Hanna Photometer Marine Multiparameter

HI97105 combines several essential marine photometric tests in one portable instrument. It measures light transmitted through a reagent-treated water sample and displays the concentration directly in the selected parameter’s unit.

The meter is suitable for advanced reef aquarists, coral farms, aquarium shops, maintenance services and other applications requiring consistent marine-water testing.

Measurement methods

• Marine pH: 6.3–8.6
• Marine alkalinity: 0.0–20.0 dKH
• Marine calcium: 200–600 mg/l
• Marine nitrate LR: 0.00–5.00 mg/l NO₃
• Marine nitrate HR: 0.0–75.0 mg/l NO₃
• Marine nitrite ULR: 0–200 ppb NO₂-N
• Marine phosphate ULR: 0.00–0.90 mg/l PO₄

Directions

1. Select the required measurement method.
2. Rinse a clean cuvette with the sample.
3. Add the exact sample volume required by the method.
4. Clean the outside of the cuvette.
5. Insert the untreated sample and perform the zero reading.
6. Add the correct method-specific reagents.
7. Mix exactly as instructed on the display.
8. Use the built-in reaction timer.
9. Remove air bubbles and clean the cuvette again.
10. Reinsert the cuvette in the same orientation.
11. Perform the final reading.
12. Record or recall the stored result.
13. Clean all reusable testing equipment after use.
14. Never return a treated sample to the aquarium.
