Aquaread LeveLine-Mini CTD SDI-12 and Modbus Level, Conductivity and Temperature Sensor

The Aquaread LeveLine-Mini CTD adds conductivity and salinity to the Mini's water level and temperature output, in a 22 mm titanium sensor only 146 mm long. Like the LeveLine-Mini it has no internal logging or battery, and it connects to SDI-12 or Modbus (RS485) loggers and telemetry, making it a good fit for saltwater intrusion and tracer monitoring on existing networks.

Choose an absolute sensor (non-vented cable plus a barometric reference such as the LeveLine-Baro) or a gauge sensor (vented cable). Cables are listed in the Aquaread Parts & Accessories collection.

Specifications

  • Level ranges: absolute 10, 20, 50 or 100 m; gauge 10, 20 or 50 m; ±0.05% of full scale
