In-Situ Level TROLL 400 / 500 / 700
The Level TROLL series comprises 3 powerful level loggers for pressure and temperature measurement. With extended measuring modes, particularly slim design (< 1 inch) and titanium probe body and pressure sensor, they are specially designed for measurements in groundwater - even under extreme conditions and up to 700 m water column. However, log frequencies up to 4 Hz and the high precision also make them ideal for demanding measurement series in surface water or industrial plants.
In addition to the Twist-Lock cable connection, all Level Trolls have a BT interface and are telemetry-capable with the new In-Situ VuLink.
