DescriptionUsage Tips: The dissolved oxygen meter provides high-precision and accurate dissolved oxygen readings, delivering fast test results. This Bluetooth-enabled dissolved oxygen meter supports mobile applications for real-time and reliable data transmission.The aquarium water testing kit displays clear, easy-to-read measurements, allowing you to save, manage, and share test data anytime.The digital display dissolved oxygen meter works with a mobile app to control the backlight, offering a clearer and more readable display. The dissolved oxygen detection kit allows customization of user-defined parameters. The meter automatically powers off after approximately 8 minutes of inactivity and features a low battery warning.Measurement range: Dissolved oxygen: 0.030.0 mg/L; Dissolved oxygen saturation: 0.0300.0%; Temperature: 0.140.0C (32.0104.0F). The dissolved oxygen meter includes automatic temperature compensation for more stable and consistent test results.Low dissolved oxygen levels can be harmful to aquatic life. Levels below 5.0 mg/L may stress aquatic organisms, and prolonged exposure to levels of 12 mg/L can result in fatalities. Therefore, oxygen monitoring is essential in aquaculture, biological processes, and pond management.This dissolved oxygen detection kit is suitable for measuring and monitoring oxygen levels in various applications, including aquariums, swimming pools, educational experiments, laboratory sterile environments, scientific research, environmental testing (lakes, streams, oceans), wastewater treatment, and wine production.Color: Black Material: Plastic Package Contents: 1 x Oxygen Meter Note: Light reflection and differences in display screens may cause slight variations between the color shown in the image and the actual product.
