The HI769828-3 is a 4-ring electrode conductivity (EC/TDS/Resistivity/ salinity) sensor for use with the HI769828 probe. The sensor body is constructed of durable polyvinyl chloride (PVC) material and contains AISI 316 stainless steel electrodes that are not subject to polarization or surface coating effects. Each module is color coded for easy installation and integration with the probe.
  • PVC Sensor Body
  • 4 Ring Stainless Steel Electrodes
  • Color Coded Sensor


PVC Body

The PVC sensor body is suitable for a wide range of applications and excels in field measurements due to its durability. The shielding around the electrodes minimizes breakage due to accidental bumping or dropping. The PVC plastic is a high-quality synthetic plastic that is chemically resistant to many harsh chemicals.

4-Ring Stainless Steel Electrodes

A 4-ring electrode design allows for reduced polarization and surface coating effects over an extended linear range of measurement. Stainless steel electrode construction makes for a durable sensor in field conditions.

Color Coded Sensor

Sensors are color coded to match sensor ports on the probe for quick, field-replaceable, screw-type, connection and identification.
