  • OxyGuard Aquaculture Monitoring Probe

  • OxyGuard - Model DO - Oxygen Probe

    OxyGuard - Model DO - 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.

  • OxyGuard - Ocean Probe

    OxyGuard - Ocean Probe

    This small-size version of the standard OxyGuard dissolved oxygen probe is a membrane-covered galvanic cell that generates its own voltage. The Ocean DO Probe is designed for long-term measurements in ponds, lakes and oceans at depths up to 2000 m. A special version for depths up to 7000 m is available on request.

  • OxyGuard - Model 525 / 505 - Probes

    OxyGuard - Model 525 / 505 - Probes

    These probes have built-in transmitters and are powered by low voltage supplies. They are intended for environmental monitoring. The 525 has a Standard Probe type sensor and will operate with a supply voltage as low as 5.5 V. Its output signal is 0-2.5 V and it has a very low power consumption. It is ideal for use where solar panels are used as power source. The 525 T is a combined DO and temperature probe with two output signals. The Model...

  • OxyGuard - Model 420 - Membrane Covered Galvanic Oxygen Probe

    OxyGuard - Model 420 - Membrane Covered Galvanic 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...

  • OxyGuard - Temperature Probe

    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...

  • OxyGuard - Model DO - Profile Probe

    OxyGuard - Model DO - Profile Probe

    The OxyGuard Profile is a small dissolved oxygen probe with a very fast response time and a short temperature equilibrium time. It is designed specially for profiling measurements in ponds, lakes and the sea. It is (unlike other types of dissolved oxygen probe) NOT sensitive to hydrogen sulphide!

  • OxyGuard - Mini Probe

    OxyGuard - Mini Probe

    The OxyGuard Mini Probe is a membrane covered galvanic cell that generates an electrical signal proportional to the oxygen pressure it senses, whether it is placed in water, air, oil, wine etc.. Just 15mm in diameter and 101 mm in length it can, for example, be lowered into a wine bottle. The probe acts as a battery with output voltage that is proportional to the oxygen concentration. it does not need an applied voltage og...

  • OxyGuard - Model EX - Probe for Classified Areas

    OxyGuard - Model EX - Probe for Classified Areas

    The OxyGuard probe is a membrane covered galvanic cell that generates an electrical signal proportional to the oxygen pressure it senses, no matter which medium it is placed in. The probe can measure very small oxygen concentrations in inert or explosive gases as well as the oxygen content of ambient air and the purity of oxygen gas.

  • Hand-Held and Portable Aquaculture Monitoring

  • Polaris - Hand-Held Meter

    Polaris - Hand-Held Meter

    The Handy Polaris hand-held meter makes it easy to measure dissolved oxygen and temperature. The flat foil pushbuttons are easy to operate and the instrument is always ready to use – just press the “on” button and measure.

  • Polaris  - Model TGP - Hand-Held Gas Pressure Meter

    Polaris - Model TGP - Hand-Held Gas Pressure Meter

    The OxyGuard Handy Polaris TGP (Total Gas Pressure) is a hand-held gas pressure meter. It can operate in three modes, one where it acts as a standard Handy Polaris dissolved oxygen (DO) meter, one where it is a total gas pressure meter that shows pressures as percent saturation values and one where it is a total gas pressure meter that shows pressures as volume percentages. The user can choose which value is shown in large figures...

  • Handy Salinity Hand Held Instrument

    Handy Salinity Hand Held Instrument

    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.
