The LeveLine-Mini-CTD is a titanium water level, temperature, conductivity and salinity measuring sensor that has been specifically designed to bring conductivity and salinity measurements to your telemetry deployments.

The LeveLine-Mini-CTD adds conductivity and salinity measurements to the small SDI-12 ready sensor. Like the standard LeveLine-Mini, the CTD version is housed in a titanium body making it suitable for deployment in both fresh and salt waters. It also features the same titanium connector as the larger LeveLine loggers. The connector allows the unit to be connected to your PC or to the GPS LeveLine Meter to calibrate the conductivity sensor.

The LeveLine-Mini-CTD is available in both absolute and gauge versions. If your chosen data logger / telemetry device includes a built-in air pressure sensor, we recommend the absolute version as the logging device can utilise the air pressure reading for compensation. If an air pressure sensor is unavailable then the gauge version is best suited for telemetric logging.

Gauge sensors require vented cables and desiccant cartridges to remove any moisture from the vent to prevent blocking and inaccurate compensation.
