Dissolved oxygen (DO) is a liquid process measurement for determining the amount of oxygen dissolved or carried in the process liquid. There are three common technologies for dissolved oxygen measurements: polographic, galvanic and optical. The standard units of measure are milligrams per liter (mg/l), parts per million (ppm), parts per billion (ppb), or % saturation.……



4-Wire Analyzer DO402G

Flexibility, reliability and low maintenance are among the benefits provided by the EXA DO402G dissolved oxygen converter. Designed to meet the exacting requirements of measuring dissolved oxygen in the modern industrial environment, it contains many features to ensure the best precision whatever the application. The DO402G accepts inputs from both galvanic and polarographic sensors. Percent saturation, mg oxygen/l water, and ppm DO can be displayed and transmitted. Compensation for atmospheric pressure altitude, salinity and temperature are included for the best accuracy of measurement.
