This unit
The Emerson Rosemount Analytical 54EC-01-09 is a conductivity/resistivity analyzer and controller for inline process monitoring and control of liquid solutions. It measures conductivity, resistivity, and percent concentration using contacting or inductive sensors, delivering ±0.5% accuracy with contacting probes across a 0–20,000 µS/cm range. The unit accommodates toroidal inductive sensors to 2 S/cm with ±1% accuracy and supports temperature measurement from −15 to 200°C. Temperature compensation operates automatically or manually, with selectable correction algorithms for high-purity water, cation conductivity, or linear temperature coefficients (0.0 to 5.00%/°C).
