The Hydrolab Conductivity sensor uses four graphite electrodes in an open cell design to provide extremely accurate and reliable data with virtually no maintenance.

• Design based on four graphite electrodes in an open cell design.
• The probe measures the current between 2 electrodes held at a fixed potential; additional electrodes are used to compensate for any fouling of the electrode surfaces.
• Sensor measurements used to derive Salinity, Total Dissolved Solids, and Resistivity.

• Reduces measurement error due to environment – sediment falls to the bottom of the cell, and bubbles rise to the top.
• Measurements are reliable in any condition.
• Easily maintained between deployments by cleaning with a Q-tip or cotton swab.
