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

The measurement process in standard dissolved oxygen probes is such that the whole probe
must attain temperature equilibrium with the surroundings before correct measurements are
obtained. The OxyGuard Profile overcomes this problem – it correctly measures first time
thanks to its innovative and technologically advanced design!

As with all OxyGuard dissolved oxygen probes, the Profile has built-in temperature
compensation. It delivers a millivolt output directly proportional to the oxygen pressure that it
senses. The electronics needed to process the probe output can therefore be very simple!

  • Very fast response time to changes in temperature.
  • Very fast response time to changes in oxygen concentration.
  • Built-in temperature compensation.
  • Low output impedance - easy signal conditioning.
  • Extremely easy and inexpensive to maintain.
  • Output signal = Typically between 10 and 40 mV in air.
  • Operating temperature = 0 to 40 C.
  • Operating pressure = Max 15 bar (150m depth in water).
  • Temperature compensation = Built into the probe.
  • Accuracy (oxygen) = =/- 1% of measured value.
