SEAPHOX V2

 

  
SeaPHOx Configuration Selections — MUST SELECT ONE
SEAPHOX.0 SeapHOx™ V2 Ocean CT (no pressure sensor) + pH + DO sensor. Integrates the SeaFET (v 2.0) Ocean pH sensor with flow cell and the Sea-Bird SBE 37SMP-ODO MicroCAT C and T Recorder with Integrated SBE 63 Optical Dissolved Oxygen sensor (ODO) with titanium housing. 50 meter depth rating. All sensors using wet-pluggable (MCBH) connector. Includes SeapHOx integration kit (mount brackets, flow tube adapter, Y-cable, RS-232 programming cable, hardware).

Pressure sensor is installed in MicroCAT end cap (behind mount clamp), & is not field replaceable / swappable. While highest pressure rating gives you most flexibility in using MicroCAT, 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 20 & 100 m sensors:

  • 20 m sensor:
    initial accuracy = 0.02 m (= 0.1% * 20 m),
    resolution = 0.0004 m (= 0.002% * 20 m)
  • 100 m sensor:
    initial accuracy = 0.1 m (= 0.1% * 100 m),
    resolution = 0.002 m (= 0.002% * 100 m)
SEAPHOX.1 SeapHOx™ V2 Ocean CTD + pH + DO sensor. Integrates the SeaFET (v 2.0) Ocean pH sensor with flow cell and the Sea-Bird SBE 37SMP-ODO MicroCAT CTD with 20 meter pressure sensor, with Integrated SBE 63 Optical Dissolved Oxygen sensor (ODO) with titanium housing. 20 meter depth rating. All sensors using wet-pluggable (MCBH) connector. Includes SeapHOx integration kit (mount brackets, flow tube adapter, Y-cable, RS-232 programming cable, hardware).
SEAPHOX.2 SeapHOx™ V2 Ocean CTD + pH + DO sensor. Integrates the SeaFET (v 2.0) Ocean pH sensor with flow cell and the Sea-Bird SBE 37SMP-ODO MicroCAT CTD with 100 meter pressure sensor, with Integrated SBE 63 Optical Dissolved Oxygen sensor (ODO) with titanium housing. 50 meter depth rating. All sensors using wet-pluggable (MCBH) connector.  Includes SeapHOx integration kit (mount brackets, flow tube adapter, Y-cable, RS-232 programming cable, hardware).
SBE 37-SMP Mooring Clamp Wire Size Selections (Specify clamp to match O.D. of mooring wire jacket; cannot accommodate wire size greater than 1.2 in. diameter) — MUST SELECT ONE
50465.I Wire guide & mounting clamp for 1/4 in. diameter mooring wire

Cable fits loosely through wire guide, & is clamped only at mounting clamp. See document 67219. '.I' designation indicates that guide and clamp are to be installed on instrument at factory.

Thread for clamping to mooring cable:

  • 1/4 in. diameter: 1/4-28 UNF
  • 5/16 in./8 mm diameter: 5/16-24 UNF
  • 3/8 in. diameter: 3/8-24 UNF
  • 1/2 in. diameter: 9/16-12 UNC
  • 6 mm diameter: 1/4-20 UNF
  • 10 mm diameter: 7/16 -14 UNF
  • 12 mm diameter: 1/2-13 UNF

Clamp Size Note: Mooring wire is typically specified by wire size, not by outer diameter (O.D.) of the mooring wire jacket. Verify the wire jacket O.D. before selecting the clamp size. The clamp size must be less than or equal to the wire jacket O.D. but larger than the wire diameter. For example, Mooring System Inc.’s specifications for 3x19 wire rope (in 2016) are as follows:

Wire Diameter Jacket Diameter Recommended Sea-Bird Clamp
3/16 inch (5.0 mm) 0.255 inch (6.5 mm) 1/4 inch
1/4 inch (6.5 mm) 0.330 inch (8.4 mm) 5/16 inch
5/16 inch (8.0 mm) 0.392 inch (9.9 mm) 3/8 inch
3/8 inch (9.5 mm) 0.453 inch (11.5 mm) 10 mm (0.394 inch)
7/16 inch (11.1 mm) 0.5 inch (12.7 mm) 1/2 inch

For mounting on a rope, verify the rope outer diameter, and select a clamp smaller than the rope O.D. to account for the rope compressibility (for example, for 5/16 inch rope, select a ¼ inch clamp; a 5/16 inch clamp will be too large).
50469.I Wire guide & mounting clamp for 5/16 in. or 8 mm diameter mooring wire
50470.I Wire guide & mounting clamp for 3/8 in. diameter mooring wire
50473.I Wire guide & mounting clamp for 1/2 in. diameter mooring wire
50467.I Wire guide & mounting clamp for 6 mm diameter mooring wire
50471.I Wire guide & mounting clamp for 10 mm diameter mooring wire
50474.I Wire guide & mounting clamp for 12 mm diameter mooring wire
50479.I Alternative mounting - plastic brackets to provide through-bolt mounting to a flat surface See document 67218. '.I' designation indicates that brackets are to be installed on instrument at factory.
