Dissolved Oxygen Meter

Dissolved Oxygen Meter
TEII - Wastewater Depot - Catalog Index - Dissolved Oxygen Meter

The TEII Dissolved Oxygen Fluoroprobe together with the Fluorometer controller is designed to provide long-term monitoring and control of appropriate devices based on the saturation level of oxygen in gaseous or aqueous solutions. The standard unit comes with a contact for aerator control.

Dissolved Oxygen Meter Dissolved Oxygen Sensor

Dependable - The TEII-DO Dissolved Oxygen Meter can be used for long-term monitoring of oxygen levels without the necessity of changing the membrane or electrolyte fluids. The TEII-DO unit uses optics instead of the other methods which make the TEII-DO more reliable.

Easy To Use - Does not require repetitive calibration and/or compensation for membrane effects which are an extremely large source of error and drift for any probe using membrane/electrolyte and dissimilar metal anodes and cathodes (galvanic and "Clark probe").

Reliable - The maintenance requirement for continued long-term utilization is to wipe off the sensor when necessary.

Versatile - Can be configured to control aeration of wastewater operations, aqua culture applications and process control.

Economical - The Fluoroprobe together with the Fluorometer controller can be provided at a cost which normally will be recovered by cost savings of power consumption.

Aeration Control - TEII-DO1 has a standard contact closure for aeration operation based on a high/low setting on the controller.

Available Options:

4-20ma Current Analog or 0-10V Voltage Output of the Real DO Value
Remote control via Analog signal of the High/Low contact closure values
Integrated Remote Control and Monitoring of DO and Aeration
