Dissolved Oxygen

Dissolved oxygen (DO) describes the amount of oxygen dissolved in water and is a key indicator of the health of aquatic habitats. Fish, plants, and microorganisms depend on adequate oxygen levels, typically between 7 and 11 mg/L, below 5 mg/L conditions become critical for many aquatic organisms.

When choosing a device, it is worth considering the sensor technology: polarographic sensors require regular electrolyte and membrane replacement, while optical sensors need less maintenance and last longer.
