The Rosemount Analytical Portable Conductivity Validation Instrument is the ideal tool for documenting high purity water quality. This unit can be used as a standard to meet validation requirements by organizations such as the FDA1 and USP2 for pharmaceutical and biotechnology applications. This instrument comes loop-calibrated to NIST traceable standards, which makes it suitable for the pharmaceutical, semiconductor, and utility industries. The portable conductivity validation instrument consists of a Rosemount Analytical Model 1056 Analyzer, and a Model 404-11-17 Stainless Steel flow-through cell with a 0.01/cm cell constant. It includes all the cabling and tubing necessary for easy connection to your water system. Available ranges for ultra-pure water include 0-50μS/cm for conductivity and 0-18.2 MΩ for resistivity.
