The Online Conductivity/salinity /TDS/TEMP Sensor Features A Four-electrode Replaceable Probe Design
1.product overview
KNF-102HPRO conductivity and salinity sensor is a newly designed sensor, which has been upgraded on the basis of many field application experiences, and is simple and convenient to use. KNF-102HPRO conductivity and salinity sensing design can be used for pipeline installation (optional accessories: Y-type 3-way with end face seal) or submerged installation. When it is used in pipeline installation, it can bear the pipeline pressure of 6bar at the highest, and the submerged installation can ensure the normal use of 50m water depth. The conductivity adopts 4-electrode working mode, and the electrode material is graphite, which can effectively reduce the damage of polarization effect to the sensor. The salinity sensor adopts international salinity standard and can be used in mariculture and marine salinity monitoring.
