4520
Part code: 452 001
• 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
Bench Conductivity/TDS Meter
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.
