Portable Nitrate and Nitrite Testing
Carry out rapid nutrient checks in field or laboratory work and use the results to direct wider water-quality investigations.
What does nitrate and nitrite show?
Nitrate and nitrite are nitrogen species found in natural waters, wastewater and treated supplies. Portable photometry can provide timely screening and trend information when the correct test method, reagents and measuring range are chosen.
Read the USGS overview of nitrogen and water for authoritative background. Return to our portable water-quality parameters guide to compare other measurements, or visit PMA for wider water and wastewater instrumentation support.
Where portable nitrate and nitrite testing is useful
Plan nutrient checks
Confirm which nutrient you need to measure, or whether your investigation requires both. Choose repeatable river, treatment-stage or discharge sampling points. Tell us the expected range, sample type and reporting units before selecting the reagent methods. Note unusual sample conditions and include the supporting measurements needed for the investigation.
Portable instruments for nitrate and nitrite
The correct instrument depends on the measurement method, expected range, water matrix, other parameters and how results need to be recorded.
MD 610 multiparameter photometer
A connected multiparameter photometer for reagent-based nitrate or nitrite methods and a wider water-testing programme.
Best for: teams needing flexible nutrient testing, stored results and field-to-office transfer.

Check the application before selecting
Tell us the sample type, expected range, test frequency, site conditions and how the result will be used. We will confirm the method, instrument configuration and supporting items before quotation.
What to include in your enquiry
- The sampling points and water or sludge type.
- The expected result range and reporting units.
- How often you test and which other measurements you need.
- The instrument or laboratory method used for comparison.
Share an example of your current test record and any practical constraints at the sampling point. This helps us review the complete workflow, including preparation, verification, accessories and result handling.
Keep nitrate and nitrite distinct
Confirm which nutrient you need to measure, or whether your investigation requires both. Tell us the expected range, sample type and reporting units before selecting the reagent methods.

Not sure which nitrate and nitrite option fits?
Tell us what water you are testing, the expected range, where the measurement will be made and which other parameters matter.
Portable nitrate and nitrite testing FAQs
What does portable nitrate and nitrite testing show?
Nitrate and nitrite are nitrogen species found in natural waters, wastewater and treated supplies. Portable photometry can provide timely screening and trend information when the correct test method, reagents and measuring range are chosen.
Where is portable nitrate and nitrite testing useful?
Common uses include river and catchment nutrient surveys, wastewater process and effluent checks, agricultural runoff investigations, raw-water and treatment monitoring. The best sampling point should always be chosen around the decision the result needs to support.
Which portable instrument can measure nitrate and nitrite?
MD 610 multiparameter photometer is the current Portable Analyser option shown for this parameter. Its suitability still depends on the method, range and sample.
Can a portable result help verify an online analyser?
Yes. A carefully collected portable result can provide an independent spot check during commissioning or investigation. Sampling location, timing, preparation and method differences must be considered before comparing readings.
What information should I provide before requesting a quote?
Share the water type, expected range, sampling location, testing frequency, other required parameters, record-keeping needs and any site constraints. This helps PMA confirm the complete practical package.
Can PMA help select the correct method and equipment?
Yes. PMA can review the application, expected conditions, measurement method, reagents or sensors, calibration needs and supporting accessories before quotation.
