Power Options
Internal Power - Batteries
Internal batteries are not user-replaceable. The
approximate percentage of the power remaining in an
internal battery is displayed on the Home Screen when
an instrument is connected to Win-Situ
®
Software.
External Power - External Battery Packs
External battery packs can significantly increase the life
of an instrument, either for long-term deployments or to
preserve an aging instrument.
TROLL Battery Pack (PN 0051450)
The sealed, submersible TROLL Battery Pack (lithium)
supplements internal battery power when an instrument
is used for fast, frequent sampling or during long-term
deployments. When this power source is connected, the
instrument will use the external battery source first and
switch to the internal batteries when external battery
power is depleted. Total battery life depends on the
sampling speed.

TROLL Replaceable Battery Pack (PN
0090000)
The TROLL Replaceable Battery Pack supplements
internal battery power when a Level TROLL or Aqua
TROLL 100 or 200 Instrument is used for frequent, fast
sampling or during long-term deployments. When this
power source is connected, the TROLL instrument will
use the external battery source first and switch to the
internal batteries when external battery power is
depleted. Battery life depends on sampling rate. This
battery pack allows for 1.5 V UM-3 or size AA batteries
(8) that are replaced by the user.

Antifouling Products
TROLL Shield Nose Cone (PN 0081480)
The copper TROLL Shield Nose Cone is designed to
reduce macro- and micro-fouling of the pressure sensor
on Level TROLL and Aqua TROLL Instruments.
Reduced fouling on the sensor improves measurement
accuracy and extends the length of deployments.
For optimum performance, the TROLL Shield Nose
Cone should be replaced every 12 months or sooner if
site conditions are extremely harsh.
