This is an economical benchtop dissolved oxygen meter for daily use in experiments to measure dissolved oxygen concentration in liquid samples. It is widely used in environmental monitoring, aquaculture and experimental research.
The measurement accuracy of 0.5mg/L can meet most of the experimental needs. In addition, salinity and atmospheric pressure are compensated to eliminate measurement errors.
Dissolved oxygen meter's sensor is susceptible and accurate.
Dissolved oxygen meter is calibrated with zero oxygen solution and air-saturated water to ensure calibration reliability.
Large memory capacity for easy retention of monitoring data
Menu support for customization
Automatic temperature compensation ensures accurate measurements over the entire measurement range.
