MGG/KL-DCB series of electromagnetic velocity meter is the portable measuring instrument of velocity and flow, which is professional designed for agricultural irrigation, hydrologic monitoring, rivers flow monitoring, municipal water, industrial sewage and etc. Low-power consumption and fully digital signal processing technology to make the instrument be more stable and reliable, measurement range be wider, accuracy be higher. And measuring accuracy will not be influenced by the high silt content in medium, large number of suspended solids, medium temperature and viscosity.

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. when measuring and calibrating, needn't open the protective cover of the electrode, just put the electrode in the solution for measurement. Blue tooth dissolved oxygen meter is supported by YINMIK mobile application, with accurate real-time blue tooth data transmission and clear measured values. allows you to save, manage, and share test data at any time without worrying about data loss. 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. Digital dissolved oxygen meter fully customizable parameter settings. set do max or min limit values according to the user's requirement. If testing results are out of range, the digits will display in red, notifying you of any values exceeding your preset range. Adopts the digital screen display with backlight, multi-parameter display at the same time, mobile phone App control backlight display. If it is not used, it will shut down automatically after 10 minutes. oxygen solubility will be affected by temperature, atmospheric pressure, and salinity. our instrument with temperature compensation can meet normal use.
