What You Gain: 1*Instrument, 9.84 ft SD02 dissolved oxygen electrode, 30mL electrolyte, spare membrane head + rubber ring, sandpaper, USB charging cable and user manual.

How to install the dissolved oxygen electrode correctly?
Rinse and dry the electrode and membrane head with pure water. Fill the head 3/4 full with electrolyte and screw it tight. Remove spilled electrolyte and check for air bubbles. Reinstall the head if bubbles are present.
Does the instrument need calibration before first use?
The zero-oxygen calibration is completed at the factory. For daily use, only full-scale calibration in air or oxygen-saturated water is required.
What types of calibration are supported?
This DO meter supports three calibration modes: zero-oxygen calibration, full-scale calibration and temperature calibration, which can meet different accuracy requirements.
What core compensation functions does this device have?
Built with comprehensive compensation functions including auto temperature, manual air pressure and salinity compensation. It works stably across environments and guarantees accurate measurement in diverse water bodies.
When do I need to set atmospheric pressure and salinity?
The default pressure is 101.3 KPa. Adjust it to match local air pressure for better accuracy. Set the salinity level accordingly when testing seawater or saline water to ensure valid compensation.
