The Water dissolved oxygen velocimeter developed and designed by our company uses the latest digital integrated circuit technology and international detection technology to design a new smart handheld tester. The Water dissolved oxygen velocimeter uses a large full-color LCD screen to display readings in real time. At the same time, the detection circuit designed by the international well-known manufacturers digital chips can achieve extremely high sensitivity and excellent repeatability. The shell is made of industrial special high strength composite plastic, high strength, feel good. The detector can be widely used in environmental protection, factories, water plants, sewage treatment, aquaculture and other fields.
