In-Situ reliability at our lowest price.

The new Level TROLL® 100 is an economical, absolute (non-vented) instrument for monitoring and recording changes in water level, pressure, and temperature. The Level TROLL® 100 is designed to measure these parameters in down hole wells, boreholes, tanks, rivers, streams, lakes, and reservoirs. This instrument provides the accuracy, reliability, and ease of use needed for long or short term water level monitoring. The Level TROLL® 100 body and nose cone are constructed of a durable acetal alloy with a diameter of 1.03 inches (26.2 mm) and a length of 5.5 inches (14 cm) with a ceramic pressure sensor perfect for monitoring in all types of environmental waters. The instrument uses an USB or RS232 communication interface to program and retrieve data with enough memory to record 32,000 readings including date, time, level and temperature. The Level TROLL® 100 is a sealed instrument using a 3.6V lithium battery with a guaranteed life of 5 years or 2,000,000 readings and has the ability to run Linear, Fast Linear or Event testing.

Additionally, the Level TROLL® 100 is operated by Win-Situ® software and a USB or RS232 Docking Station for programming and downloading your sites water level data. An optional external barometer (BaroTROLL® 100) is available for use with the Level TROLL® 100 which gives the user an easy way to integrate barometric pressure compensation using In-Situ’s Baro Merge™ software. The instrument can be deployed using In-Situ’s Polyurethane coated suspension wire in your choice of lengths 50 ft (15m), 150 ft (45m), or 300 ft (90m).

The Level TROLL® 100 system is of primary interest to those who deploy absolute (non-vented) instrumentation for monitoring and recording of short or long term water level, pressure, or temperature changes in either monitoring wells or open surface water. The instrument is deployed with suspension wire with depth ranges of 0 – 30 ft., 0 – 100 ft., or 0 – 250 ft. The Level TROLL® 100 pressure sensor is constructed of ceramic with a typical accuracy of +/- 0.1% Full Scale and a maximum accuracy of +/- 0.3%. Each Level TROLL® 100 is shipped with a factory calibration report at no charge.
