Dissolved oxygen meter, detachable probe, digital display sensor for aquarium experiments, backlight-free operation

Features: 1. Oxygen and Temperature: This dissolved oxygen meter can be used to measure dissolved oxygen and temperature. The built-in microcomputer processor calculates and compensates all measurement data related to dissolved oxygen and temperature.2. Removable probe: This dissolved oxygen sensor adopts a removable probe, easy to replace, equipped with 6 probe protection covers.3. Digital Screen Display: This dissolved oxygen tester adopts digital screen display, which is clearer and more convenient to read the data. Supports auto power off in 8 minutes if you don't use it.4. Temperature compensation: Oxygen solubility will be affected by temperature, atmospheric pressure and salinity. Our instrument with temperature compensation can meet normal use.5.Wide Application: This dissolved oxygen meter is widely used in aquariums, swimming pools, ponds, freshwater aquaculture, marine aquaculture, school teaching experiments, sterile laboratory environments, aquaculture, scientific research, and other fields.Specifications:Item Type: Dissolved Oxygen Meter Material: ABS Application: Suitable for freshwater aquaculture, marine aquaculture, swimming pools, beverage factories, wastewater treatment plants, and laboratories.When the product leaves the factory, there is electrolyte in the membrane unit, which can be used directly.2. Connect the electrode, press the power button, turn it on, the screen will display the temperature in mg/L3. Briefly press the Mode button to switch between mg/L or %4. Briefly press the Hold button to lock the value, press the Temp button to switch between °C or °F5. Press the Cal button to calibrate in air, the screen will display 100.0% and calibration is successful once the flashing stops. If calibrated in deoxygenated water, it will display 0.0%Package List: 1 x Dissolved Oxygen Meter (battery not included) 1 x Dissolved Oxygen Membrane Group 6
