Online Nickel Analyser
Configure nickel analysis for the concentration range and matrix found at the selected sample point.

Online Nickel Analyser with 3S
Nickel monitoring can support selected industrial process-water and wastewater applications where more frequent measurement helps operators track treatment or discharge conditions. The 3S-CL performs a repeatable programmed wet-chemistry cycle for the selected method.
Sample colour, suspended solids, other metals and process chemistry may influence the application review. PMA therefore considers the complete matrix and any pretreatment requirement before specifying the analyser setup. Explore the 3S-CL colorimetric analyser, review 3S applications or discuss sample preparation with PMA Support.
Repeatable online nickel measurement in a compact analyser
The programmed sequence handles the sample and reagents automatically, allowing operators to review nickel results and analyser status through the integrated touchscreen.
01 / NICKEL METHOD
Parameter-specific nickel measurement
The configured 3S-CL runs a parameter-specific wet-chemistry sequence for nickel, 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 nickel monitoring between planned maintenance visits.
- Automatic calibration
- Automatic validation
- Automatic cleaning
Nickel analyser information
Core 3S-CL information for nickel 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 nickel monitoring
The 3S separates its electronic and wet compartments while keeping nickel results, analyser status and configuration accessible through the colour touchscreen.
Touchscreen
Review nickel 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.
