Extech DO210 Compact Dissolved Oxygen Meter
The Extech DO210 Compact Dissolved Oxygen Meter is a portable digital instrument designed to measure dissolved oxygen and temperature. It measures dissolved oxygen concentration from 0 to 20.0 mg/L and oxygen saturation from 0 to 100.0%. The meter also measures temperature from 0 to 50°C, making it suitable for water testing, industrial chemistry, water treatment, aquaculture and manufacturing applications.
With automatic temperature compensation, the Extech DO210 Compact Dissolved Oxygen Meter adjusts for temperature changes through a sensor built into its polarographic oxygen probe. Users can also adjust the meter for salinity and altitude to suit different measurement conditions. Its dual digital display shows two readings at the same time, while three push-button controls provide a straightforward way to operate the instrument. Data hold and minimum/maximum recording functions help users retain readings and review measurement values during testing.
For convenient measurements, the instrument uses a detachable dissolved oxygen probe with an integrated temperature sensor and a 1 m cable. The Extech DO210 Compact Dissolved Oxygen Meter comes with two spare replacement membranes and electrolyte to support probe maintenance. A 9V battery powers the meter, and the included soft case provides a practical way to carry and store the instrument. Its compact design makes it a useful choice for routine dissolved oxygen and temperature measurements.
