The NKE Leveline CTD Water Level, Conductivity, Temperature 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.
The NKE Leveline CTD Water Level, Conductivity, Temperature is a 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.
Take a look at some of the features:
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.
The 4 ring stainless steel sensor of the NKE Leveline CTD Water Level, Conductivity, Temperature 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 NKE Leveline CTD Water Level, Conductivity, Temperature 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 100µS – 99,999µS, 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 NKE Liveline LL-200 GPS Water Level Meter.
