In-Situ Aqua TROLL 200 Water Level & Conductivity Logger

The In-Situ Aqua TROLL 200 instrument simultaneously measures and logs water level, conductivity and temperature.

Features

  • 4-electrode conductivity cell is less subject to fouling and resists electrical field effects from pumps and well casings
  • Internal batteries guaranteed to last for 5 years when reading every 15 minutes
  • Durable titanium housing resists fouling and safeguards against corrosion, even in the harshest conditions

Details

The In-Situ Aqua TROLL 200 instrument simultaneously measures and logs water level, conductivity and temperature. Dynamic density compensation delivers superior water level accuracy in estuarine and coastal environments where salinity values may vary due to mixing, rainfall, or tides. The instrument dynamically compensates level readings for changes in water density due to changes in salinity. Instruments are factory-calibrated and validated with NIST-traceable standards.

When used as an autonomous logger, standard logging modes include linear, linear average, and event testing with logging rates as fast as 1 sec. Internal batteries are guaranteed to last for five years at a 15 minute sampling interval. For remote data telemetry applications, the Aqua TROLL 200 also has built-in Modbus RS485, SDI-12, and 4-20mA output communications.

The durable titanium housing resists fouling and safeguards against corrosion, even in the harshest of conditions. When used in coastal environments and high-fouling sites, the optional TROLL Shield antifouling system combats biofouling of the Aqua TROLL instrument and its conductivity cell. Reduced sensor fouling extends instrument deployment by up to 6 weeks and improves instrument accuracy and performance. The TROLL Shield antifouling system includes a copper nose cone and coiled copper guard.
