Hanna HI97732 Dissolved Oxygen Photometer
Measure a prepared water sample using a reagent method
The HI97732 measures dissolved oxygen in a collected water sample over 0.0–10.0mg/L as O2. It uses an azide-modified Winkler method and a photometer to read the prepared sample.
Choose it if a chemical sample-test procedure suits your work. It is not a probe that you lower into the pond for an immediate live oxygen reading, and it is different from a dashboard showing calculated oxygen potential.

Sampling matters
The manufacturer procedure begins with a completely filled 60mL glass bottle and avoids trapped air. The sample is treated in the specified sequence before a portion is measured in a cuvette. Follow that procedure rather than treating it as an ordinary dip test.
Air bubbles and changes during sample handling can affect oxygen results. Use the correct bottle, reagent quantities and timing from the manual. The on-screen tutorial helps guide the sequence, but it does not remove the need for careful sample collection.
What to allow for
The specified reagent sets are HI93732-01 for 100 tests or HI93732-03 for 300 tests. Check that you have the required sample bottle and preparation equipment as well as the meter and cuvettes.
The standard HI97732 base package includes two sample cuvettes with caps/stoppers, three AA batteries and documentation. Test reagents and matched CAL Check standards are separate requirements. The named standard set is HI97732-11.
Use CAL Check mode and the supplied certificate for performance verification and any permitted user calibration. A reference cuvette and the chemicals used to prepare a water sample have different roles.
A measured result or a calculated display?
The oxygen-potential display associated with a Seneye Pond monitoring pack is calculated, rather than a direct measurement of the oxygen in the pond. This Hanna method measures a prepared sample, while a suitable oxygen probe offers a different measurement process.
Compare the method, range and practical sampling routine before choosing. Our water-testing range includes other parameters, instruments and sample-test approaches.
