ST8406 Portable Split High Precision Dissolved Oxygen Meter Water Quality Testing for Fish Pond Aquaculture

Introduction:
- The molecular oxygen dissolved in air in water is called dissolved oxygen, abbreviated as DO, which is an important indicator for detecting water quality. Widely used in aquaculture, biological reactions, environmental testing, water/wastewater treatment, laboratory fields, medical fields, and many other fields.
- High precision split type probe, basic error: ±0.4mg/L, adopting a split type design for more convenient measurement.
- One click storage, no need to copy; Up to 1999 data records can be recorded, and data recording/viewing can be easily accessed with just one click, making it convenient and worry free.
- Upgrade imported smart chips to be over 50% faster than traditional old-fashioned chips.
- Triple compensation, precise and rigorous measurement; The content of dissolved oxygen is closely related to temperature, salinity, and atmospheric pressure. Automatic temperature compensation is 0-40℃, manual salinity compensation is 0-45‰, and atmospheric pressure compensation is 101.3-79.9KPa or 760-600mmHg.
- High definition large screen LCD backlit display, easy to cope with various environments, and can clearly view values even in dark and strong light environments.
- Built-in lithium battery, supports charging function, can be fully charged in 4 hours.
- Automatic shutdown, energy-saving: If there is no operation for 5 minutes, the instrument will automatically shut down.

Details:
- Anti breakage design: anti pulling and anti breakage protection interface, extending the lifespan of the probe.
- Probe anti-collision cap: wear armor on the sensor to prevent damage to the probe from daily collisions.
- Back battery compartment: equipped with 3.7V rechargeable lithium batteries.
- Anti slip design of the body: ergonomic design, one handed grip for comfortable anti slip.
