FEATURES		BENEFITS
Ultra-Pure Compensation		Ultra-pure water temperature compensation insures accuracy at conductivities of less than 1 NS/cm.
Wide Measurement Range		Wide range of measurement covers applications from ultra-pure water to liquids with conductivity up to 10,OOONS/cm.
Universal Scaling		Incorporates universal scaling to provide the best resolution for your application requirement. Measurement range can be scaled to NS/cm, pS/m, mS/cm, mS/m, Mohm-cm, TDS and ppm.
m On-Line Diagnostics		Comprehensive diagnostics continuously verify analyzer operation of the entire sensing loop with built-in software protection.
