SeaGuard O2 Recorder - SeaGuard O2-Fornitore globale

8th Floor, Building 2, East China Normal University Science and Technology Park, 1038 Jinshajiang Road, Shanghai, China

Andra Ocean Guardian O₂The recorder is a sturdy, durable, and powerful O developed based on the Ocean Guardian platform₂Recorder. It can be used for O₂Self capacitance measurement of concentration. At the same time, the instrument can also serve as a platform extension to add other measurement parameters such as CTD, ocean currents, turbidity, waves, and tides

characteristic:
· High resolution, low drift · Low maintenance volume · Principles of Optical Measurement · Long term stability · No calibration required for over a year · The measurement interval can be selected from 2 seconds to 2 hours · SeaGuard Studio visualization software · Intelligent sensor based on CANbus interface · Can be used for both seawater and freshwater

The Andra dissolved oxygen probe is based on the fluorescence quenching measurement principle of the lifecycle. It uses platinum porphyrin complex as the fluorescent material, embedded in a breathable fluorescent film, and a black light isolation coating protects the fluorescent material from the influence of sunlight and particle fluorescence in water. One side of the fluorescent film is exposed to the environmental water, and the other side is installed on the optical window of the measurement room. The fluorescence quenching measurement principle based on the lifecycle has the following advantages compared to electrochemical sensors: · The impact of disturbance is relatively small (does not consume oxygen) · Less affected by pollution · Measuring the absolute concentration of dissolved oxygen does not require frequent calibration · Better long-term stability · Less affected by pressure · The impact of pressure is predictable · Faster response time Ocean Guardian O₂The recorder can collect data through Andra real-time data acquisition software, and the output parameters can be displayed and processed through SeaGuard Studio software. The sensor is an intelligent sensor that is plug and play and can automatically recognize.

Technical Parameter

Note: (1) To obtain mg/L, divide by 31.25. (2) When the salinity change exceeds 1mS/cm, salinity compensation is required. (3) Calibration range: 0-120%. (4) Calibration range: 0-36 ° C. (5) Parameters are subject to change without prior notice.
