Technické údaje

Alarm: 1 x malfunctioning, 4 x user-configurable, max. 24 VDC/0.5 A, potential free contacts
Certifikace: CE compliant / UL certified
Digitální výstupy: Modbus RS485
Doba cyklu : 10 min (dilution + 5 min.) per parameter
Earth connection: Dry and clean earth pole with low impedance (< 1 Ohm) using an earth cable of > 2.5 mm²
Hmotnost: 25 kg
Instrument air: Dry and oil free according to ISA-S7.0.01-1996 quality standard for instrument air
Interference : Calmagite/EDTA method: Some metal ions interfere by causing fading or indistinct end points or by stoichiometric consumption of EDTA.
HNB method: dissolved Copper Cu(II) > 2 mg/L, Iron Fe(II) > 20 mg/L, Manganese > 10 mg/L, Zinc > 5 mg/L, Lead > 5 mg/L, Aluminium > 5 mg/L and Tin Sn(IV) interfere. Orthophosphate precipitates Calcium at the pH of the test. Strontium and Barium give a positive interference and alkalinity in excess of 300 mg/L may cause an indistinct end point in hard waters.
Large amounts of colour and turbidity interfere. Fats, oil, proteins, surfactants and tar.
