The Bluetooth dissolved oxygen meter supports mobile applications, with real-time and accurate transmission of Bluetooth data. The measured values of the aquarium water testing kit are clear at a glance. Allow you to save, manage, and share test data at any time. The digital display dissolved oxygen meter adopts a mobile app to control the backlight digital display. The digital display of the colorimeter is clearer and easier to read. The dissolved oxygen detection kit can customize its own parameters. The oxygen meter will automatically turn off when not in use for about 8 minutes and has a low battery alarm function. Measurement range of dissolved oxygen meter: dissolved oxygen: 0.0-30mg/L, dissolved oxygen saturation: 0.0-300.0%, temperature: 0.1-40.0 C; 32.0-104.0F. The automatic temperature compensation of the dissolved oxygen meter makes the dissolved oxygen test more stable. If the oxygen monitor content in water is below 5.0mg/L, aquatic organisms will find it difficult to survive. If the content of the dissolved oxygen monitor is below 1-2mg/L and lasts for several hours, it will lead to the death of a large number of aquatic organisms. Therefore, oxygen monitors or dissolved oxygen detection kits are very important for aquaculture, biological reactions, and ponds. The dissolved oxygen detection kit can be used to measure and monitor the oxygen content that affects reaction rate, process efficiency, or the environment. Such as aquariums, swimming pools, teaching experiments, laboratory sterile environments, scientific research, environmental testing (lakes, streams, oceans), wastewater treatment, wine production, etc. Color: Black material: plastic Package Contents: 1 x Oxygen Meter Only the above package content, other products are not included.
