Overview

GAOTek Dissolved Oxygen Meter with High Accuracy (Hold Function) is designed to measure DO of the liquids in the range of 0.00 mg/L~20.00 mg/L. Its auto-hold function freezes stable reading for easy viewing and recording. Manual salinity and barometric pressure compensations improve the accuracy of measurement. The meter’s system menu allows setting the 9 parameters, including the concentration unit, resolution, number of calibration points, stability condition, etc. This instrument is suitable for research and education, water and wastewater treatment and other industrial applications.
