Online Nitrate Analyser
Measure nitrate in water, wastewater and industrial processes with configured automated wet chemistry.
Online Nitrate Analyser with AccuSeries
AccuSeries can be configured for online nitrate analysis where a reagent-based method is appropriate for the sample and range. Automated sampling and chemistry provide regular process data for treatment control and environmental monitoring. Read PMA’s independent nitrate application guide for wider measurement 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 nitrate analysis
AccuSeries automates sample handling, method execution, result calculation and reporting for configured nitrate measurement while operators monitor status through the graphical interface.
01 / CONFIGURED METHOD
A method matched to nitrate and the process
Each analyser is configured around nitrate, the required range, sample matrix and recognised analytical method.
- Approved method for nitrate
- Configured range and sample matrix
- Method-specific nitrate result calculation
02 / AUTOMATIC OPERATION
Sampling, calibration and cleaning
Programmable routines support repeatable nitrate measurement while diagnostics and alarms alert users to changing analyser or process conditions.
- Automatic sampling
- Automatic calibration
- Automatic cleaning
A controlled nitrate measurement sequence
Each nitrate 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 nitrate analysis.
02.
Add method reagents
The programmed sequence doses the reagents required for the selected nitrate method.
03.
Run the configured method
The approved nitrate method proceeds under controlled conditions.
04.
Calculate the nitrate result
The measured response is converted into the configured nitrate concentration result.
05.
Calibrate
Automatic calibration can run against configured nitrate standards at selected intervals.
06.
Clean
Automatic cleaning supports the nitrate measurement system between planned maintenance visits.
Designed for practical nitrate monitoring
The modular AccuSeries design keeps wet-chemistry components accessible while nitrate results, diagnostics and method controls remain available through the interface.
Touchscreen
Clear access to nitrate results, status and analyser functions.
Data logging
Integrated nitrate result storage with USB export.
Separate compartments
Electronic and wet-chemistry sections are physically separated.
Low reagent use
Small reagent volumes help control nitrate measurement costs.
Nitrate technical specifications
Core AccuSeries information for nitrate application and specification review.
| Measurement principle | Application-specific approved method |
| Variables | Nitrate, range and sample matrix dependent; approved method |
| Typical response | T-90 typically 3 to 15 minutes; method dependent |
| Power supply | 24 VDC or 90 to 240 VAC; 310 W |
| Sampling | Single stream or up to 6 streams |
| Cabinet | Painted 304 stainless steel |
| Protection grade | IP66; NEMA 4X |

Nitrate, range, sample conditions, wetted materials and final specifications must be confirmed for the configured method before procurement.
Discuss your nitrate measurement
Tell PMA about your sample, measuring range and process objective. An applications engineer will review whether AccuSeries and an available analytical method are appropriate.
