Online Hydrazine Analyser
Support steam-cycle chemistry oversight with an application-specific online hydrazine method.
Online Hydrazine Analyser with 3S
Hydrazine monitoring is associated with suitable boiler-feed, condensate and steam-cycle water applications where treatment chemistry must be followed carefully. The 3S-CL performs a programmed wet-chemistry sequence and measures the resulting colour response online.
Low-level process measurements depend on sample integrity, temperature, expected concentration and the selected method. PMA reviews the sampling arrangement and operational objective before confirming whether a 3S configuration is appropriate. Explore the 3S-CL colorimetric analyser, review 3S applications or discuss sample preparation with PMA Support.
Repeatable online hydrazine measurement in a compact analyser
The programmed sequence handles the sample and reagents automatically, allowing operators to review hydrazine results and analyser status through the integrated touchscreen.
01 / HYDRAZINE METHOD
Parameter-specific hydrazine measurement
The configured 3S-CL runs a parameter-specific wet-chemistry sequence for hydrazine, 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 hydrazine monitoring between planned maintenance visits.
- Automatic calibration
- Automatic validation
- Automatic cleaning
Hydrazine analyser information
Core 3S-CL information for hydrazine 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 hydrazine monitoring
The 3S separates its electronic and wet compartments while keeping hydrazine results, analyser status and configuration accessible through the colour touchscreen.
Touchscreen
Review hydrazine 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.
