...The Standard for Water Level

In-Situ Inc. has been designing and manufacturing world-class environmental monitoring instrumentation for over 25 years. In-Situ understands the need for accurate, reliable assessments, and makes significant investments in Research and Development to ensure that they deliver the latest product and technological innovations in helping you ensure clean, safe groundwater and surface water resources across the globe.

 In-Situ® uses the newest sensor technologies in its LevelTROLL® line of level, pressure and data logging instruments. All LevelTROLL® sensors are designed for use in many applications. Acetal alloy (100), 316 stainless steel (300) and titanium (500, 700) sensors can be placed into all types of environmental waters. For superior corrosion-resistance in brackish or saltwater, choose the acetal alloy or titanium models.

 Building on the successful LevelTROLL® platform, the Aqua TROLL® 200 is the first in a new line of water quality instruments from In-Situ® Inc. The Aqua TROLL® monitors and logs conductivity, level/pressure and temperature in the harshest environments.

In addition to the same high accuracy pressure sensor utilized by the LevelTROLL®, the Aqua TROLL® 200 delivers superior water level accuracy in estuary and coastal environments where salinity values vary due to mixing, rainfall or tides by dynamically compensating level readings for changes in water density due to changes in salinity.

 Flexible communications and powerful data management software are features of In-Situ engineering. The LevelTROLL® 300, 500 and 700 and Aqua TROLL® 200 feature Modbus (RS485), SDI-12 and 4-20mA outputs. Connect each of these units to a SCADA or PLC system without any special adaptors. The Aqua TROLL® 200 is also telemetry ready.

 Whether you are gathering information about your body of water for a few moments, or over a period of years, you can rely upon In-Situ instruments to provide accurate results and reliable operation, even in harsh conditions. Contact Geotech for more information about the many applications and model choices of In-Situ LevelTROLLs and Aqua TROLLs.
