product key technologies

This Benchtop Dissolved Oxygen Meter is a precision analytical instrument dedicated to laboratory and water quality detection. It is mainly used for the accurate determination of dissolved oxygen content in various aqueous solutions, meeting routine testing demands in scientific research, environmental monitoring, industrial water treatment, aquaculture and other industries.
Dissolved oxygen in water is an important physical and chemical indicator for water quality evaluation with multiple sources. In nature, oxygen in the atmosphere dissolves into water through natural gas-liquid interface permeation. Water flow, air convection and other dynamic airflow effects can further accelerate the oxygen dissolution rate. Meanwhile, oxygen released by aquatic plants and plankton during photosynthesis continuously supplements dissolved oxygen in water, forming the main supply sources of dissolved oxygen in natural water bodies.
This benchtop dissolved oxygen meter features stable and reliable performance, high detection sensitivity and excellent measurement repeatability. Adopting a stable bench-top structure, it is suitable for long-term fixed placement in laboratories, ideal for daily batch water sample testing and routine water quality monitoring.
With simple and user-friendly operation logic, it requires no complicated debugging and allows quick start-up. The instrument can rapidly and accurately capture real-time dissolved oxygen values of water samples, providing accurate and reliable data support for water quality assessment, process regulation and ecological water maintenance. It is an essential conventional physical and chemical analytical instrument for laboratories and testing institutions.
