Product Description


DO-980 precision dissolved oxygen meter are used to measure amount of gaseous oxygen dissolved in a liquids.
1. Precision laboratory dissolved oxygen meter is equipped with a large backlit LCD.
2. 1 or 2 points calibration using the air-saturated water or zero oxygen solution.
3. Salinity and barometric pressure compensations ensure the reliable measuring results.
4. Automatic Temperature Compensation provides accurate reading over the entire range.
5. Calibration Due Alarm prompts user to calibrate the meter regularly.
6. Stability indicator shows when a measurement is recognized as stable.
7. Auto-Hold feature senses and locks the measurement endpoint.
8. Setup menu allows setting the 9 parameters, including the number of calibration points, resolution, stability criteria, auto-power off, etc.
9. Reset feature automatically resumes all settings back to factory default options.
10. Expanded memory stores and recalls up to 500 data sets.
11. Stored readings can be transferred into the computer by USB communication interface.
