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.
LEVELINE-CTD WATER LEVEL ,TEMPERATURE, CONDUCTIVITY AND SALINITY LOGGER
The brand new Leveline CTD from Aquaread expands our range of highly accurate water level loggers to now include an all in one level, temperature, conductivity and salinity level logger.
The Leveline CTD is an ideal choice to measure level and conductivity levels in the following applications
Salt water intrusion and soil salination monitoring
Contaminant plume remediation monitoring and studies
Leachate monitoring at landfills, mine, waste disposal storage sites
Agricultural and storm water runoff monitoring
The leveline CTD is manufactured from titanium and is ideal for long term deployment in the harshest of environments. It also has a leading accuracy, 500,000 data point memory and direct SDI12/RS485 output. Absolute or gauge variants are to cover all the usual applications from groundwater to surface water.
Telemetry is also available to add this sensor into a large network of monitoring instruments and can be easily combined with our range of water quality aquaprobes.
LEVELINE-CTD FOR CONDUCTIVITY AND SALINITY MEASUREMENTS
The 4 ring stainless steel sensor of the LeveLine-CTD measures the conductivity of the water sample. From this reading along with temperature, salinity can be calculated automatically. Salinity would normally only be calculated during data analysis using other sensors. This makes the LeveLine-CTD an ideal choice for telemetric deployments, you get all of the readings straight out of the logger with no extra calculation or analysis required.
Calibration of the conductivity sensor can be carried our using any concentration of solution between 100?S – 99,999?S, it is user programmable. Calibration scan be performed with when the LeveLine-CTD is connected to the PC through LeveLink or when connected to the GPS LeveLine meter.
