1.Product Introduction:

JPB—607AThe portable dissolved oxygen analyzer is mainly designed for the convenience of users to carry and is suitable for on-site and field operations. It can display both dissolved oxygen and temperature values simultaneously. This instrument is suitable for measuring dissolved oxygen in water sources, aquaculture farms, environmental protection, sewage treatment plants, beverage industry, and scientific research institutions.
