Online Chloride Analyser
Bring repeatable chloride analysis closer to the process with a configured 3S-CL method.
Online Chloride Analyser with 3S
Online chloride measurement can help operators follow changes in water treatment, boiler and condensate systems, cooling-water circuits and suitable industrial process streams. The 3S-CL automates the programmed sample and reagent sequence before measuring the resulting optical response.
Chloride chemistry and range are selected for the application rather than treated as a universal setup. Expected concentration, potential interferences and sample condition should therefore be reviewed with PMA before the analyser and any filtration arrangement are specified. Explore the 3S-CL colorimetric analyser, review 3S applications or discuss sample preparation with PMA Support.
Repeatable online chloride measurement in a compact analyser
The programmed sequence handles the sample and reagents automatically, allowing operators to review chloride results and analyser status through the integrated touchscreen.
01 / CHLORIDE METHOD
Parameter-specific chloride measurement
The configured 3S-CL runs a parameter-specific wet-chemistry sequence for chloride, 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 chloride monitoring between planned maintenance visits.
- Automatic calibration
- Automatic validation
- Automatic cleaning
Chloride analyser information
Core 3S-CL information for chloride 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 chloride monitoring
The 3S separates its electronic and wet compartments while keeping chloride results, analyser status and configuration accessible through the colour touchscreen.
Touchscreen
Review chloride 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.
