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.

 

Key Benefits
  • Measure dissolved oxygen in water and oxygen percentage in air using one compact instrument.
  • Check water temperature alongside dissolved oxygen measurements without using a separate temperature meter.
  • Automatic temperature compensation adjusts measurements for temperature changes through the probe’s built-in sensor.
  • Adjustable salinity and altitude compensation lets users account for different testing conditions.
  • View two measurement readings at once on the clear dual digital display.
  • Capture the current reading with the data hold function for easier review.
  • Track minimum and maximum readings during testing to help identify changes in measured values.
  • Use the detachable probe and 1 m cable for convenient access during water testing.
  • Maintain the oxygen probe using the included replacement membranes and electrolyte.
  • Carry and store the meter, probe and accessories in the supplied soft case.

 

Common Applications

The Extech DO210 Compact Dissolved Oxygen Meter is suitable for a range of testing, maintenance and inspection tasks, including:

  • Dissolved oxygen measurement in water treatment applications.
  • Water temperature measurement during water treatment testing.
  • Dissolved oxygen monitoring in aquaculture applications.
  • Water temperature checks in aquaculture systems.
  • Dissolved oxygen testing in industrial chemistry applications.
  • Temperature measurement in industrial chemistry processes.
  • Dissolved oxygen measurement in manufacturing applications.
  • Oxygen percentage and air temperature measurements.

 

Why Choose This Model?

The Extech DO210 Compact Dissolved Oxygen Meter combines dissolved oxygen concentration, oxygen saturation and temperature measurement in one portable instrument. Its automatic temperature compensation, adjustable salinity and altitude settings, dual display and detachable probe make it a practical choice for routine water testing.
