AQUALYTIC®
AL200 COD VARIO Photometer

For determination of the chemical oxygen demand (ST-CSB). The AQUALYTIC® photometer COD VARIO is suitable for waste-water analysis due to its 3 measuring ranges. The unit ensures operational safety and comfort.
  • User-friendly keypad.
  • Suppression of chloride interference up to 1000 mg / l (LR and MR) and up to 10000 mg / l (HR).
  • Waterproof as defined in IP68, 1 h at 0.1 m.

The waste-water parameter CSB:
The chemical oxygen demand, ST-COD-value (ST = small scale sealed tube), of a sample is determined by the dichromate method. The result is a reference value for the theoretical oxygen demand, that is the amount of oxygen consumed which is needed in a total chemical oxidation of the organic constituents present in the water.

Setup AL200COD VARIO:
The COD setup COD VARIO allows for precise water analyses with min. effort. After adding 2 ml of the sample to an AQUALYTIC® COD VARIO tube test, the test is heated to 150 °C in a reactor for 2 h, cooled down and measured in a photometer afterwards.
