Portable Dissolved Oxygen Testing
Understand oxygen conditions at the sampling point and add immediate field evidence to wastewater, river and receiving-water investigations.
What does dissolved oxygen show?
Dissolved oxygen is the oxygen available in water to aquatic organisms and biological treatment processes. Portable measurement helps teams see conditions at a specific place and time, while temperature and sampling technique remain important to interpretation.
Read the USGS guide to dissolved oxygen 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 dissolved oxygen testing is useful
Portable instruments for dissolved oxygen
The correct instrument depends on the measurement method, expected range, water matrix, other parameters and how results need to be recorded.
Section 82 water-quality kit
A portable field package for dissolved oxygen and temperature together with pH, conductivity, turbidity and ammonia.
Best for: field teams that need oxygen conditions in the context of several supporting parameters.

Not sure which dissolved oxygen option fits?
Tell us what water you are testing, the expected range, where the measurement will be made and which other parameters matter.
Portable dissolved oxygen testing FAQs
What does portable dissolved oxygen testing show?
Dissolved oxygen is the oxygen available in water to aquatic organisms and biological treatment processes. Portable measurement helps teams see conditions at a specific place and time, while temperature and sampling technique remain important to interpretation.
Where is portable dissolved oxygen testing useful?
Common uses include aeration and wastewater process checks, river and receiving-water surveys, storm-overflow investigations, incident response and pollution screening. The best sampling point should always be chosen around the decision the result needs to support.
Which portable instrument can measure dissolved oxygen?
Section 82 water-quality kit 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.
