Online Copper Analyser
Use automated colorimetric analysis to follow copper where frequent process information is needed.

Online Copper Analyser with 3S
Online copper analysis can support drinking-water treatment, wastewater management and industrial process control where regular results help teams understand changing conditions. The 3S-CL carries out a programmed colorimetric sequence and records the resulting measurement for operator review.
The applicable chemistry depends on concentration, sample composition and the purpose of the measurement. Potential interferences, sample presentation and any filtration requirement should be considered as part of the application review rather than after installation. Explore the 3S-CL colorimetric analyser, review 3S applications or discuss sample preparation with PMA Support.
Repeatable online copper measurement in a compact analyser
The programmed sequence handles the sample and reagents automatically, allowing operators to review copper results and analyser status through the integrated touchscreen.
01 / COPPER METHOD
Parameter-specific copper measurement
The configured 3S-CL runs a parameter-specific wet-chemistry sequence for copper, 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 copper monitoring between planned maintenance visits.
- Automatic calibration
- Automatic validation
- Automatic cleaning
Copper analyser information
Core 3S-CL information for copper 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 copper monitoring
The 3S separates its electronic and wet compartments while keeping copper results, analyser status and configuration accessible through the colour touchscreen.
Touchscreen
Review copper 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.
