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.

The OxyGuard Commander probe is a membrane covered galvanic cell that generates an electrical signal proportional to the oxygen pressure it senses. The probe is designed for use in applications across the aquaculture industry and is capable of measuring oxygen in clean water, waste water, and air for ambient monitoring. It requires neither an applied voltage nor microprocessor controlled electronics in order to function.
Even in the most demanding aquaculture applications the OxyGuard Commander probe can keep its calibration for about a year and operate for three to five years before membrane replacement is needed.
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.
