Hanna HI764103 Digital dissolved oxygen probe
The Hanna HI764103 Digital dissolved oxygen probe is a high-performance digital dissolved oxygen (DO) probe designed for advanced water quality monitoring. It delivers precise DO measurements in both % saturation and ppm (mg/L), while also supporting integrated atmospheric pressure compensation. Ideal for demanding applications in environmental monitoring, aquaculture, wastewater treatment, and research laboratories, this probe features smart digital calibration, excellent resolution, and reliable accuracy across an extended measurement range.
Key Features
Wide Measurement Range: Accurately measures DO from 0.0 to 500.0% saturation or 0.00 to 50.00 ppm (mg/L) to cover both standard and high-oxygen environments.
High Accuracy and Resolution: Offers resolution down to 0.1% or 0.01 ppm and industry-grade accuracy suitable for professional and regulatory applications.
Smart Automatic Calibration: One or two-point calibration at 0%, 100%, or a user-defined value for enhanced ease of use and reproducibility.
Atmospheric Pressure Compensation: Integrated pressure measurement and correction ensures data stability across changing barometric conditions.
Digital Communication: The digital output enables seamless integration with compatible meters and reduces electrical noise, improving data integrity.
Rugged and Reliable Design: Built for both laboratory and field use, with robust components to withstand tough environmental conditions.
