AWQ-DO Sensor for Dissolved Oxygen
Measuring dissolved oxygen in water, the OPTOD sensor uses an optical luminescence measurement principle.
With two versions, stainless steel and titanium, for different conditions.
The OPTOD stainless steel sensor is used for measurement of urban wastewater and industrial effluent treatment, as well as surface water monitoring.
The titanium version is designed for seawater and other corrosive environment.
Both versions share the same RS485 and SDI-12 signal output options, as well as the Aqualabo stored calibration data system enabling simple change over for maintenance purposes.
The AWQ-DO (Optical Dissolved Oxygen technology) is based on luminescent optical technology. The AWQ-DO sensor is in compliance with the ASTM International Method D888-05. AWQ-DO does not require calibration, and thanks to an ultra low power technology, the AWQ-DO sensor meets the demands of field work, short and long term installation. Without oxygen consumption, this technology allows you to accurate measure in all situations, especially in very low oxygen concentrations.
The AWQ-DO sensor stores calibration and history data within the sensor. This allows for a plug and play system without the need for re-calibration.
Thanks to Modbus RS485 and SDI-12, the AWQ-DO can be connected to most commonly used devices.
Compact, strong and light, the sensor can be used for portable measurement, or installed for fixed/permanent use.
