Where AccuSeries can be used
The correct configuration depends on the analyte, concentration range, sample matrix, required method and process objective.
Wastewater and effluent
Online multi-parameter chemistry for municipal wastewater, industrial effluent and challenging samples.
Chemical and process industries
Configurable measurement for chemical, refining, gas-abatement, plating and manufacturing processes.
Water, power and utilities
Flexible wet-chemistry analysis for drinking water, boiler water, cooling water and treatment duties.
Online measurement does not replace required laboratory analysis
Accredited laboratory analysis and statutory sampling remain necessary where required by the application or regulation.
AccuSeries Application Notes
Explore four practical application notes showing how AccuSeries supports demanding water and process measurements. Review more AccuSeries applications or contact PMA to discuss your process.
Refinery wastewater effluent monitoring
Track alkalinity, ammonia, nitrate and selected metals in refinery effluent using automated AccuSeries wet chemistry.
CMP wastewater treatment in semiconductor manufacturing

Which wet-chemistry method does AccuSeries use?
AccuSeries can use colorimetry, color titration, potentiometric titration, ion-selective electrodes or direct measurement according to the application.
How is sample colour managed?
Dual-wavelength colorimetry and automatic blanking can compensate for background colour and turbidity in suitable methods.
Can methods match laboratory procedures?
Methods can be configured around recognised EPA, ISO or ASTM procedures and application-specific requirements.
Why does application review matter?
Sample matrix, analyte, range, interferences and process objectives determine the right method and configuration.
