control.
