Industrial Online Dissolved Oxygen Analyzer DO Oxygen in Water Controller
>>Overview
The industrial online dissolved oxygen analyzer is a
microprocessor-based water quality online monitoring and control
instrument. Equipped with polarographic dissolved oxygen electrodes
or fluorescence dissolved oxygen sensors, this instrument is widely
used across various industries including power plants,
petrochemicals, metallurgy, electronics, mining, paper
manufacturing, bio-fermentation, pharmaceuticals, food & beverage,
environmental water treatment, and aquaculture. It provides
continuous monitoring and control of dissolved oxygen levels and
temperature values in aqueous solutions.
