The OxyGuard Salinity Probe is specially designed for aquaculture use. Factory calibration and automatic temperature compensation make it very easy to use. It is found in two versions. One is a 3-wire 4-20 mA sensor – connect it to 24 VDC and the output varies between 4 and 20 mA according to the salinity. The other has data bus connection for use with OxyGuard Pacific.
The probe is designed to be as trouble-free as possible, with features specially suited for aquacultural use. Inductive technology is used so that you don’t have to worry about deposits on the surface of the probe – all you have to do is ensure that the hole in the probe is open and relatively clean.
The probe measures salinity according to the internationally agreed PSS-78 scale (Practical Salinity Scale 78).
The OxyGuard Standard Probe – the probe that revolutionised oxygen monitoring.
The probe that you can purchase today is even better than the probe introduced in 1987 that helped revolutionize fish farming and make modern aquaculture the industry it is today.Today’s OxyGuard Standard Probe is hermetically sealed. If needed you can open it to replace the membrane and renovate it completely, but this should not be needed for many years.
The measurement stability of the OxyGuard Standard Probe is also very high indeed. A probe measuring in air will maintain accuracy even when subjected to a sudden 20 degree celcius temperature change. The sensitivity of a probe measuring in clean air at room temperature will remain the same for at least 3 years. This proves that the OxyGuard probe is not, like some other probes, affected by “ageing”.
OxyGuard believe that the OxyGuard Standard probe is more accurate, needs less attention and maintenance and has a lower total cost of ownership than any other oxygen or dissolved oxygen probe offered to the aquaculture industry today.
*Accessories are shipped with every OxyGuard probe. You will thus be able to change the membrane if you manage to damage it during installation. Otherwise the accessories can be enough for up to 5 years’ use.
OxyGuard temperature probes are robust, accurate and easy to use. They are filled with a special compound that protects against moisture. As standard the probes are fitted with 7 m cable, but they can be supplied with other lengths on request. The sensor in both types of probe consists of a stainless steel cylinder containing the thermistor or Pt100 element. This sensor tip is fitted to a black plastic housing. Standard types of housing are shown overleaf, but others can be supplied on request, e.g. to fit other pipe threads or fittings.
The OxyGuard TGP probe measures Total dissolved Gas Pressure and is designedspecifically for use with OxyGuard Commander or Pacific systems. It can be addedto existing systems. It contains sensors for dissolved gas pressure and temperature.The gases dissolved in water consist of oxygen and “other gases”. “Other gases” aremainly nitrogen. It is important to measure if the water is supersaturated in order toprevent the fish from getting gas bubble disease.
The Commander or Pacific system to which the probe is connected uses a dissolvedoxygen measurement made by a DO probe placed near the TGP probe forcalculations and presents the degrees of saturation for the total gas, dissolvedoxygen and for “other gas”.

Numerous aerator comparison tests show that paddle wheel aerators have the highest oxygen transfer per kWh. The easy-to-understand reason for this is that paddle wheel aerators create a directed flow and distribute the enriched water in the body of water. The renewed aeration of pond water that has just been aerated, as is unavoidable with some other types of aerators, is excluded. PWA paddle wheel aerators are in use in thousands of fish farms and shrimp farms around the world. In Europe, these devices are mostly used in fish farms and larger bodies of water (lakes, ponds).Advantages:- effective oxygen enrichment (O2)- degassing (CO2) with high fish stock- flow generation and distribution of the enriched water in the body of water- uncloggable- excellent price/performance ratio- maintenance and repair (if necessary) on site- very long service life (10 years of continuous operation and longer have been reported)Due to the intensive flow generation, these devices are only conditional suitable for small or medium-sized ponds. Even for the smallest devices with 0.49 kW (P2), the body of water should not be smaller than 500 m². If the water is too small or too shallow, there is a risk of embankments being flushed out and sludge being stirred up. The devices are only conditionally suitable for winter use.It is delivered as a kit with assembly instructions. Please note that devices with three-phase motors must be commissioned by a specialist. It is strongly recommended to only operate the device in connectionwith an appropriate motor protection. Please note that operating the device without a motor protection switch will void the motor warranty.
