OxyGuard Ocean D.O. Probe Small-Size D.O. Probe for Stationary Measurements in Ponds, Lakes and Oceans Stand-Alone Probe. Probe for incorporation into multiple parameter deep-sea probe system O-ring here for measurement O-ring here for transport 23 mm dia. General Information This small-size version of the standard OxyGuard dissolved oxygen probe is a membrane-covered galvanic cell that generates its own voltage. The Ocean D.O. 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. Due to an ingenious pressure compensation system the probe is insensitive to pressure changes, and, as with all OxyGuard dissolved oxygen probes, it has built-in temperature compensation. It is, unlike some other types of dissolved oxygen probe, NOT sensitive to hydrogen sulphide. The Ocean D.O. Probe delivers a millivolt output directly proportional to the oxygen pressure that it senses. The connected electronics can therefore be quite straightforward. The Ocean can be delivered in a mounting configuration to suit the user. The standard version has an M18 x 1 mm thread mount and 50 cm leads for moulding into a multi-parameter sonde as an OEM device. The stand-alone version is also available, this has 3m cable unless otherwise ordered. Please note that for profiling measurements and measurements using moving probes the DO Profile probe should be used.

Technical Information Technical Advantages * Extremely high stability. * No regular maintenance needs - just wipe the membrane from time to time. * Unlimited theoretical lifetime - if needed the membrane can easily be replaced by anyone - at negligible cost. * Correct measurements with low water movement. * Galvanic type - True zero. * Built-in temperature compensation. * No practical limit to cable length. * NOT sensitive to hydrogen sulphide. * Can be delivered as stand-alone probe or made specially to fit into your exploratory device. * Anti-fouling probe protector available.
