Extech DO700 Dissolved Oxygen Kit
The Extech DO700 Dissolved Oxygen Kit offers a practical way to test water quality in the field or laboratory. It measures dissolved oxygen, pH, mV, conductivity, total dissolved solids (TDS), salinity, resistivity and temperature using one portable meter. Its waterproof IP57 housing helps protect the unit during outdoor testing, while the compact design makes it easy to carry between locations. Users can measure several water quality parameters without needing a separate meter for each function.
Accurate testing relies on clear readings and simple calibration. The Extech DO700 Dissolved Oxygen Kit features three-point pH calibration and a one-button pH calibration function to make routine setup easier. It also recognises eight conductivity calibration standards from the USA, Europe and China. Automatic salinity and temperature compensation support dissolved oxygen testing, while manual barometric pressure adjustment gives users more control over measurements.
For regular testing, the Extech DO700 Dissolved Oxygen Kit combines data storage with simple controls and a clear display. Its dual backlit LCD makes readings easier to see in low light, while the internal memory stores up to 400 labelled readings with measurement values and temperature. Two AA batteries power the meter, and an automatic power-off function helps preserve battery life. A hard carrying case keeps the meter and its accessories organised during storage and transport.
Key Benefits
- Measure eight water quality parameters with one portable instrument, reducing the need to carry several meters.
- Use automatic salinity and temperature compensation to support consistent dissolved oxygen measurements.
- Complete routine pH setup quickly with one-button calibration and three-point calibration options.
- Work with eight recognised conductivity calibration standards from the USA, Europe and China.
- View readings clearly on the large dual backlit LCD, including during testing in poor lighting.
- Store up to 400 labelled readings with measured values and temperature for later reference.
- Use the waterproof IP57 housing for added protection during field testing and riverside monitoring.
- Adjust barometric pressure manually to suit dissolved oxygen measurement conditions.
- Reduce unnecessary battery use with the automatic power-off function, which can also be disabled.
- Keep the meter, probes and calibration accessories together in the supplied hard carrying case.
