Specify: mooring clamp wire size selection to match O.D. of wire jacket. Compare features of the numerous SBE 37 MicroCAT models (SM, SMP, SMP-IDO, SMP-ODO, SI, SIP, SIP-IDO, SIP-ODO, IM, IMP, IMP-IDO, & IMP-ODO).

37-IMP-ODO MicroCAT includes:

  • Inductive modem interface
  • Memory
  • internal, integral Pump
  • integrated Optical Dissolved Oxygen sensor

Photos of standard shipment.

Communicating with 1 or more 37-IMP-ODOs requires use of Sea-Bird Inductive Modem Module (IMM) or Surface Inductive Modem (SIM), which provide serial interface between user’s computer & up to 100 IM instruments coupled to single cable. Purchase IMM/SIM & optional Inductive Cable Coupler (ICC) separately.

Also see:

  • SBE 39-IM for temperature and optional pressure recorder with inductive modem interface.
  • SBE 16plus-IM V2 SeaCAT for CTD with inductive modem interface and auxiliary sensor input capability.
  • SBE 44 Underwater Inductive Modem or Underwater Inductive Modem Module (UIMM) to integrate an RS-232 sensor with Sea-Bird's inductive modem telemetry system.

SBE 37-IMP-ODO ShallowCAT Option -- Plastic (PET-P) Housing with 350 meter depth rating
37IMP-2 350 m plastic housing instead of standard titanium housing (CREDIT)


37-SMP-IDO shown;
plastic housing detail for 37-IMP-ODO similar
Substituting plastic housing for standard 7000 m titanium housing provides lower cost option for shallow deployments.
SBE 37-IMP-ODO Pressure Sensor Range (Depth) Options
37IMP-3a 20 m strain gauge pressure sensor Pressure sensor is installed in end cap, & is not field replaceable / swappable. While highest pressure rating gives you most flexibility in using 37-IMP-ODO, 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)
37IMP-3b 100 m strain gauge pressure sensor
37IMP-3c 350 m strain gauge pressure sensor
37IMP-3h 600 m strain gauge pressure sensor
37IMP-3d 1000 m strain gauge pressure sensor
37IMP-3e 2000 m strain gauge pressure sensor
37IMP-3f 3500 m strain gauge pressure sensor
37IMP-3g 7000 m strain gauge pressure sensor

SBE 37-IMP-ODO Spares & Accessories
801542 AF24173 Anti-Foulant Device pair (spare, bagged, labeled for shipping) Anti-foulant devices fit into anti-foulant device cups at conductivity cell intake and plumbing exhaust, under the conductivity cell guard. Anti-foulant devices included with standard shipment; these are spares.
Useful life varies, depending on several factors. We recommend that customers consider more frequent replacement when high biological activity & strong current flow (greater dilution of anti-foulant concentration) are present. Moored instruments in high growth & strong dilution environments have been known to obtain a few months of quality data, while drifters that operate in non-photic, less turbid deep ocean environments may achieve years of quality data. Experience may be strongest determining factor in specific deployment environments.
50441 SBE 37 & 44 lithium batteries (spare), package of twelve 3.6V AA cells (Saft LS 14500) One set of batteries is included with standard shipment; 50441 are spares. Batteries are easily accessed by removing 2 screws from modem end cap & pulling out end cap. Shipping restrictions apply for lithium batteries; see SBE 37-IMP-ODO manual for details.

801863 is battery holder, without batteries. Battery holder is included with standard shipment; this is a spare.
NOTE: Other MicroCATs use a battery pack with a red cover plate; the wiring of that pack is different from this one, and cannot be used with ODO MicroCATs (37-IMP-ODO or 37-SMP-ODO).
