Groundwater Monitoring Equipment
SENSOR

Water quality measuring instrument

Multi-Parameter Sensor
Model : MK-M Series
Multi-depth measuring sensor measures water level, water temperature and EC at once to monitor change of water quality state in each depth.
This instrument can be connected max 8 detachable sensors to one cable in series by each depth.
Each sensor measures water quality data of each depth at once through cable connected underwater connector in each depth.
Especially this equipment is suitable to monitor seawater permeation state in the groundwater
at the coastal and insular area.
