Dissolved Oxygen / BOD

Shop our selection of highly accurate and simple to use portable dissolved oxygen meters. Hanna's portable dissolved oxygen meters boast an excellent value due to their comprehensive range of features and afforability.
HANNA dissolved oxygen meters are made to accommodate the user, whether research grade laboratory instrumentation is necessary, or rugged, portable meters for use out in the field. Our DO meters utilize one of the two common types of dissolved oxygen sensing probes: polarographic sensors and galvanic sensors.
 

What is Dissolved Oxygen (DO)?

Dissolved oxygen analysis measures the amount of gaseous oxygen (O2) dissolved in an aqueous solution.

How Does Dissolved Oxygen get into water?

Oxygen gets into water by diffusion from the surrounding air, by aeration (rapid movement), and as a waste product of photosynthesis.

How Do I perform DO (Dissolved Oxygen) tests?

When performing the dissolved oxygen test, only grab samples should be used, and the analysis should be performed immediately. Therefore, this is a field test that should be performed on site.

Why is it important to measure dissolved oxygen?

Adequate dissolved oxygen is necessary for good water quality. Oxygen is a necessary element to all forms of life.
