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.

Marlin is a single-channel measurement transmitter instrument explicitly designed for use in aquaculture.
One of the critical advantages of Marlin is its water resistance, which means it can be used in various wet environments without fear of damage.
You can order Marlin with the probe of your choice to meet your specific needs:
Dissolved oxygen (electrochemical or optical)
Carbon Dioxide (CO2)
pH/Redox
Total Gas Pressure (TGP)
Temperature
Salinity
Ozone
Any other probe with 4-20 mA input (e.g. Model 420)
Compatibility:
Marlin features a 4-20mA output and MODBUS/TCP for PLC/SCADA compatibility, making integrating your existing systems easy.
It is also Cobália compatible, ensuring seamless communication with the Cobália digital management system.
Whether running a commercial aquaculture operation or simply monitoring the water quality in your backyard pond, Marlin is the perfect tool!

OxyGuards new optical oxygen probe is developed in cooperation with world leading experts. Based on luminescence quenching of a sensor dye immobilized on a support foil it can be used for gas measurements as well as for dissolved oxygen (DO).
The presence of molecular oxygen quenches the luminescence, changing its intensity and lifetime fully reversibly. The measurement principle is very robust. It shows virtually no interference to other gases and has very low drift. Bleaching is not an issue because low energy red light excites the sensor spot and emission is NIR.
Special features
High-accuracy measurements of oxygen in gas or water (DO)
Low drift
Long lifetime
Fast response
Digital output of all major oxygen units

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.

These OxyGuard probes consist of an electrode and an impedance converter inside a twopart housing held together by a threaded collar. There is extra sealing so that the connections at the top of the electrode remain dry even when the probe is completely submersed. The impedance converter immediately over the electrode eliminates electrical noise problems and permits the use of ordinary cable to connect the probe. Either lightduty or heavy duty OxyGuard pH or redox electrodes with flange fittings can be used.
As standard probes are manufactured from PVC (for temperatures up to 60°C), but on request they can be supplied in other materials, e.g. PP for up to 10 bar at 25 °C, 4 bar at 90 °C, or PVDF for up to 6 bar up to 100°C, 2 bar at 120°C.
There are three basic designs, one for free mounting, one with a 3/4″ tee for flow-through use, the third designed to be screwed into a pipe, flange or other suitable fixture. The probes can be ordered with a 1″ thread at the top of the top part for mounting purposes. OxyGuard also manufacture probes to customer specification, so please ask if you cannot use a standard design. As standard the probes have 7m cables.
For Heavy Duty use in very dirty environments probes can be supplied with a probe cleaning system. This has, for example, proved effective when measuring agricultural slurry – add “C” to ordering number. Several types of mounting device are also available. These are described in separate brochures.

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”.

OxyGuard's developed ozone sensor is designed specifically for use in aquaculture. The sensor uses an entirely new innovative technology, and the partial pressure of ozone is measured directly without the use of electrolyte, reagents, light, or other traditional methods. As a result, there is almost no maintenance, the probe is exceptionally stable, and the response time is extremely fast.With the possibility to measure ozone content in the water down to only a few μg/L, it is possible to ensure safe conditions for the stock.
Unit of Measurement: ppm (mg/l) Measuriing Range (Low): 0-0.8mg/l (best between 0 and 0.5) Mesauring Range (High): 0.5-8mg/l Operating Temperature: 0-40C Dimensions: 40 x 104mm Cable Legnth: 7m Response Time: 90% in less than 45s (for the low range type) Medium: Water Installation: For use with Pacific or Marlin
