    Extech DO210 Dissolved Oxygen Meter

    The Extech DO210 Dissolved Oxygen Meter is capable of measuring dissolved oxygen and water temperature. Dissolved oxygen can be measured in absolute terms from 0 to 20mg/l with accuracy of ±0.4mg/l or as a percentage of oxygen capacity from 0 to 100% with accuracy of ±0.7%. The temperature ranges goes from 0 to 50˚C with accuracy of ±0.8˚C.

    The Extech DO210 automatically compensates for temperature and the user can adjust for both altitude and salinity. A set of three push buttons is used to operate the oxygen meter and two readings can be shown simultaneously on the clear digital screen. Minimum/maximum recording and data hold are available with the oxygen meter.

    Readings are taken via the Extech DO210’s detachable DO probe which has an integrated sensor and is attached via a 1m cable. It has applications in industrial chemistry, water treatment, aquaculture and manufacturing. The meter is covered by a one-year warranty and is supplied with two spare replacement membranes, electrolytes, 9V battery and a soft case.
