⚠️ Important Notes

Before measurement, please make sure batteries are correctly installed and fully charged.
Keep the sensor probe clean and dry during measurement. Avoid touching the probe with fingers.
Measure in a well‑ventilated environment to obtain accurate oxygen‑concentration readings.
Remove batteries if the instrument will not be used for a long time to prevent leakage‑induced damage.
Not waterproof. Do not immerse the unit in water or store it in high‑humidity environments.
