Online Iron Analyser
Use parameter-specific colorimetric analysis to follow iron through suitable water-treatment processes.
Online Iron Analyser with 3S
Iron measurement can support drinking-water production, surface-water assessment, wastewater treatment and industrial process monitoring. The 3S-CL automates sample treatment and optical measurement using chemistry selected for the required iron determination.
See how Drinking-Water Metals Monitoring can help define the sample and operational question.
Dissolved, particulate and total measurement objectives can require different sample preparation, so the intended result must be defined clearly. PMA reviews filtration, digestion or other conditioning needs as part of the application assessment. Explore the 3S-CL colorimetric analyser, review 3S applications or discuss sample preparation with PMA Support.
Repeatable online iron measurement in a compact analyser
The programmed sequence handles the sample and reagents automatically, allowing operators to review iron results and analyser status through the integrated touchscreen.
01 / IRON METHOD
Parameter-specific iron measurement
The configured 3S-CL runs a parameter-specific wet-chemistry sequence for iron, 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 iron monitoring between planned maintenance visits.
- Automatic calibration
- Automatic validation
- Automatic cleaning
Iron analyser information
Core 3S-CL information for iron 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 iron monitoring
The 3S separates its electronic and wet compartments while keeping iron results, analyser status and configuration accessible through the colour touchscreen.
Touchscreen
Review iron 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.
