OxyGuard Atlantic Single Channel Dissolved Oxygen Meter
The OxyGuard Atlantic is an accurate, reliable and easy to use oxygen meter with features ideal for use in aquaculture facilities such as shrimp farms, carp farms and other installations with individual, large ponds.
It measures both dissolved oxygen and temperature, and has 4 relay outputs. The dissolved oxygen measurement is compensated for atmospheric pressure, which permits accurate control of aerators. The user can link setpoints to parameters as desired. Setpoints can then be linked to output relays. It is also possible to link setpoints together. This permits, for example, an aerator to be started both from a DO setpoint and a temperature set point.

mg/L (ppm), % saturation and °C
Atlantic has a barometric pressure sensor, and the probe incorporates a temperature sensor. This gives you correct values of dissolved oxygen in both mg/L and % saturation.
Atlantic has 4 relay outputs and 8 set points. There will always be at least one relay output that can be used to give alarm if the oxygen level goes too low or the temperature too high. And since Atlantic measures both parameters and has logical linking you only need to use one relay.
Atlantic has 8 timers that can be used for a number of purposes. For example, alarm can be delayed so that only a sustained fault results in alarm being given.
The OxyGuard anti-fouling cap reduces membrane fouling significantly. Membrane fouling changes the sensitivity of the probe, and can otherwise be a problem in warm salt or brackish water.
Probe cleaner control
The OxyGuard probe cleaner uses compressed air, and has proved very effective. You can use a timer and relay in Atlantic to control the compressed air, and a second timer to “freeze” the output while cleaning.
Calibration with Atlantic is easy. Just wipe the membrane, place the probe in the air and start the process.
Aerator control saves energy
You can save energy by letting Atlantic control your aerators automatically. They will then only run when more oxygen is needed. If you also use aerators for temperature control you can logically link a temperature setpoint and a D.O. setpoint so that the aerator will run if the D.O. is too low or if the temperature is too high.
Link aeration and circulation
If surface D.O. levels are very high—above 100% sat—then it makes sense to start circulation propellers to send some of this oxygen-rich water to lower levels. Starting aerators would only blow the excess oxygen away. On the other hand, if D.O. levels are under 100%, then aeration is sensible.
Atlantic can control both propellers and aerators. For example by aerating to high D.O. levels when the water is cool and the D.O. less than 100% sat, then maintaining circulation when the water warms and the oxygen level is pushed over 100%
