Eutech DO 6+ Dissolved Oxygen Handheld Meter

  • DO Measurement Range Dissolved oxygen measurement range from 0 to 20.00 mg/l or ppm
Product Options


The Eutech DO 6+ offers supreme high performance whilst being user friendly, this no frills meter comes with user flexibility enabling the user to toggle between various modes from ppm, mg/l to % saturation, view electrode diagnosis etc. Accuracy is ensured under varying temperature conditions thanks to automatic temperature compensation (ATC) plus salinity and barometric pressure are automatically compensated after manual input for increased accuracy. Easy calibration can be performed at 100% and/or 0% and mg/l or ppm against a known solution.

For ease of use the DO 6+ has a galvanic cell which enables instantaneous measurements producing quick responses and eliminating polarisation resulting in minimal maintenance.

Features of the DO 6+ which make it so user friendly are the hold function which automatically freezes readings for easy viewing, comprehensive self diagnostic messages for easy troubleshooting and a large custom LCD providing optimum viewing even at a distance. Functional features of the DO 6+ are the auto-power off feature which saves battery power after non use, a protective rubber boot which shields the meter from accidental knocks and features a sturdy built in stand.

This product comes with an optional rugged carrying case which provides handy on site meter calibration and measurement.
