Online Zinc Analyser
Configure online zinc analysis for the process matrix, expected range and treatment objective.
Online Zinc Analyser with 3S
Zinc measurement can support drinking-water, industrial water and wastewater applications where regular results help teams follow treatment or discharge conditions. The 3S-CL automates the selected reagent sequence and optical determination.
Other metals, sample colour, suspended material and process chemistry may affect the application. PMA reviews the expected zinc concentration and sample-conditioning needs before defining the analyser configuration. Explore the 3S-CL colorimetric analyser, review 3S applications or discuss sample preparation with PMA Support.
Repeatable online zinc measurement in a compact analyser
The programmed sequence handles the sample and reagents automatically, allowing operators to review zinc results and analyser status through the integrated touchscreen.
01 / ZINC METHOD
Parameter-specific zinc measurement
The configured 3S-CL runs a parameter-specific wet-chemistry sequence for zinc, 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 zinc monitoring between planned maintenance visits.
- Automatic calibration
- Automatic validation
- Automatic cleaning
Zinc analyser information
Core 3S-CL information for zinc 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 zinc monitoring
The 3S separates its electronic and wet compartments while keeping zinc results, analyser status and configuration accessible through the colour touchscreen.
Touchscreen
Review zinc 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.
