µAI 9060 SERIES

Dissolved Oxygen Analyzer

THIS PRODUCT IS DISCONTINUED and has been replaced with our NEW Dissolved Oxygen Analyzer Aqualyzer® 9061.

The Waltron µAI Series 9060 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 in the power (fossil, nuclear and cogeneration), desalination and petrochemical industry.

 
µAI 9060 Series Dissolved Oxygen Analyzer

 
AUTOMATIC CALIBRATION   DISPOSABLE DO SENSOR

The autocalibration is achieved by draining the flow cell and exposing the probe to air. This is carried out automatically on-line for three minutes and involves no manual operation. An automatic calibration check is performed every 7 days. Calibration can be initiated at any time manually by depressing the Manual Calibration Pushbutton on the instrument panel.

µAI 9060 Liquid Handling System

 

The Liquid Handling System features an air-tight flow cell housing a disposable solid state no maintenance DO sensor. The flow cell is self cleaning, preventing air bubble entrapment and minimizing particle deposition. The sensor is a galvanic membrane covered three electrode electrochemical cell. The sensor can be easily unscrewed from its holder, discarded, and replaced, an operation taking less than 60 sec. to perform.

µAI 9060 Disposable DO Sensor
