Online Formaldehyde Analyser
Bring automated formaldehyde measurement into process monitoring where the sample is suitable.
Online Formaldehyde Analyser with 3S
Online formaldehyde analysis can provide more frequent process information than intermittent manual checks in suitable industrial water streams. The 3S-CL controls sample handling, reagent addition, reaction timing and optical measurement within a programmed analytical cycle.
The final method depends on expected concentration, sample composition and the operational reason for monitoring. PMA reviews possible matrix effects and sample-conditioning needs before confirming the analyser configuration. Explore the 3S-CL colorimetric analyser, review 3S applications or discuss sample preparation with PMA Support.
Repeatable online formaldehyde measurement in a compact analyser
The programmed sequence handles the sample and reagents automatically, allowing operators to review formaldehyde results and analyser status through the integrated touchscreen.
01 / FORMALDEHYDE METHOD
Parameter-specific formaldehyde measurement
The configured 3S-CL runs a parameter-specific wet-chemistry sequence for formaldehyde, 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 formaldehyde monitoring between planned maintenance visits.
- Automatic calibration
- Automatic validation
- Automatic cleaning
Formaldehyde analyser information
Core 3S-CL information for formaldehyde 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 formaldehyde monitoring
The 3S separates its electronic and wet compartments while keeping formaldehyde results, analyser status and configuration accessible through the colour touchscreen.
Touchscreen
Review formaldehyde 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.
