2. It can measure dissolved oxygen (including pressure and salinity compensation) and temperature.
3. The parameters of the probe can be calibrated and single point calibration can be used.
4. Provide different display modes - dissolved oxygen (%), dissolved oxygen (ppm), and temperature (℃).
5. Provide a plastic calibration bottle filled with damp foam for calibration, transportation, and storage of probes. Storing probes in a damp environment will prolong their service life.
6. The power supply uses 9V batteries, which have a long battery life.
7. There will be sound feedback when using the buttons.
8. Provide a "LOBAT" (low power) display to remind users to replace the battery.
