Online Alkalinity Analyser
Track buffering capacity online to support wastewater treatment, dosing control and stable biological processes.
Online Alkalinity Analyser with AccuSeries
Online alkalinity measurement gives operators a direct view of the water’s buffering capacity rather than relying on pH alone. An AccuSeries titration method can support chemical dosing, biological treatment and industrial wastewater control when the expected range and sample matrix are confirmed. Read PMA’s independent alkalinity 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 alkalinity analysis
AccuSeries automates sample handling, method execution, result calculation and reporting for configured alkalinity measurement while operators monitor status through the graphical interface.
01 / CONFIGURED METHOD
A method matched to alkalinity and the process
Each analyser is configured around alkalinity, the required range, sample matrix and recognised analytical method.
- Approved method for alkalinity
- Configured range and sample matrix
- Method-specific alkalinity result calculation
02 / AUTOMATIC OPERATION
Sampling, calibration and cleaning
Programmable routines support repeatable alkalinity measurement while diagnostics and alarms alert users to changing analyser or process conditions.
- Automatic sampling
- Automatic calibration
- Automatic cleaning
A controlled alkalinity measurement sequence
Each alkalinity 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 alkalinity analysis.
02.
Add method reagents
The programmed sequence doses the reagents required for the selected alkalinity method.
03.
Run the configured method
The approved alkalinity method proceeds under controlled conditions.
04.
Calculate the alkalinity result
The measured response is converted into the configured alkalinity concentration result.
05.
Calibrate
Automatic calibration can run against configured alkalinity standards at selected intervals.
06.
Clean
Automatic cleaning supports the alkalinity measurement system between planned maintenance visits.
Designed for practical alkalinity monitoring
The modular AccuSeries design keeps wet-chemistry components accessible while alkalinity results, diagnostics and method controls remain available through the interface.
Touchscreen
Clear access to alkalinity results, status and analyser functions.
Data logging
Integrated alkalinity result storage with USB export.
Separate compartments
Electronic and wet-chemistry sections are physically separated.
Low reagent use
Small reagent volumes help control alkalinity measurement costs.
Alkalinity technical specifications
Core AccuSeries information for alkalinity application and specification review.
| Measurement principle | Application-specific approved method |
| Variables | Alkalinity, range and sample matrix dependent; approved method |
| Typical response | T-90 typically 3 to 15 minutes; method dependent |
| Power supply | 24 VDC or 90 to 240 VAC; 310 W |
| Sampling | Single stream or up to 6 streams |
| Cabinet | Painted 304 stainless steel |
| Protection grade | IP66; NEMA 4X |
| Outputs | 4-20 mA; optional Modbus TCP/IP or serial |
| Automatic functions | Sampling, calibration, validation and post-wash as configured |
Alkalinity, range, sample conditions, wetted materials and final specifications must be confirmed for the configured method before procurement.
Discuss your alkalinity measurement
Tell PMA about your sample, measuring range and process objective. An applications engineer will review whether AccuSeries and an available analytical method are appropriate.
