• 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)

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 XSG/AG connectors. Like XSG/AG connectors, wet-pluggables need proper lubrication & require care during use to avoid trapping water in sockets.

See document 67096. '.I' designation indicates that brackets are to be installed on instrument at factory.

Cable fits loosely through wire guide, & is clamped only at mounting clamp. See document 67094. (photo is of 37-SIP; 37-SI is similar). '.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
• 5/8 in./16 mm diameter: 5/8-18 UNF
• 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:

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).

• Cleaning instructions require use of syringe & tubing assembly at intake end of conductivity cell (requiring 1 barbed cap).
• Storage instructions require looping Tygon tubing from end to end of conductivity cell (requiring 2 barbed caps).

Storm shipping case with custom foam inserts holds up to 4 MicroCATs that do not include dissolved oxygen — IMP, IM, SMP, SM, SIP, SI.

• Injection molded case with HPX resin plastic body, recessed wheels, automatic pressure equalization valve, hinged push-button latches, fold-down padded handle, & O-ring seal. Meets airline luggage regulations.
