Dimensiuni (Înălţime x Lăţime x Adâncime): 690 mm x 465 mm x 330 mm
Domeniu de măsurare: 1 - 20 mg/L O2
  1 - 20 mg/L O₂
Earth connection: Dry and clean earth pole with low impedance (< 1 Ohm) using an earth cable of > 2.5 mm²
Esantion: presiune: By external overflow vessel
Garanţie: 24 luni
Greutate: 25 kg
Iesiri analogice: Active 4 - 20 mA max. 500 Ohm load, standard 1, max. 8 (option)
Instrument air: Dry and oil free according to ISA-S7.0.01-1996 quality standard for instrument air
Interferente: 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.
