Certifikácia: CE compliant / UL certified
Demineralised water: For rinsing
Detekčný limit: ≤ 200 µg/L
Digitálne výstupy: Optional: Modbus (TCP/IP, RS485)
Doba cyklu : 30 min including digestion of 10 min (standard)
Earth connection: Dry and clean earth pole with low impedance (< 1 Ohm) using an earth cable of > 2.5 mm²
Hmotnosť: 25 kg
Chladící voda: Flow rate approx. 5 L/h; temperature max. 30 °C; pressure max. 0.5 bar
Instrument air: Dry and oil free according to ISA-S7.0.01-1996 quality standard for instrument air
Interferencie: Antimony (III), Bismuth (III), Chloroplatinate, Gold (III), Iron (III), Lead (II), Mercury (II), Metavanadate, and Silver (I) can precipitate with Nitrate. The presence of Copper (II) may decompose the diazonium salt which results in a low result. Strong oxidising agents. NCl₃ results in a false red colour. Large amounts of colour and turbidity interfere. Fats, oil, proteins, surfactants and tar.
