The concentration of dissolved oxygen in aquatic settings, such as seas, rivers, pools, and groundwater, is measured using a portable instrument called the “Portable Dissolved Oxygen Meter” (Extech DO700 ). It measures the amount of dissolved oxygen in the water using an electrochemical sensor.
The 9-in-1 DO700 Kit also detects temperature, conductivity, TDS, salinity, pH, and mV in addition to DO concentration and saturation. For DO readings, it has both automated salinity correction and manual barometric pressure correction.
Additionally, it has automated temperature adaptation and simple one-button calibration of 4, 7, and 10 pH with the option of three-point calibration for greater precision. complete with batteries, durable carrying bag, pH and conductivity calibration solutions, polymer conductivity cell, pH/mV/Temp electrode, and DO probe.

The electrochemical sensor in this device measures the changes in electric voltage caused by the combination of oxygen and electrolyte in water using the electrodes it is equipped with.
This device is primarily used in a variety of sectors, including those that deal with water and sewage, chemicals, food, fisheries, aquaculture, the environment, and scientific research. Additionally, this apparatus is used in natural settings, such as in investigations into the chemical composition of water and how it affects aquatic habitats, in investigations into the growth and reproduction of fish and other aquatic animals, in investigations into aquatic ecosystems, and related investigations into environmental pollution and water quality.
