Internal
Batteries
(nominal
capacity)
Standard 9 alkaline D-cells (Duracell MN1300, LR20) - 14 amp-hours.
Optional NiMH battery pack – 8 amp-hours.
Optional Ni-Cad battery pack - 4.4 amp-hours.
External Power
Supply
9-28 VDC; current requirement varies, depending on voltage and pump:
• 3 Amps at 9V input - SBE 5M pump (cannot use SBE 5T or 5P pump
with 9V input)
• 0.5 Amps at 12V input – SBE 5M pump
• 3 Amps at 12V input – SBE 5T or 5P pump
• 0.5 Amps at 19V input – SBE 5M pump
• 1.5 Amps at 19V input – SBE 5T or 5P pump
Power
Requirements
Sampling: 70 mA
Pump: Standard SBE 5M 100 mA
Optional SBE 5P or 5T 150 mA
Communications: 65 mA
Quiescent: 20 μA
Moored Mode sampling time:
• Minimum 2.5 seconds/sample [strain-gauge pressure, pump running
while sampling (MooredPumpMode=2), 1 measurement/sample,
no delays].
• Minimum 2.45 seconds/sample [Quartz pressure, pump running
while sampling (MooredPumpMode=2), 1 measurement/sample,
no delays].
• Add 0.25 seconds for each additional measurement/sample
(NCycles >
2).
• Add pump on-time (0.5 second) if pump running before taking sample
(MooredPumpMode=1).
• Add time for user-programmed delay before sampling
(DelayBeforeSampling=).
Approximate Battery Endurance

With Duracell MN 1300 (LR20) cells. Dependent on sampling scheme; see
Battery Endurance for example calculations.
Auxiliary
Voltage and RS-
232 Sensors
Auxiliary power out: up to 500 mA at 10.5 - 11 VDC
Voltage sensor A/D resolution: 14 bits
Voltage sensor input range: 0 - 5 VDC
Housing Depth /
Materials
Standard: 600 meter (1950 ft) - acetal copolymer (plastic).
Optional: 7000 meter (22,900 ft) - 3AL-2.5V titanium
Weight
With plastic housing, no pump:
in air 7.3 kg (16 lbs) in water 2.3 kg (5 lbs)
With titanium housing, no pump:
in air 13.7 kg (30 lbs) in water 8.6 kg (19 lbs)
Pump adds (in air) 0.3 to 0.7 kg (0.6 to 1.5 lbs), depending on pump
model selected. See pump brochures for details.
Optional Cage
PN 801269 cage for 19plus V2 with strain-gauge pressure:
1016 x 241 x 279 mm (40 x 9.5 x 11 in.), 6.3 kg (14 lbs)
PN 801270 cage for 19plus V2 with Quartz pressure:
1219 x 241 x 279 mm (48 x 9.5 x 11 in.)
PN 23892 cage for 19plus V2 mounted horizontally in cage in extension
stand (beneath SBE 32 Carousel Water Sampler):
965 x 279 x 305 mm (38 x 11 x 12 in.)
Note:
Battery packs for
NiMH, Ni-Cad, and
alkaline batteries differ
– you cannot put
alkalines in the NiMH
or Ni-Cad battery pack
or vice versa.
