Waltron Dissolved Oxygen Analyzer in Water

Add to wishlist

The Waltron AQUALYZER® 9061 Dissolved Oxygen Analyzer is a state-of-the-art microprocessor-based instrumentation package developed specifically for use in measuring low and high concentrations of dissolved oxygen. It is today’s standard for all low range dissolved oxygen analyzers.

True Fully Automatic Calibration
Calibration is carried out automatically online and involves no manual operation.An automatic calibration check is performed at a predetermined frequency by the instrument; however, calibration can be initiated at any time manually if needed.
