Online Caustic and Sodium Hydroxide Analyser
Measure caustic strength directly for scrubber, chemical-processing and concentration-control applications.
Online Caustic and Sodium Hydroxide Analyser with AccuSeries
AccuSeries titration can provide direct online measurement of caustic or sodium hydroxide concentration in suitable process samples. This supports scrubber control, chemical dosing and concentration management where pH alone does not describe caustic strength. Read PMA’s independent caustic and sodium hydroxide application guide for wider measurement 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 caustic and sodium hydroxide analysis
AccuSeries automates sample handling, method execution, result calculation and reporting for configured caustic and sodium hydroxide measurement while operators monitor status through the graphical interface.

- Automatic calibration
- Automatic cleaning
A controlled caustic and sodium hydroxide measurement sequence
Each caustic and sodium hydroxide 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 caustic and sodium hydroxide analysis.
02.
Add method reagents
The programmed sequence doses the reagents required for the selected caustic and sodium hydroxide method.
03.
Run the configured method
The approved caustic and sodium hydroxide method proceeds under controlled conditions.
04.
Calculate the caustic and sodium hydroxide result
The measured response is converted into the configured caustic and sodium hydroxide concentration result.
05.
Calibrate
Automatic calibration can run against configured caustic and sodium hydroxide standards at selected intervals.
06.
Clean
Automatic cleaning supports the caustic and sodium hydroxide measurement system between planned maintenance visits.
Designed for practical caustic and sodium hydroxide monitoring
The modular AccuSeries design keeps wet-chemistry components accessible while caustic and sodium hydroxide results, diagnostics and method controls remain available through the interface.
Touchscreen
Clear access to caustic and sodium hydroxide results, status and analyser functions.
Data logging
Integrated caustic and sodium hydroxide result storage with USB export.
Separate compartments
Electronic and wet-chemistry sections are physically separated.
Low reagent use
Small reagent volumes help control caustic and sodium hydroxide measurement costs.
