Product Features

1. Practical design, excellent performance, suitable for laboratory and field use

2. It can measure concentration in milligrams per liter and air saturation with an accuracy of up to ± 0.03 milligrams per liter or ± 0.3% air saturation

3. The air saturation mode makes the calibration process fast and simple, eliminating the need to measure probe temperature and atmospheric pressure, making it feasible to measure liquids with unknown oxygen solubility coefficients

4. Wide measurement range, 0 to 20 milligrams per liter or 0 to 200% air saturation, especially suitable for measuring supersaturated water samples

5. Automatic temperature compensation eliminates the effects of membrane permeability coefficient and oxygen solubility caused by changes in water temperature

6. Direct dial salinity input, compensation range 0 to 40ppt, including accurate temperature compensation, can directly read dissolved oxygen concentration in the ocean or estuary

7. LCD screen with background lighting function, can still read clearly in dim environments

8. The body shell is sealed and waterproof, and comes with a cover for recording output and power interface

9. Operated using batteries or AC power, with a battery life of 1000 hours (carbon zinc battery) and a low battery display

10. Additional battery packs can be placed inside the body for use with outdoor mixers

11. Comes with a recorder output interface for connecting icon recorders or other recording equipment
