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.
