Online Fluoride Analyser
AccuSeries provides automatic online fluoride measurement for drinking water, process water and wastewater. PMA reviews the required reporting range, sample chemistry, pH and potential interferences before selecting and configuring the measurement method.
Online Fluoride Analyser with AccuSeries
AccuSeries can use ion-selective electrode methods for fluoride measurement across suitable drinking-water, process-water and wastewater duties. The concentration range, ionic strength, sample preparation and interferences are reviewed for each application. Read PMA’s independent fluoride 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.
Fluoride ISE and SPADNS colorimetry
Galvanic documents two fluoride measurement routes: an ion-selective electrode with controlled sample conditions, or SPADNS colorimetry. Selection depends on the concentration range, sample matrix, interferences and the reference method used to verify the online result.
FLUORIDE METHOD OPTIONS
Control the sample chemistry before measurement
The fluoride ISE sequence uses an ionic-strength-adjusting buffer to control measurement conditions; standard known addition can be used in a configured low-range method. In SPADNS colorimetry, fluoride reduces the colour of a zirconium-dye reagent. The measured loss of colour is related to the fluoride concentration.
- Confirm the measuring range and the required fluoride reporting basis.
- Review pH, ionic strength, colour and known interfering constituents.
- Agree calibration standards, any dilution and comparison with the laboratory.
02 / AUTOMATIC OPERATION
Sampling, calibration and cleaning
Programmable routines support repeatable fluoride measurement while diagnostics and alarms alert users to changing analyser or process conditions.
- Automatic sampling
- Automatic calibration
- Automatic cleaning
A controlled fluoride measurement sequence
Each fluoride 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 fluoride analysis.
02.
Add method reagents
The programmed sequence doses the reagents required for the selected fluoride method.
03.
Run the configured method
The approved fluoride method proceeds under controlled conditions.
04.
Calculate the fluoride result
The measured response is converted into the configured fluoride concentration result.
05.
Calibrate
Automatic calibration can run against configured fluoride standards at selected intervals.
06.
Clean
Automatic cleaning supports the fluoride measurement system between planned maintenance visits.
Designed for practical fluoride monitoring
The modular AccuSeries design keeps wet-chemistry components accessible while fluoride results, diagnostics and method controls remain available through the interface.
Touchscreen
Clear access to fluoride results, status and analyser functions.
Data logging
Integrated fluoride result storage with USB export.
Separate compartments
Electronic and wet-chemistry sections are physically separated.
Low reagent use
Small reagent volumes help control fluoride measurement costs.
