In-Situ Level TROLL
Level & Temp Dataloggers
The Level TROLL® contains
everything needed for monitoring
level/pressure and temperature all
in one design. There are three data
logging instruments to choose from
(Level TROLL 700, 500 or 300) and
all are manufactured for accuracy,
ruggedness and easy usability. You
can have total condence whatever
your application when using Level
TROLL® products.
Level TROLL 300
Simple, reliable and economical. Ideally suited for non-
vented long-term level and/or pressure monitoring.
Level TROLL 500
Highly accurate, reliable, and aordable. Ideally suited
for long-term level and/or pressure monitoring. Fresh
or marine.
Level TROLL 700
Our top-of-the-line unit. Powerful and exible
level monitoring. Optimized for multi-step aquifer
testing, precision level monitoring, and research.
BaroTROLL
Barometric Pressure logger
The BaroTROLL® is used to measure
and log barometric pressure and
temperature changes. It can be used
by itself or together with a non-
vented (absolute) Level TROLL® to
compensate the level readings for
uctuations in barometric pressure
where vented cable cannot be used.
Superior Accuracy and
Performance
In-Situ® uses the newest sensor
technologies. All instruments
undergo an extensive full-scale
calibration procedure for both
pressure and temperature.
Rugged and Reliable
All Level TROLL sensors are designed
for use in many applications. Deploy
316 stainless steel (300) and titanium
(500, 700) sensors into most types of
environmental waters.
Flexible Communications
The Level TROLL 300, 500 and 700
instruments feature Modbus (RS485),
SDI-12 and 4-20mA outputs. Connect
each of these units to a SCADA or PLC
system.
