Околна температура: 10 - 30 °C ±4 °C deviation at 5 - 95% relative humidity (non-condensing)
Параметър: COD
Проба, дебит: 100 - 300 mL/min
Проба, качество: Maximum particle size 100 µm, < 0.1 g/L; Turbidity < 50 NTU
Проба: налягане: By external overflow vessel
Размери (В х Ш х Д): 690 мм x 465 мм x 330 мм

Смущения: Chloride > 1 g/L, inorganic reducing agents such as nitrites, sulphides and iron(II) will increase the result, aromatic hydrocarbons and pyridine are not oxidized to any appreciable extent. Some very volatile organic substances may escape the oxidation by evaporation. Straight chain aliphatic compounds are effectively oxidised by the silver sulphate/sulphuric acid solution. Fats, oil, proteins, surfactants and tar.
