The LeveLine CTD records highly accurate water level, temperature, conductivity and salinity measurements in a wide range of groundwater and surface water applications. Housed inside the sealed body is a ceramic level sensor, temperature sensor, 10-year lithium battery and a versatile datalogger with capacity for 500,000 data points.
The LeveLine CTD Absolute uses a piezoresistive ceramic pressure sensor to provide excellent durability and long-term stability whilst delivering an impressive accuracy of 0.05% FS. A variety of level ranges are available and all of them are temperature compensated across a scale of -20 to 80 deg. C. The conductivity sensor is adapted from our long established Aquaprobe range and records
measurements of conductivity and salinity with an impressive 0-200,000 us/cm range or 0-70 PSU for Salinity
