Conductivity cells are made of glass, which is breakable. If a cell is cracked, it typically causes a salinity shift or erratic data. However, if the crack occurs at the end of the cell, the sensor will continue to function normally until water penetrates the epoxy...
The free-falling profiler is designed to profile away from a small boat or large ship to avoid any potential shadow effects. The instrument is deployed by hand from the leeward side of the vessel and allowed to descend while the vessel drifts downwind. When the...
The BOSS was specifically designed for bolt-on integration with an Argo profiling float. As such, the design and telemetry interfaces are not set up for stand alone or real-time profiling.
Plug the ends of the conductivity cell to prevent the cleaning solution from getting into the cell. Then soak the entire instrument in white vinegar for a few minutes. After scraping off the barnacles and marine growth, rinse the instrument well with fresh...
Adhesive Teflon tape (actually, UHMW tape — Ultra High Molecular Weight polyethylene) provides insulation to prevent damage due to contact of dissimilar metals. It is typically used by Sea-Bird on the inside of hose clamps used for mounting instruments, where U-bolts...
For convenience while examining differences in density between two water parcels, Sigma-density values are typically used by oceanographers. Sigma-density values allow the oceanographer to focus on the last 6 to 7 digits in the density value (when assuming 5 decimal...
Digiquartz pressure sensors are used in the SBE 9plus, 53, and 54. The SBE 16plus V2, 16plus-IM V2, 19plus V2, and 26plus can be equipped with either a Druck pressure sensor or a Digiquartz pressure sensor. All other instruments that include pressure use a Druck...
Sea-Bird typically recommends using the Dam/Blok and EverGrip products from PMI Industries. DamBlok makes the electrical splice and EverGrip provides the strain relief on the cable. See an example of how these products can be used.For a quick electrical...

It is not necessary to put the instrument in water to test it. It will not hurt the conductivity cell to be in air.If there is a pump on the instrument, it should not be run for extended periods in air.Profiling instruments (SBE 9plus, 19, 19plus, 19plus V2, 25,...
We are excited to exhibit at the upcoming MTS Buoy Workshop this year from May 20 - 23. Please come visit us in our backyard at table #1 to chat with our team to learn more about the latest at Sea-Bird Scientific and oceanography. We'll have associates from...
