Aqua TROLL 200 Water Level Recorder

Product Details

The qua TROLL 200 water level recorder measures and records water level, water pressure, electrical conductivity, and temperature. For ventilated structures, the pressure range can reach 1153 feet (351 meters), and for unvented structures, the pressure range can reach 1120 feet (341 meters). Use the Aqua TROLL 100 to measure and record only conductivity and temperature, and can be deployed at a maximum depth of 500psi (1153ft; 351.43m). The unique conductivity cell design can achieve a wide range and high accuracy measurement in a small diameter instrument. Direct readings via telemetry system and HydroVu data service, or via Rugged Cable (sold separately).

Aqua TROLL 200 Water Level Recorder
