SBE 39 Temperature (Pressure optional) Recorder
Configuration Details

SBE 39 Housing Selections (option numbers out of order for consistency with previous price list) -- MUST SELECT ONE

• 39-1g & -1c have internal connector; instrument setup & data upload require opening housing by unscrewing end cap. 801413 cable is included with these options.
• 39-1h & -1d have standard (Impulse XSG) external connector, allowing instrument setup & data upload without opening housing. Cable is not included with these options; order cable separately (see SBE 39 Accessories below).
• 39-1i & -1f have wet-pluggable (MCBH) external connector, allowing instrument setup & data upload without opening housing. Cable is not included with these options; order cable separately (see SBE 39 Accessories below).
  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.

Pressure sensor is installed in end cap, & is not field replaceable / swappable. While highest pressure rating gives you most flexibility in using 39, it is at expense of accuracy & resolution. It is advantageous to use lowest range pressure sensor compatible with your intended maximum operating depth, because accuracy & resolution are proportional to pressure sensor's full scale range. For example, comparing 2000 & 7000 m sensors --

• 2000 m sensor:
  initial accuracy = 2 m (= 0.1% * 2000 m),
  resolution = 0.04 m (= 0.002% * 2000 m)
• 7000 m sensor:
  initial accuracy = 7 m (= 0.1% * 7000 m),
  resolution = 0.14 m (= 0.002% * 7000 m)

SBE 39 shown with option 39-1c (10,500 m titanium housing, internal I/O connector) & 39-2b (External thermistor, in pressure protected sheath), as well as 1 mounting clamp.

Net fender retains half the mooring clamps. All hardware is captured within, guaranteeing no loss of nuts or bolts during deployment. Attach SBE 39 to mooring cable in 2 steps:

1. Place net fender & attached clamps against mooring line. Push SBE 39 into clamp guides.
2. Holding SBE 39 & net fender with 1 hand, tighten clamp bolts with a driver in free hand.
