Online Phosphate Analyser
Support phosphate control and treatment optimisation with a parameter-specific online method.
Online Phosphate Analyser with 3S
Phosphate measurement can support drinking-water dosing, wastewater nutrient treatment, surface-water monitoring and selected industrial processes. The 3S-CL automates the configured colorimetric reaction so operators can follow phosphate behaviour at programmed intervals.
Orthophosphate and broader phosphorus determinations are not interchangeable. The target measurand, reporting basis, digestion requirement, range and sample condition must be agreed before configuration. Compare this method with the online total phosphorus analyser, read the orthophosphate versus total phosphorus guide, and review wastewater nutrient applications.
Repeatable online phosphate measurement in a compact analyser
The programmed sequence handles the sample and reagents automatically, allowing operators to review phosphate results and analyser status through the integrated touchscreen.
01 / PHOSPHATE METHOD
Parameter-specific phosphate measurement
The 3S-CL runs a phosphate-specific wet-chemistry sequence. The exact colorimetric chemistry and measuring range are selected around the required phosphate determination and sample matrix.
- 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 phosphate monitoring between planned maintenance visits.
- Automatic calibration
- Automatic validation
- Automatic cleaning
Phosphate analyser information
Core 3S-CL information for phosphate 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 phosphate dosing and treatment review
Programmed phosphate results can help teams review dosing, removal and changing process conditions. The analyser keeps its wet-chemistry and electronic compartments separate while providing result and status access through the touchscreen.
Touchscreen
Review phosphate 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.
