In-Situ LevelTROLL 700

Introducing the Level TROLL® 700... the next breakthrough for professional water level monitoring applications including single or multi-step aquifer testing, precision river gauging, tidal influence studies, wave characterization, geothermal research, storm-event monitoring and more!

The Level TROLL® 700 features a rugged, all-titanium construction that is TIG welded to eliminate o-ring seals, Twist-Lock connectors, an ultra-low power system that eliminates the need to change batteries, and it is only 18.3mm (0.72 in) in diameter making it perfect for 1-inch wells or observation tubing. The 700 series of the Level TROLL® offers new logging modes such as Linear, Linear Average, Event, True Logarithmic, Step Linear, and Fast Linear for complete customization. Additional benefits of the Level TROLL® 700 include “Pause” and “Re-Start” logging features, a larger memory (350,000+ data points), 0.25 sec sampling (4 samples per second), ability to store and manage up to 50 log files, user notes, advanced compensation settings, and more.

The Level TROLL® comes standard with RS-485 Modbus, SDI-12, and 4-20mA communication options. It can be operated using a PC or a RuggedReader® handheld and it can easily be connected to a SCADA or other online systems.

Applications:

• Multi-step aquifer testing
• Slug tests
• Pumping tests
• Tidal influence & wave characterization
• River, lake, stream gaging
• Landslide & flood prevention
• Stormwater monitoring
• Flow measurements
• Research, studies
• Marine buoys
• Water pumping management
• Estuaries and coastal monitoring

Features & Benefits:

• Ultra-rugged, all-titanium design – Perfect for fresh and marine water monitoring. No more worries about corrosion. Excellent for marine, brackish and acidic sites.
• Super accurate sensors – record minute changes in water level and temperature.
• TIG-welded seals – Prevents flooding of instrument.
• Ultra-low power system guarantees 5 years or 2-million readings – Forget changing batteries or running out of power.
• Uses external battery or line power – no worries about running out of power.
• RS-485 MODBUS, SDI-12, and 4-20mA – provides for easy connections to existing and online systems
• Twist-Lock connectors that “lock” tight – 100% reliability
• Halogen-free cables (LSZH rated) – no worries of toxic fumes if submitted to fire
• Sealed desiccant options – allow for barometric compensation for maximum accuracy while preventing water & humidity intrusion
• Extend cables by simply adding additional segments – maximizes your investment and maintain flexibility with your unit.
• -20 to 80ºC temperature range – useful for geothermal and hot spring research and monitoring
• Easiest ever Win-Situ^® software – get the data you need fast! Large, sizable display that’s easy to see from a distance.
• Linear logging – perfect for long-term monitoring
• Pause logging feature – Pause logging when removing a unit. Reinstall and restart where you left off!
• Specify start and stop times for logging – collect the data you need up to the date you want and no more
• Ability to “undelete” files from the unit – no worries of accidentally deleting your data.
• Data saved by sites not files – collect and save information by site automatically. No need to transfer data later.
• Easy-to-read memory and battery gauges – know exactly how much is left
• Friendly Wizards guide every step – reduces complicated steps and the need for tedious manuals
• Submersible ranges up to 351m / cable length up to 1200m – measure to the depth you need.
• FCC and CE emission tested – prevents susceptibility to outside emission interference and transient electrical surges
• Version, range, and manufacturing info printed on side of the unit – know the details of the unit without opening the software. Reduces accidental over pressuring

Level TROLL^® 700 only features & benefits

• Restart logarithmic sampling within the same file – Perform multi-step aquifer tests with ease!
• New logging modes – Linear, Linear Average, Event, True Logarithmic, Step Log, Fast Linear. Log the way you want to!
• Up to 50 logging files can be programmed in the Level TROLL^® – complete flexibility and new possibilities in logging
• Takes samples as fast as 0.25 seconds (4 samples/sec) – perfect for earthquake detection and wave modeling
• Up to 350,000 data points of memory (4MB) – reduces the interval between data collection
