Online Cyanide Analyser
Configure cyanide analysis around the target form, sample matrix and site monitoring requirement.
Online Cyanide Analyser with 3S
Cyanide monitoring is relevant to selected industrial water and wastewater processes where regular analytical information is required. A 3S-CL configuration automates the defined sample-treatment and colorimetric measurement sequence for the chosen application.
Cyanide applications require careful method and sample review because the target form, matrix and handling conditions affect suitability. PMA assesses the expected concentration, process chemistry and sample delivery arrangement before recommending an online setup. Explore the 3S-CL colorimetric analyser, review 3S applications or discuss sample preparation with PMA Support.
Repeatable online cyanide measurement in a compact analyser
The programmed sequence handles the sample and reagents automatically, allowing operators to review cyanide results and analyser status through the integrated touchscreen.
01 / CYANIDE METHOD
Parameter-specific cyanide measurement
The configured 3S-CL runs a parameter-specific wet-chemistry sequence for cyanide, 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 cyanide monitoring between planned maintenance visits.
- Automatic calibration
- Automatic validation
- Automatic cleaning
Cyanide analyser information
Core 3S-CL information for cyanide 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 cyanide monitoring
The 3S separates its electronic and wet compartments while keeping cyanide results, analyser status and configuration accessible through the colour touchscreen.
Touchscreen
Review cyanide 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.
