Dissolved Oxygen Analyzer 

BHB provides a wide range of liquid analyzers using different analysis modules according to the characteristics of the liquids, the components you intend to analyse and the applications that they are designed for.

The Dissolved Oxygen Analyzer provides correct monitoring of the dissolved oxygen levels in sewage.

The sewage treatment is often hampered by fouling of the sensor with rags or other large solids present in the sample under test. These materials tend to become attached to the sensor and sensor holder giving rise to incorrect readings.

This problem is resolved by using the Floating Ball Dissolved Oxygen System which comprises a flat-ended sensor mounted into a relatively large diameter spherical flotation collar. This form of construction presents to the sample a surface on which it is difficult for rags and other large solids to lodge. For more demanding applications, on-line cleaning is available using the water wash option.

MEASURING PRINCIPLE:

• Oxygen electrochemical reaction.

COMMON APPLICATIONS:

• Drinking water treatment particularly in the determination of the quality of the treated water.

MEASURING PERFORMANCE:

• Response time – typically 20 seconds for 90% of a step-change of oxygen concentration at 20 ºC;
• Temperature compensation: Automatic correction by means of an integral Pt 100 resistance thermometer.
• Operating temperature: 0 to 40 ºC;
• Operating pressure: Atmospheric;
• Minimum liquid velocity: 30 cm/s;
• Accuracy: ± 0,2 mg/L or ± 2% saturation within ± 10 ºC of the calibration temperature in the range 0 to 35 ºC.
