In-Situ Aqua TROLL 100 Conductivity Logger
The In-Situ Aqua TROLL 100 conductivity logger simultaneously measures and logs temperature and conductivity. It can be used as an autonomous logger or integrated with a remote telemetry system.
- 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
The In-Situ Aqua TROLL 100 conductivity logger instrument simultaneously measures and logs conductivity and temperature. Conductivity measurements can be used to characterize water quality changes relative to a baseline or to estimate the concentration of contaminants. 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 100 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. The instrument is completely sealed to withstand pressures up to 500 PSI. 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.
