OxyGuard D.O. Profile Dissolved Oxygen probe for Profiling Measurements in the Environment O-rings Membrane cap Membrane General Information 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! 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 measures correctly immediately 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! The OxyGuard Profile is delivered with a M18 x 1 mm thread mount and 50 cm leads as illustrated, but can be delivered in other configurations on request.

Technical Advantages * Very fast response time to changes in temperature. * Very fast response time to changes in oxygen concentration. * Not cross-sensitive to hydrogen sulphide. * Galvanic type - the OxyGuard probe makes its own electricity. -Uses a chemical principle superior to that of traditional DO probes. -negligible zero error - no zero adjustment needed. -No warm-up time - always ready to measure. -No external excitation voltage to calibrate. * Built-in temperature compensation. * Low output impedance - easy signal conditioning. * Extremely easy - and inexpensive - to...
