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)

  • Dissolved oxygen meter is a precision instrument for measuring dissolved 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..
  • Adopts the digital screen display, which is more clear and convenien....
