Automatic metering and titration unit DT 20

Dosage:
Time optimized COD interval dosage. The addition of sulfuric acid is carried out in several steps, while the samples are constantly cooled and stirred. This method accelerates sample preparation and at the same time prevents non-standard overheating of the samples during acid addition.
Titration:
Instead of the commonly known over-titration, the behr-specific dynamic titration guarantees the exact end-point recognition, even in the case of the typical COD edge steepness, and thus particularly accurate test results
