Online Total Phosphorus Analyser
Apply a configured preparation and colorimetric sequence to total phosphorus monitoring.
Online Total Phosphorus Analyser with 3S
Total phosphorus monitoring is relevant to suitable wastewater, surface-water and treatment applications where a broader phosphorus determination is needed. The 3S-CL can be configured to automate the required preparation, reaction and optical measurement sequence.
Total phosphorus is different from orthophosphate and may require additional sample treatment. PMA reviews the required determination, expected concentration, solids loading and sample preparation before confirming suitability. Explore the 3S-CL colorimetric analyser, review 3S applications or discuss sample preparation with PMA Support.
Repeatable online total phosphorus measurement in a compact analyser
The programmed sequence handles the sample and reagents automatically, allowing operators to review total phosphorus results and analyser status through the integrated touchscreen.
01 / TOTAL PHOSPHORUS METHOD
Parameter-specific total phosphorus measurement
The configured 3S-CL runs a parameter-specific wet-chemistry sequence for total phosphorus, with the exact chemistry and range selected for the sample and monitoring objective.
- Parameter-specific wet-chemistry sequence
- Freely programmable analysis frequency
- Automatic result calculation
02 / AUTOMATIC ROUTINES
Calibration, validation and cleaning
Automatic routines can be scheduled at selectable intervals to support repeatable total phosphorus monitoring between planned maintenance visits.
- Automatic calibration
- Automatic validation
- Automatic cleaning
Total phosphorus analyser information
Core 3S-CL information for total phosphorus method and installation review. The final chemistry, range and sample arrangement should be confirmed for the application.
Flexible installation
Wall or rack mounting is supported in the standard vertical arrangement.
Defined sample handling
A pressure-free sample reservoir presents flow to the analyser.
Process integration
Analog outputs and Modbus RTU RS485 support plant integration.
Operator records
The integrated datalogger supports USB result export.
Designed for practical total phosphorus monitoring
The 3S separates its electronic and wet compartments while keeping total phosphorus results, analyser status and configuration accessible through the colour touchscreen.
Touchscreen
Review total phosphorus results, status information and analyser functions.
Automatic routines
Calibration, validation and cleaning run at selectable intervals.
Separate compartments
Electronic and wet-chemistry sections are physically separated.
Low reagent use
Reagent consumption is confirmed for the selected chemistry and programmed analysis frequency.
