Waltron's 9065 Luminescent Dissolved Oxygen Analyzer is known for its ease of use, accuracy, and dependability. Coupled with the Sensor Exchange Program, it may be the last Dissolved Oxygen instrument you ever need to buy.

Each year a ready-to-use 9065 Luminescent Dissolved Oxygen sensor will arrive with a factory Certificate of Calibration and everything needed to replace your existing sensor -- plus an extended, one-year warranty to cover the entire instrument electronics and sensor.
