1. Equipped with a built-in cleaning brush for automatic probe cleaning, keeping the probe clean and maintenance-free;
2. Optical dissolved oxygen membrane head, maintenance-free compared to membrane methods, requiring no periodic electrolyte replenishment;
3. Fast reaction time, data stabilizes within 10-15 seconds after power-on;
4. Thick, wear-resistant membrane head with a lifespan of up to 3 years, particularly suitable for harsh environments such as aquaculture and wastewater treatment, and supports secondary membrane head replacement;
5. Simultaneously outputs dissolved oxygen, temperature, and saturation values;
6. Supports atmospheric pressure and salinity compensation, usable in areas with varying altitudes and salinity levels, ensuring accuracy;
7. Supports secondary calibration to maintain data accuracy.
