The OTT PLS-C measures water conductivity, level, and temperature in both surface and groundwater applications with a robust ceramic pressure cell and 4-electrode conductivity cell. Its extremely low power consumption makes it ideal for long-term deployment, particularly at solar powered measuring stations for ground-and surface waters.
Surface water, Groundwater
Vented pressure cell and 4-electrode graphite conductivity cell
Water level, Pressure, Conductivity, Temperature
Water level, temperature, and conductivity measurement – for use with external data logger
No
SDI-12 or RS-485 (using SDI-12)
Advantages
Outputs for conductivity include specific conductivity, salinity, and total dissolved solids
The robust ceramic pressure cell offers industry-leading accuracy and does not deform over time like membrane technology, providing long-term measurement stability
Rugged design: Ceramic pressure cell resistant to physical force (4 x burst pressure) and enclosure made of high-quality saltwater resistant steel for use in coastal environments
Vented pressure probe, automatically compensates for changes in barometric pressure
Robust cable with Kevlar core for length stabilization and capillary tube for venting
Built-in microcontroller – compensates for temperature effects and applies correction values for gravitational acceleration or water density
Simple setup and connection to external dataloggers using SDI-12
Examples of Use
Water level, temperature, and conductivity measurement of:
Groundwater wells
Streams, rivers, channels, and canals
Reservoirs, lakes, and wetlands
Ideal for monitoring:
Continuous monitoring networks
Short-term or long-term projects
Salt water intrusion
Aquifer storage and recovery
Estuaries and wetlands
