Online Phosphate and Phosphorus Analyser
Track phosphate or phosphorus for dosing control, wastewater treatment and environmental monitoring.

Online Phosphate and Phosphorus Analyser with AccuSeries
AccuSeries can be configured for online phosphate or phosphorus measurement in water-treatment, wastewater and industrial applications. Automated wet chemistry can support chemical dosing, nutrient removal and discharge monitoring when the correct fraction and range are defined. Read PMAโs independent phosphate and phosphorus application guide for wider measurement context.
Every configuration is application-specific. Confirm the phosphate or phosphorus fraction, expected range, sample composition, temperature, suspended solids, number of streams and required outputs with PMA before selection. Read the online phosphate analysis guide for wastewater treatment and, where iron-based dosing is used, review iron monitoring at sewage treatment works. Explore the AccuSeries online wet chemistry analyser and its water and process applications.
Programmable online phosphate and phosphorus analysis
AccuSeries automates sample handling, method execution, result calculation and reporting for configured phosphate and phosphorus measurement while operators monitor status through the graphical interface.
01 / CONFIGURED METHOD
A method matched to phosphate and phosphorus and the process
Each analyser is configured around phosphate and phosphorus, the required range, sample matrix and recognised analytical method.
- Approved method for phosphate and phosphorus
- Configured range and sample matrix
- Method-specific phosphate and phosphorus result calculation
02 / AUTOMATIC OPERATION
Sampling, calibration and cleaning
Programmable routines support repeatable phosphate and phosphorus measurement while diagnostics and alarms alert users to changing analyser or process conditions.
- Automatic sampling
- Automatic calibration
- Automatic cleaning
A controlled phosphate and phosphorus measurement sequence
Each phosphate and phosphorus 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 phosphate and phosphorus analysis.
02.
Add method reagents
The programmed sequence doses the reagents required for the selected phosphate and phosphorus method.
03.
Run the configured method
The approved phosphate and phosphorus method proceeds under controlled conditions.
04.
Calculate the phosphate and phosphorus result
The measured response is converted into the configured phosphate and phosphorus concentration result.
05.
Calibrate
Automatic calibration can run against configured phosphate and phosphorus standards at selected intervals.
06.
Clean
Automatic cleaning supports the phosphate and phosphorus measurement system between planned maintenance visits.
Designed for practical phosphate and phosphorus monitoring
The modular AccuSeries design keeps wet-chemistry components accessible while phosphate and phosphorus results, diagnostics and method controls remain available through the interface.
Touchscreen
Clear access to phosphate and phosphorus results, status and analyser functions.
Data logging
Integrated phosphate and phosphorus result storage with USB export.
Separate compartments
Electronic and wet-chemistry sections are physically separated.
Low reagent use
Small reagent volumes help control phosphate and phosphorus measurement costs.
