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 datalogger / 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.

LeveLine-Mini as part of the LeveLine-EWS  Package


The LeveLine-Mini is the level sensor used in the Early Warning System to alert for rising water levels. the clever AquaTelemetry system features a built in pressure sensor meaning the level data recorded by the system is fully compensated for changes in barometric air pressure.

 Connect to any SDI-12 datalogger or telemetry device

The LeveLine-Mini has SDI-12 and Modbus (RS485) outputs as standard meaning you can connect this sensor to any established monitoring platform that accepts these protocols.
