With 3-parameter sensor, robust ceramic pressure cell and 4-electrode conductivity cell
It measures water conductivity, level and temperature in both surface and ground water applications.
Extremely low power consumption, especially for ground and surface waters
ideal for long-term use in solar powered stations.
The sensor is capable of being used under water for long years.
The robust ceramic pressure cell offers industrial precision and long-term
has membrane technology providing measurement stability and does not deform over time.
Robust design: Physical strength resistant ceramic pressure cell (4 x burst pressure)
and for use in coastal environments; Housing made of high quality salt water resistant steel
The ventilated pressure probe automatically compensates for changes in barometric pressure.
Built-in microcontroller - compensates for temperature effects and gravity acceleration
or apply correction values for water density.
Usage areas :
Groundwater
Streams and Rivers
Reservoirs, Lakes and Wetlands
