Polarographic portable dissolved oxygen meter is a portable device designed based on electrochemical principle (polarography) and used to quickly measure dissolved oxygen (DO) concentration in water. With its high efficiency and reliability, it has become a key tool for water quality management and is widely used in environmental protection, aquaculture, industry and scientific research, helping sustainable resource utilization and ecological protection.
1. 3.7” Color screen, user-friendly interface.
2. Electrode adopts combination diaphragm cap, convenient to use. Each DO electrode equips with three spare diaphragms caps and one bottle of DO inner solution.
3. Data logging up to 3000 groups.
4. Air compensation: automatic.
5. Temp compensation: automatic.
6. Equipped with a USB Type-C charging port, conforms with the EU new law.
7. Ideal for use in harsh environments — IP57 Waterproof rating, silicone socket protector and grip cover protect the instrument from general impact.
8. Foldable stand allows use as a benchtop meter.
