RCYAGO Portable Dissolved Oxygen and Temperature Meter, DO Range: 0-40.00 mg/L, 0.1 mg//L Resolution, Digital Dissolved Oxygen Meter with Electrode Filling Fluid (No Backlight)
- ... oxygen and temperature. The dissolved oxygen probe is a thin film with a polarographic sensor and a thermistor for temperature measurement and temperature compensation. The permeable membrane separates the measured solution from the sensing electrode but allows oxygen to pass through the membrane to react, and the concentration can be measured..
- Dissolved oxygen refers to the concentration of molecular oxygen dissolved in water, generally expressed in mg/L (ppm) and saturation percentage (%), which is the percentage of dissolved oxygen in 1L of water. The oxygen concentration of our dissolved oxygen meter is 0.0-40.0mg/L, most of the range of dissolved oxygen meters on the market is 0.0-20mg/L. When measuring and calibrating, needn't open the protective cover of the electrode, just put the electrode in the solution for measurement..
- Detachable probe, easy to replace, equipped with 6 probe protective covers. The film inside the protective cover cannot be taken apart. After using for a period of time, the test value is inaccurate and the calibration is still inaccurate, and the membrane sleeve needs to be replaced..

Check StockDissolved Oxygen Meter,Portable Oxygen Meter Range:0-40mg/L,Dissolved Oxygen Test Kit with Electrode Filling Fluid,Aquarium Water Test Kit
- The oxygen meter is used to measure the dissolved oxygen content in aqueous solution, and the dissolved oxygen concentration is usually expressed in mg/L (dissolved oxygen per liter of water) or ppm (one millionth).Dissolved oxygen test kit on the market is 0.0-20mg/L,but our dissolved oxygen meter can test the value for 0.0- 40.0mg/L..
- Proper dissolved oxygen is essential for good water quality and all life forms require oxygen.If the oxygen monitor content in the water is lower than 5.0mg/L, it will be difficult for aquatic organisms to survive, and the lower the concentration, the more difficult it will be. If the oxygen meter content is lower than 1-2mg/L and lasts for several hours,it will lead to the death of a large number of aquatic organisms.So dissolved oxygen meter is very important for aquaculture,biological reactions,ponds..
