Online dissolved oxygen sensor
Description of Online dissolved oxygen sensor:
XY - 4000 Online dissolved oxygen sensor with microprocessor monitoring instrument online of water quality. The instrument configuration of the different types of dissolved oxygen electrode is widely used in power plants, petrochemical industry, metallurgy, electronics, mining, paper, fermentation, pharmaceutical, food and beverage, environmental protection water treatment, aquaculture, and other industry. For continuous monitoring of dissolved oxygen (do) value of the aqueous solution and temperature and control.
