Rosemount Analytical 1054A Percent Concentration Analyzer

The Rosemount Analytical 1054A Percent Concentration Analyzer is a microprocessor-based analyzer that continuously determines the percent concentration of a process solution by integrating sensor data, and it is part of the Rosemount 1054A family that can also measure pH, ORP, conductivity, dissolved oxygen, or total free chlorine depending on sensor configuration. The instrument is designed for rugged industrial and municipal environments and supports DIN-standard panel mounting, with a compact 0.7-inch digital display for on-site readouts. When paired with the appropriate Rosemount sensors, the 1054A delivers direct percent-concentration readings that support chemical dosing control, product quality monitoring, and regulatory compliance in applications such as water treatment, chemical processing, and industrial manufacturing. The model emphasizes practical integration with existing Rosemount instrumentation and control systems, enabling reliable, real-time concentration monitoring without requiring multiple separate instruments. Designed to work with Rosemount sensor configurations as part of the Rosemount Analytical family. Typical installations involve monitoring feed or product concentrations in water treatment, chemical manufacturing, and other process environments where precise percent concentration control is critical.
