• Conductivity, resistivity, TDS and salinity modes
• Special pure water mode for ultra low conductivity measurements
• Storage of 500 results with built in data logger
• Infra-red data link (IrDA) for connection to printer and RS232 link to connect to printer or PC via DataWay software
The 4520 is a high specification laboratory conductivity /resistivity/TDS/salinity and temperature meter that offers additional accuracy with 1, 2 or 3 point conductivity calibration across the wide measurement range of 0 to 19.99S. The dedicated "pure water" mode ensures the optimum accuracy for this difficult application.
