About Us
Rosemount Analytical, one of Emerson's leading process management companies, is the world's premier supplier of technologies for liquid and combustion analysis, process analysis, gas measurement, and emissions monitoring. With an 80-year legacy of manufacturing liquid and gas analytical products that have revolutionized the process industries, we continue to provide real, quantifiable analytical solutions.
For the water and wastewater industry, we offer products that improve operations in many types of plant configurations and assist with monitoring for regulation compliance.

A typical drinking water plants treat water in multiple stages and at each one, liquid analytical can help: from monitoring ozone and chlorine for disinfection to turbidity measurement for reporting purposes and indicating filter performance. Addition of chemicals can be controlled by monitoring the pH level to reduce cost and eliminate waste.
From the plant to the distribution system, and on to wastewater processing, count on Rosemount sensors and analyzers to provide a solution. Wastewater treatment also depends on liquid analytical measurements to monitor the physical, chemical and biological treatment processes. The chief measurements are: pH, ORP, dissolved oxygen, chlorination and dechlorination.
Because so much is at stake, you need a partner that can deliver the best in knowledge and systems and do it quickly, thoroughly and cost-effectively. The professionals at Rosemount Analytical are ready to apply their decades of experience to provide a customized solution to meet your specific needs.
Rosemount Analytical is part of Emerson Process Management. Emerson Process Management, an Emerson business, is a leader in helping businesses automate their production, processing and distribution in the life sciences, chemical, oil and gas, refining, pulp and paper, power, food and beverage, and other industries.
