Dissolved Oxygen Test Kits measure the oxygen levels in water, essential for aquatic life. These kits typically include reagents and color charts for quick analysis. They are used in environmental monitoring, aquaculture, and wastewater treatment.

Size: Typically 10-30 mL vial or bottle

Grade: Analytical or reagent grade

Viscosity: Liquid reagents with low to moderate viscosity

Buoyancy: Not applicable (liquid reagents in stationary containers)

Material: Glass or plastic vials, chemical reagents (e.g., indigo carmine, azide-modified Winkler reagents)

Measurement Range: 0-20 mg/L or 0-200% saturation

Accuracy: ±0.1-0.5 mg/L depending on method

Resolution: 0.1 mg/L or 1% saturation

Storage: Cool, dry place (some reagents require refrigeration)

Shelf Life: 6 months to 2 years (varies by reagent)

Test Method: Colorimetric, titration, or electrochemical

Temperature Range: 0-50°C (compensation may be required)

Reagent Stability: Light-sensitive (may require amber bottles)

Interferences: Avoid strong oxidizers, sulfides, or high turbidity
