In-Situ Aqua TROLL 200 Data Logger

In-Situ Aqua TROLL 200 Data Logger

Pine Item #54567

The Aqua TROLL 200 Data Logger measures and records water level, pressure, conductivity, and temperature. A unique conductivity cell design allows for a wide, accurate measurement range in a narrow diameter instrument. Titanium construction resists corrosion, ideal for coastal, remediation, and mine water monitoring projects.

Available in pressure ranges up to 1153 ft (351 m) for vented configurations and 1120 ft (341 m) for non-vented configurations. Get easy data access via telemetry or direct-read Rugged Cable (sold separately).
