The RDO® sensor and analyzer is intended for the determination of dissolved oxygen in water. It is ideal for use in wastewater aeration basins and ponds. The sensor can be calibrated either against a referee instrument or in water-saturated air. Air calibration is completely automatic.

• SINGLE OR DUAL INPUT ANALYZER
• OXYGEN SENSOR uses the fluorescence quenching method
• ACCURATE READINGS: ±0.1 ppm between 0.0 and 8.0 ppm
