  • OxyGuard Atlantic Single Channel Dissolved Oxygen Meter Static System OxyGuard 24vDC

    OxyGuard OxyGuard Atlantic Single Channel Dissolved Oxygen Meter

    Atlantic measures oxygen and temperature in aquaculture systems. 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. Download Brochure
