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.

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.
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 Handy Polaris TGP (Total Gas Pressure) Meter is a hand-held gas pressure meter that doubles as a dissolved oxygen meter. It can operate in three display modes- as a standard Handy Polaris dissolved oxygen (DO) meter, as a TGP meter displaying percent saturation, or as a TGP meter displaying pressures as volume percentage values. The user can choose which value is shown on the display.
DescriptionThe instrument also incorporates a data logger. Menu functions, along with an intuitive interface, make the Handy Polaris TGP/DO/Temperature meter easy to use for novice and experienced users alike. The OxyGuard Handy Polaris TGP/DO/Temperature Meter also includes a membrane kit (10 O-rings/10 membranes), 50 ml electrolyte, membrane installation tool, and cathode cleaning pad.
Technical AdvantagesMeter The Polaris 2 TGP is designed for easy use and to give accurate here-and-now measurements of both the dissolved oxygen and the dissolved rest gases - i.e. the gases that can cause decompression sickness - “the bends” - in fish. This is achieved because the instrument measures all three pressures needed - the dissolved oxygen, the total dissolved gas and the atmospheric. Maintenance is easy - the DO measurement is made using the well-known OxyGuard Handy probe, and the TGP measurement tube sensor element can easily be exchanged if necessary. Probe The OxyGuard TGP probe can be directly connected to OxyGuard Commander, Convoy and Pacific systems. It can only be used with these systems. It does not need a separate transmitter or input unit, but communicates values directly. Only one field bus data cable connection is needed - the cable has cores for both data and the 24 V DC supply needed by the probe. The TGP is designed for easy use. The measurement tube is wound on a central bobbin that is held in place by the protector. If the tube becomes fouled you simply unscrew the protector, unplug the bobbin and tube and fit a replacement. Precise measurements are obtained by placing the TGP in the air and matching - or calibrating - the TGP against the barometric pressure sensor of the DO Meter or Pacific of the system. This means that a very accurate value of the difference between the gas pressure in the water and the gas pressure in the air can be obtained. The pressure measurements can also both be calibrated against the absolute value of the barometric pressure if this is known accurately. The TGP has the same diameter as a standard OxyGuard probe so that standard mounting devices can be used.

The Model 420 is a membrane covered galvanic oxygen probe with built-in two-wire 4-20 mA transmitter. The probe is connected to a DC supply and draws a current of between 4 and 20 mA corresponding to the oxygen concentration.There are only two wires to connect, and there is no limit to cable length. The output signal is galvanically isolated from the built-in electronics and the process fluid. Interference between the Model 420 and other equipment can never occur!
