Part # Description Notes
43 DISSOLVED OXYGEN SENSOR - Sea-Bird polarographic membrane sensor for pumped CTD applications, 0-5 volt temperature-compensated oxygen signal. Includes plenum & complete documentation. Specify: housing/connector and Profiling or Mooring configuration selections.

Shown with optional 7000 m titanium housing
SBE 43 can be ordered in several ways:
  • By itself; consult Sea-Bird to order interface cable or mount kit separately, if needed.
  • As an option in SBE 9plus, 16plus V2, 16plus-IM V2, 19plus V2, or 25plus listing, complete with sensor, CTD interface cable, & mount kit.
For sensor with frequency output, compatible with SBE 52-MP Moored Profiler CTD or Glider Payload CTD, see SBE 43F. Another version of 43F is an integral part of SBE 37 MicroCAT (SMP-IDO, SIP-IDO, IMP-IDO).
SBE 43 Housing and Connector Selections -- MUST SELECT ONE
43-1a 7000 m titanium housing, Standard (XSG) connector

Titanium housing

Plastic housing

SBE 43 is available in titanium (7000 m) or plastic (600 m) housing. A 10,500 m titanium housing is available on request; contact Sea-Bird for details.
Note: In 2007, Sea-Bird began transitioning from using white plastic parts to black plastic parts for SBE 43. Currently, all plastic on both plastic housing & titanium housing versions of SBE 43 are manufactured with black plastic.

Wet-pluggable connectors may be mated in wet conditions. Their pins do not need to be dried before mating. By design, water on connector pins is forced out as connector is mated. However, they must not be mated or un-mated while submerged. Wet-pluggable connectors have a non-conducting guide pin to assist pin alignment & require less force to mate, making them easier to mate reliably under dark or cold conditions, compared to our standard (Impulse XSG/RMG) connectors. Like standard connectors, wet-pluggables need proper lubrication & require care during use to avoid trapping water in sockets.

SBE 43 Profiling or Mooring Selection -- MUST SELECT ONE
43-2a Profiling configuration (fast response membrane, includes dynamic response characterization) 43-2a profiling configuration uses a 0.5-mil thick membrane.

43-2b mooring configuration uses a 1-mil thick membrane, which has a slower response but is more rugged.

See Application Note 64 for information on response times for each membrane.

43-2b Mooring configuration (rugged membrane for enhanced long term stability, dynamic response characterization omitted)
SBE 43 Spares & Accessories
171491 SBE 43 interface cable (9plus), Standard connectors, 0.7 m (DN 32496) These interface cables are compatible with SBE 9plus, 19plus, 19plus V2, 25, or 25plus if connecting just SBE 43 to bulkhead connector. If connecting 2 sensors to 1 bulkhead connector, a Y-cable is required in place of one of these straight cables.

Note: 172447 and 172448 are also used for integrating SBE 43 with SBE 16plus, 16plus-IM, 16plus V2, or 16plus-IM V2. However, for moored applications, Sea-Bird usually recommends SBE 63 Optical Dissolved Oxygen Sensor instead of SBE 43.

172447 SBE 43 interface cable, Standard connectors (19plus/19plus V2/25/25plus), 1.1 m (DN 32496)
172218 SBE 43 interface cable (9plus), Wet-pluggable connectors, 0.7 m (DN 32654)
172448 SBE 43 interface cable, Wet-pluggable connectors (19plus/19plus V2/25/25plus), 1.1 m (DN 32654)
801617 SBE 43 Plenum Assembly, Version 2, Black Acetal In 2007, Sea-Bird began transitioning from using white plastic parts to black plastic parts for SBE 43, to minimize exposure to light, improving resistance to bio-fouling. Currently, all plastic on both plastic housing & titanium housing versions of SBE 43 are manufactured with black plastic. If desired, customers may retrofit existing SBE 43s.
50126 SBE 43 mount kit for SeaCATs Use 50126 for mounting SBE 43 to SBE 16, 16plus, 16plus-IM, 16plus V2, 16plus-IM V2, 19, 19plus, or 19plus V2 SeaCAT.

90087 Universal plumbing kit (includes pump air release valve, Y-fitting, and tubing) -- Application note 64-1 Application Note 64-1 details installation of plumbing for SBE 43 & pump on a CTD.
30388 Tygon tubing, 1/2" ID x 3/4" OD, 2 m -- main plumbing

30388 tubing shown with SBE 9plus
30388 is main plumbing, attaches to pump, conductivity sensor, 1/2" nylon hose barb Y-fitting, etc.
31450 Tygon tubing, 1/2" ID X 3/4" OD, 2 m, Black -- main plumbing, minimizes light exposure 31450 can be used in place of 30388 plumbing tubing to minimize exposure to light, improving resistance to bio-fouling for moored applications. Beginning in 2007, Sea-Bird is using this black tubing on all new moored instruments (SBE 16plus/16plus V2 and 16plus-IM/16plus-IM V2 CTDs) that are integrated with an SBE 43. If desired, customers may field retrofit plumbing on existing systems.
