Features

1. Practical design, excellent performance, suitable for laboratories and outdoor areas

2. Can measure the concentration and air saturation of mg/L, with accuracy up to ±0.03 mg/L or ±0.3% air saturation

3. The air saturation mode makes the calibration procedure quick and easy, eliminating the need to measure the probe temperature and atmospheric pressure, making measurements of liquids with unknown oxygen dissolution coefficient feasible.

4. The measurement range is wide, 0 to 20 mg/L or 0 to 200% air saturation, especially suitable for the measurement of 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. The LCD screen has a background light function, and can still read clearly in a dim environment.

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

9. Operate with a battery or AC power, the battery life is 1,000 hours (carbon zinc battery), and there is also a low battery display

10. Additional battery packs can be placed in the fuselage for outdoor agitators

11. Attached with a recorder output interface to connect to the icon recorder or other recording equipment
