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 Atmosphere is a hand-held meter designed to measure oxygen in gas. It can be used to measure the low oxygen content of packaging gas, the oxygen content of the air and the purity of oxygen gas from oxygen generators and the like.
DescriptionThe OxyGuard Handy Atmosphere is a hand-held meter designed to measure oxygen in gas. It can be used to measure the low oxygen content of packaging gas, the oxygen content of the air and the purity of oxygen gas from oxygen generators and the like. A separate brochure is found for a version designed to measure the oxygen content of the modified atmosphere inside food packages. Signal processing is performed using a microprocessor, which gives a number of advantages. Just as with other Handy instruments you can simply switch on and measure, but the use of microprocessor technology enables measurements to be supported by a range of advanced functions designed to make things even easier for you:
Features
Automatic Calibration
Choice of Language
Oxygen, temperature, barometric pressure.
Automatic self-check
Automatic Probe Check
Barometric Pressure Compensation
Extremely long battery life
Technical Data Sheet
H02A OxyGuard Handy Atmosphere
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.
