Online Sulphite Analyser
Monitor sulphite in boiler water, treatment chemicals and industrial processes with automated wet chemistry.
Online Sulphite Analyser with AccuSeries
AccuSeries can be configured for sulphite measurement in suitable boiler-water, treatment and industrial process applications. PMA reviews the range, oxidation risk, sample handling and method before specification. Review PMA’s AccuSeries overview for wider product and application context.
Every configuration is application-specific. Confirm the analyte, expected range, sample composition, temperature, suspended solids, number of streams and required outputs with PMA before selection. Explore the AccuSeries online wet chemistry analyser and its water and process applications.
Programmable online sulphite analysis
AccuSeries automates sample handling, method execution, result calculation and reporting for configured sulphite measurement while operators monitor status through the graphical interface.
01 / CONFIGURED METHOD
A method matched to sulphite and the process
Each analyser is configured around sulphite, the required range, sample matrix and recognised analytical method.
- Approved method for sulphite
- Configured range and sample matrix
- Method-specific sulphite result calculation
02 / AUTOMATIC OPERATION
Sampling, calibration and cleaning
Programmable routines support repeatable sulphite measurement while diagnostics and alarms alert users to changing analyser or process conditions.
- Automatic sampling
- Automatic calibration
- Automatic cleaning
A controlled sulphite measurement sequence
Each sulphite result follows a configured sampling, reagent, measurement, calculation and maintenance sequence.
01.
Capture the sample
The internal fast loop and sample mechanism provide a representative, consistent sample volume for sulphite analysis.
02.
Add method reagents
The programmed sequence doses the reagents required for the selected sulphite method.
03.
Run the configured method
The approved sulphite method proceeds under controlled conditions.
04.
Calculate the sulphite result
The measured response is converted into the configured sulphite concentration result.
05.
Calibrate
Automatic calibration can run against configured sulphite standards at selected intervals.
06.
Clean
Automatic cleaning supports the sulphite measurement system between planned maintenance visits.
Designed for practical sulphite monitoring
The modular AccuSeries design keeps wet-chemistry components accessible while sulphite results, diagnostics and method controls remain available through the interface.
Touchscreen
Clear access to sulphite results, status and analyser functions.
Data logging
Integrated sulphite result storage with USB export.
Separate compartments
Electronic and wet-chemistry sections are physically separated.
Low reagent use
Small reagent volumes help control sulphite measurement costs.
