Product Introduction：

Dissolved Oxygen (DO) refers to molecular oxygen dissolved in water, typically expressed as milligrams of oxygen per liter of water (mg/L). It serves as a crucial indicator for measuring the self-purification capacity of water bodies and is also one of the key factors essential for the survival and reproduction of aquatic organisms.

Product Application：

Biopharmaceuticals, sewage treatment, aquaculture, fermentation engineering, food and beverage, iron and steel smelting
