From advanced aquifer characterization to economical data collection, the In-Situ
Level TROLL series of level/pressure instruments yields accurate level measurement
and offers powerful data logging and flexible communications. The Level TROLL 700
is the professional's choice for accurate water level monitoring and aquifer characterization.
Its logging options expand functionality with linear average, step linear, true logarithmic,
and fast linear (4x/second) logging in addition to standard linear, fast linear,
and event. The Level TROLL 700 has a fast logging rate of 4 logs per second and "Pause"
and "Restart" logging features (restart logarithmic sampling within the same file).
The Level TROLL 700 can be used effectively for aquifer characterization (pumping
and slug tests), multi-well testing, multi-zone aquifer monitoring, real-time monitoring
via telemetry, stormwater monitoring, and tide/harbor monitoring.
