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.
The instrument is powered by 3.6 VDC, supplied by a sealed, non-replaceable AA
lithium battery. Battery life depends on sampling speed. The battery typically lasts for
10 years or 2,000,000 readings, whichever occurs first.
When an instrument is wired to a data logger or PLC controller, power to the instrument
is supplied by the data logger or controller.
AC Adapter
The AC adapter provides 24 VDC, 0.75 A, AC input 100-250 V and includes a North
American power cord. The TROLL Com Communication Device includes an external
power input port for connection to the AC adapter.
Description Part Number
AC Adapter 24 VDC 0052440
Use only In-Situ Inc.'s AC adapter. Damage to the instrument
caused by the use of third-party converters is not covered by the
warranty.
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
The sealed, submersible TROLL Battery Pack 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.
