The Polaris C Optical meter is an almost maintenance free meter for measuring dissolved oxygen and temperature. The meter is sturdy, easy to use and has an extensive longevity making it ideal for harsh conditions.
Polaris C can store up to 2500 complete set of data, including time and date stamps. The logged data can be stored either manually or automatically with the possibility to group the data into categories. The stored data can be uploaded directly to Cobália using Bluetooth.
Scan the Cobália NFC tag on the tank and all data will be uploaded to your “digital farm”. Tank specific data assigned to the tags will be stored in Cobália for analysis on temporal variation, generation of graphs and for multivariable analysis on performance. The meter has a built-in self-check of all hardware, it compensates automatically for barometric pressure and it has a notably short response time. With this meter, you get the high-quality associated with OxyGuard technology and a product that will serve you well for many years.

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 Handy Salinity is a hand-held instrument specially designed for aquaculture use. Factory calibration and automatic temperature compensation make it very easy to use. The display shows the salinity directly. Temperature is also measured and shown in the display.
The instrument incorporates automatic check functions to ensure reliability. 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.
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.

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!

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.
