The Aqua TROLL^® 100 Instrument measures and logs conductivity and temperature. The cell design allows for a wide measurement range in a narrow diameter instrument (0.72 in; 1.83 cm).

Rugged Design

• Titanium housing safeguards against corrosion.
• Sealed to withstand pressures of up to 500 psi.
  
  

Extended Deployments

• Typical battery life is 5 years or 200,000 readings. External batteries, solar power, or external 8-36 VDC options are available.
• TROLL^® Shield Antifouling Guard reduces fouling and increases deployment times.
  
  

Accurate Results

• Instruments are factory calibrated and validated with NIST^®-traceable standards.
• TROLL Shield Antifouling Guard improves instrument accuracy and performance.
  
  

Flexible Communications

• SCADA and telemetry-ready units include built-in Modbus/RS485, SDI-12, and 4-20 mA output.
• Easily connects to a RuggedReader^® Handheld PC, laptop, TROLL^® Link Telemetry System, or Con TROLL^® PRO System.
  
  

Simplified Setup and Data Aquisition

• Win-Situ^® Software simplifies setup and automates site management.
• Multiple logging modes available.
