Level TROLL 700
|
The Level TROLL® 700 instrument is enclosed in a solid titanium housing with a titanium sensor and expanded functionality. This provides exceptional versatility for long- and short-term groundwater and surface-water monitoring and hydraulic testing even when used in saltwater or leachate. Both vented (gauged) and non-vented (absolute) instruments are available to record changes in water level, pressure and temperature.
Choose the Level TROLL 700 for freshwater, saltwater and industrial process applications where extended programming functionality is required. Ideal for aquifer characterisation, pumping tests and slug tests.

See our Vented System Sheet or Non-Vented System Sheet for full details of components and options.
Why Choose In-Situ Loggers?
Unlike the competition, In-Situ Loggers are accurate across their full pressure and temperature range. Calibration is traceable to national standards (NIST) - others use in-house standards only. We use a common easy to use software platform across our entire range of loggers. We manufacture and deliver to meet customer expectations backed up with dedicated and professional customer service and technical support.

Level TROLL 700 Vented (Gauged)
|
Choose from 6 pressure ratings, from 3.5m to a maximum of 350m equivalent water depth. For normal real time communication use: - suspend from vented Rugged Cable - choose other cable accessories as needed(e.g. dessicants) - programme and download data using a Troll Com communications device. Vented loggers automatically compensate for barometric pressure and do not need a seperate baro unit. The Level TROLL 500 vented can be used with high quality Direct-Read Non-Vented RuggedCable for real-time data access. Choose from 3 pressure ratings, equivalent to a maximum of 11m, 60m or 200m water depth. A TROLL com communications device (USB or RS232) is used to connect to the end of the direct-read cable where used. For barometric compensation a Rugged BaroTROLL is required. For standalone use, suspend from inexpensive stainless steel wire or kevlar cord. A separate Troll Com communications device is needed to program and download data. |

Level TROLL 700 Non-Vented (Absolute)
|
Choose from 5 pressure ratings, from 11m to 700m equivalent water depth. For standalone use: - select a titanium twist-lock hanger for the top of the logger - suspend from inexpensive stainless steel wire or kevlar cord. - programme and download data using a Troll Com communications device. For real time communications: - suspend from non-vented Rugged Cable - programme and download data using a Troll Com communications device. For barometric compensation with standalone and direct read options: - select a BaroTROLL with backshell hanger. |

TROLL Shield Nose Cone
|
For high fouling environments choose a Troll Shield copper nose cone. This has a simple screw-thread for attachment to the Level TROLL and replaces the standard titanium nosecone. The Troll Shield nosecone provides signicant additional protection against corrosion and will ensure your logger survives longer and maintains greatest accuracy in saltwaters of all types. |

Baro TROLL
|
The titanium Baro TROLL instrument measures and logs barometric pressure and temperature It can be deployed using direct read RuggedCable or standalone. For standalone use, select a titanium twist-lock backshell hanger (cap). Win-Situ Baro Merge™ software simplifies compensation of water level data by automatically subtracting barometric data from level data collected by any Level TROLL. |
