  • OxyGuard Salinity Probe Probe OxyGuard 4-20mA

    OxyGuard OxyGuard Salinity Probe

    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). IO1 OxyGuard Salinity Probe (4-2mA) / (Pacific)

  • Oxygen Pacific LDO Oxygen Probe Probe OxyGuard

    OxyGuard Oxygen Pacific LDO Oxygen Probe

    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 Technical Data Sheet

  • The OxyGuard Oxygen Probe Probe OxyGuard For 840

    OxyGuard The OxyGuard Oxygen Probe

    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. DescriptionThe 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 Celsius 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. D02 OxyGuard Oxygen Probe

  • OxyGuard Model 420 Dissolved Oxygen Probe Probe OxyGuard 4-20mA = 0-40mg/l (Super Saturated Water)

    OxyGuard OxyGuard Model 420 Dissolved Oxygen Probe

    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!

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! The OxyGuard Model 420 can therefore be connected directly to a wide range of equipment that can accept a 4-20 mA input, such as alarms, indicators, controllers, recorders, PLC’s, PC systems with A/D input etc. The Model 420 can also be used to measure gaseous oxygen concentration Key BenefitsExtremely High Stability -zero adjustment is never needed, calibration seldom No regular maintenance needs. The robust membrane is easily cleaned, but if damaged can be easily replaced Correct measurements with flow as low as 1cm/s Based on a chemical principle superior to that of traditional DO probes Galvanic type - True Zero Built0in temperature compensation No practical limit to cable length Wide range of armatures and fixtures - e.g. the AirAlam for worker safety in areas where fluctuating oxygen levels could occur in the air D033 OxyGuard Model 420 DO Probe for 4-20mA

  • Last stock! Oxyguard pH / Redox Probe Probe OxyGuard pH Flow Through Light Duty

    OxyGuard Oxyguard pH / Redox Probe

    These OxyGuard probes consist of an electrode and an impedance converter inside a two part 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 light duty or heavy duty OxyGuard pH or redox electrodes with flange fittings can be used. 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. K01 OxyGuard Static pH / Redox Probe

  • Last stock! OxyGuard Total Gas Pressure TGP Probe Probe OxyGuard

    OxyGuard OxyGuard Total Gas Pressure TGP Probe

    The OxyGuard TGP probe measures Total dissolved Gas Pressure and is designed specifically for use with OxyGuard Commander or Pacific systems. It can be added to existing systems. It contains sensors for dissolved gas pressure and temperature.  The gases dissolved in water consist of oxygen and “other gases”. “Other gases” are mainly nitrogen. It is important to measure if the water is supersaturated in order to prevent the fish from getting gas bubble disease. The Commander or Pacific system to which the probe is connected uses a dissolved oxygen measurement made by a DO probe placed near the TGP probe for calculations and presents the degrees of saturation for the total gas, dissolved oxygen and for other gasses.

  • Last stock! OxyGuard Temperature Probe Probe OxyGuard Standard (D061)

    OxyGuard OxyGuard Temperature Probe

    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. Technical Data D06 OxyGuard Temperature Probe
