DISSOLVED OXYGEN IN WATER
Dissolved oxygen measurement is the measurement of oxygen gas (O2) dissolved in an aqueous solution. Dissolved oxygen is one of the most important parameters in aquatic systems. This gas is essential for the metabolism of aerobic organisms and also influences inorganic chemical reactions. Therefore, knowledge of the solubility and distribution dynamics of oxygen is essential for explaining both biological and chemical processes in water bodies. Oxygen enters water by diffusion from the surrounding air by aeration (rapid movement) and as a product of photosynthesis. The amount of oxygen (or any gas) that can be dissolved in pure water (saturation point) is inversely proportional to the temperature of the water; the warmer the water, the less dissolved oxygen.In aquaculture, dissolved oxygen is arguably the most important water quality parameter. Most species require a minimum concentration of 3 mg/L (ppm) of dissolved oxygen, but concentrations of 8–10 mg/L (ppm) are more appropriate. Unlike other gases such as nitrogen, supersaturated oxygen does not usually cause gas bubble disease (“Popeye”), so high levels of dissolved oxygen are generally not dangerous.
MODERN FEATURES OF METER
Step-by-Step On-Screen Instructions
Setup, calibration and measurement instructions with step-by-step instructions and on-screen animations.
Simply access Guidance Mode at any stage during setup or measurement using the dedicated HELP key.
AUTOMATIC DATA RECORDING
No need to worry as the photometer will automatically record the last 50 measurements.
Results can be viewed immediately using the Log Recall Menu.
CAL CheckTM
CAL Check FeatureTM Hanna's direct, simple procedure to ensure the photometer is working properly.
Simply insert the cuvettes containing Hanna standards into the meter and follow the instructions.
(HI97732-11 purchased separately)
Light Emitting Diode (LED) lamps provide more light but use less energy and generate less heat.
Narrow band interference filtering results in more accurate measurement results and higher repeatability.
A concave focusing lens reduces errors from imperfections in the cuvette.
High durability
Designed to withstand shock and water, the new IP67 body ensures top performance in any environment. The internal optical system prevents dust, dirt and water from entering. This photometer uses a proprietary positioning system that ensures the cuvettes are placed in the holder in the same position for accurate measurements every time.
Compact design
Designed to fit comfortably in your hand for on-the-go or tabletop use, the LCD display provides quick readings from any angle, day or night. The battery provides over 800 measurements.
The machine has calibration and accuracy testing functions.
CAL Check FeatureTM Hanna's direct, simple procedure to ensure the photometer is working properly.
Simply insert the cuvettes containing Hanna standards into the meter and follow the instructions.
