Total Nitrogen Online Analyzer
AG-TN07 / AG-TN08 TN online analyzers for total nitrogen monitoring in nutrient removal and discharge projects.
Total Nitrogen Online Analyzer for environmental monitoring projects
AG-TN07 and AG-TN08 total nitrogen online water quality analyzers for nutrient removal and discharge monitoring projects.
AG-TN07 and AG-TN08 are selected for wastewater treatment, surface water, nutrient control and projects where total nitrogen is a required reporting parameter.
The TN analyzer supports a configurable 0-300 mg/L measuring range. Selection should confirm the expected TN level, sample matrix, digestion or conversion method, maintenance routine and whether the system will be integrated with COD, NH3-N and TP analyzers.
Technical data for model selection
Review the main measuring range, output interface, operating conditions and configuration notes before quotation.
Huisheng confirms the final model, range and site configuration according to sample condition and monitoring requirement.

Configured around the actual monitoring point
Nutrient analysis normally requires sampling, reaction or digestion and controlled measurement.
Wastewater, surface water, process water or water network points
Temperature, moisture, dust, solids, corrosive components or compound type may affect configuration.
Analyzer, detector, sampler, cabinet, pretreatment and data output can be combined as one product package.
Specifications are prepared according to the selected model and actual project requirement.
Details Huisheng reviews before confirming a model
Huisheng reviews the product model together with the measured medium, target range, sampling condition, installation position and required specifications. This keeps the product discussion tied to the real monitoring point.
Expected concentration or detection level helps determine the model and measurement method.
Temperature, moisture, suspended solids, dust, corrosion or target compound behavior may change the configuration.
Nutrient analysis normally requires sampling, reaction or digestion and controlled measurement.
Indoor cabinet, outdoor station, shelter or process-side installation depending on site
Communication output, alarm logic and model-specific specifications depend on the selected model.
Monitoring indicators covered by this product series
The final parameter package depends on the selected model, measuring range, sample condition and data output requirement. For many projects, one instrument is part of a complete monitoring point rather than a stand-alone purchase.

How the product fits into a complete monitoring chain
Most projects connect the product with sample access, conditioning, measurement, data acquisition and reporting. The exact arrangement depends on the site and selected model.
Sample intake and conditioning
The sample access point determines whether filtration, heating, flow control or preservation is required.
Digestion or conversion section
This part is configured according to the selected model and actual site conditions.
TN measurement module
This part is configured according to the selected model and actual site conditions.
Calibration and cleaning unit
This part is configured according to the selected model and actual site conditions.
Controller and data output
Data acquisition, alarm output and communication must match the project platform or reporting requirement.
Where this equipment is usually discussed
Water monitoring applications are selected by monitoring point first: discharge outlet, treatment process, river station, water network or industrial process water. The instrument scope then follows the parameter group, sample condition and cabinet arrangement.
Used where discharge quality, treatment stability or final outlet trends need to be followed with clearer online data.
Used where discharge quality, treatment stability or final outlet trends need to be followed with clearer online data.
Suitable for distributed water points where physical, nutrient or chemical indicators need continuous observation.
Used where discharge quality, treatment stability or final outlet trends need to be followed with clearer online data.
Configured according to the monitoring point, sample condition, installation environment and expected data use.
