Automatic cleaning: Yes
Calibration: Automatic, 2-point; frequency freely programmable
Certifications: CE compliant / ETL certified
Cycle Time: 10 min (dilution + 5 min.)
Demineralised water: For rinsing / dilution
Digital outputs: Optional: Modbus (TCP/IP, RS485)
Dimensions (H x W x D): 690 mm x 465 mm x 330 mm
Drain: Atmospheric pressure, vented, min. Ø 32 mm
Earth connection: Dry and clean earth pole with low impedance (< 1 Ohm) using an earth cable of > 2.5 mm²
Instrument air: Dry and oil free according to ISA-S7.0.01-1996 quality standard for instrument air
Interferences: 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.
