In-Situ TROLL External Lithium Battery Pack supplements the TROLL internal battery during long-term deployments. When this power source is connected, the Aqua TROLL instrument will use the external battery source first and switch to the internal battery when external battery power is depleted. Internal battery life is dependent on sampling rate. External batteries can be expected to last about a year, regardless of sampling rate.
Flexible applications, useful for frequent fast sampling or long-term deployments
Extends deployment durations for a greater range of sampling
Fully submersible, tested to 2000 PSI for 14 days
