Feature:1. Dissolved oxygen detector, with waterproof housing, converts signal of aqueous solution into a standard 485 signal after digital setting and analysis.2. It can measure dissolved oxygen, saturation, oxygen partial pressure and temperature in water with high accuracy and is not affected by flow rate.3. Effectively avoid the water plants hanging on the device to confirm the accuracy of the measurement.4. The prefabricated thread is more convenient for installation and fixation, the double‑standard prefabrication can meet different needs.5. Fluorescence probe, does not consume oxygen, is not interfered by magnetic field, has high sensitivity, and can continuously monitor online.6. Excellent performance, continuous monitoring data is connected to the recorder through the transmission output to achieve remote monitoring and recording.7. It can also be connected to RS485 interface, which can be easily connected to the computer to realize monitoring and recording.8. Widely used in aquaculture, sewage treatment, environmental monitoring, fish pond, factories, chemical fertilizers, metallurgy, pharmaceuticals, biochemicals, etc.Specification:Item Type: Dissolved Oxygen MeterMaterial: ABSWeight: Approx. 432g / 15.2ozMeasuring Principle: Fluorescence MethodRange: 10-20MG/L (-200% Saturation)Resolution 0.01MGL, 0.1℃Accuracy: ±2%FS.±0.5℃Temperature Compensation: Automatic Temperature Compensation (P1000)Output Mode: RS-485 BusWorking Conditions: 0-45℃, <02MPAStorage Temperature: 5-65℃Installation Method: Immersion InstallationPower Consumption: <0.5WPower Supply: 12-24VDC±10%Protection Level: IP68Calibration: Two-Point Calibration.Package List:1 x Dissolved Oxygen MeterNote:Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
