Online Hydrazine Analyser
Monitor hydrazine in boiler and power-plant water chemistry using automated online analysis.
Online Hydrazine Analyser with AccuSeries
AccuSeries can be configured for hydrazine measurement in suitable boiler-water and power-generation applications. The analytical range, sample temperature, conditioning and method are reviewed to support reliable oxygen-scavenger control. Review PMA’s AccuSeries overview for wider product and application context.
Every configuration is application-specific. Confirm the analyte, expected range, sample composition, temperature, suspended solids, number of streams and required outputs with PMA before selection. Explore the AccuSeries online wet chemistry analyser and its water and process applications.
Programmable online hydrazine analysis
AccuSeries automates sample handling, method execution, result calculation and reporting for configured hydrazine measurement while operators monitor status through the graphical interface.
01 / CONFIGURED METHOD
A method matched to hydrazine and the process
Each analyser is configured around hydrazine, the required range, sample matrix and recognised analytical method.
- Approved method for hydrazine
- Configured range and sample matrix
- Method-specific hydrazine result calculation
02 / AUTOMATIC OPERATION
Sampling, calibration and cleaning
Programmable routines support repeatable hydrazine measurement while diagnostics and alarms alert users to changing analyser or process conditions.
- Automatic sampling
- Automatic calibration
- Automatic cleaning
A controlled hydrazine measurement sequence
Each hydrazine result follows a configured sampling, reagent, measurement, calculation and maintenance sequence.
01.
Capture the sample
The internal fast loop and sample mechanism provide a representative, consistent sample volume for hydrazine analysis.
02.
Add method reagents
The programmed sequence doses the reagents required for the selected hydrazine method.
03.
Run the configured method
The approved hydrazine method proceeds under controlled conditions.
04.
Calculate the hydrazine result
The measured response is converted into the configured hydrazine concentration result.
05.
Calibrate
Automatic calibration can run against configured hydrazine standards at selected intervals.
06.
Clean
Automatic cleaning supports the hydrazine measurement system between planned maintenance visits.
Designed for practical hydrazine monitoring
The modular AccuSeries design keeps wet-chemistry components accessible while hydrazine results, diagnostics and method controls remain available through the interface.
Touchscreen
Clear access to hydrazine results, status and analyser functions.
Data logging
Integrated hydrazine result storage with USB export.
Separate compartments
Electronic and wet-chemistry sections are physically separated.
Low reagent use
Small reagent volumes help control hydrazine measurement costs.
Hydrazine technical specifications
Core AccuSeries information for hydrazine application and specification review.
