The DO9100 Dissolved Oxygen Meter represents a breakthrough in water analysis technology, engineered to deliver exceptional accuracy, reliability, and efficiency for professionals across environmental monitoring, aquaculture, wastewater treatment, and scientific research. This advanced instrument combines innovative sensor design with intelligent features to address the most demanding dissolved oxygen (DO) measurement challenges, ensuring optimal conditions for aquatic ecosystems, industrial processes, and regulatory compliance.

At the heart of the DO9100 lies a next-generation optical dissolved oxygen sensor, utilizing luminescence quenching technology to provide maintenance-free operation with unparalleled stability. Unlike traditional polarographic sensors, the optical system eliminates the need for electrolytes, membranes, and frequent calibrations, while resisting interference from flow rates, pH fluctuations, and other dissolved gases. The meter offers an extensive measurement range (0–60 mg/L and 0–600% saturation) with automatic compensation for temperature, salinity, and atmospheric pressure, ensuring data integrity across diverse applications—from pristine natural waters to harsh industrial effluents. A high-resolution color touchscreen displays real-time readings, graphical trends, and diagnostic metrics, while onboard memory stores up to 100,000 datasets with GPS and timestamp logging. Wireless connectivity (Bluetooth and Wi-Fi) enables seamless integration with mobile devices and cloud platforms for remote monitoring, data sharing, and advanced analysis.

Built to excel in the most challenging environments, the DO9100 features an IP68-rated waterproof and dustproof housing, a shock-resistant design, and an intuitive interface optimized for gloved-hand operation. Its long-lasting rechargeable battery supports extended fieldwork, and customizable alarms notify users of critical DO thresholds for proactive intervention. The device also supports multi-parameter expansion, allowing simultaneous measurement of pH, ORP, conductivity, and temperature with optional sensors. By merging cutting-edge optical technology, rugged durability, and seamless data management, the DO9100 sets a new standard for dissolved oxygen meters, empowering professionals to achieve new levels of precision and productivity in water quality management.
