Thermo Scientific 4-STAR PH/DISSOLVED OXYGEN BENCHTOP METER

The rugged meter features enhanced stability indicators, salinity correction and automatic barometric pressure compensation and offers a full complement of GLP-related features?including available 21 CFR Part 11 software option.

Selectable 1 to 5 point pH calibration ensures accuracy even at extremes of concentration; dissolved oxygen calibration to the Winkler Titration improves accuracy by direct measurement of O2 concentration rather than inferring the concentration from temperature and pressure. SMART STABILITY^TM and SMART AVERAGING^TM functions simplify the measurement process. You can record and store up to 10 setup parameters and calibrations.
