Standard conductivity cell probe TetraCon^® 325:
4-pole cell with integral temperature sensor. Measuring range: 1µS/cm to 2S/cm.

Special conductivity cell probe TetraCon^® 325/C:
As TetraCon^® 325, 4-pole cell with integral temperature sensor, but with sensor head made of chemically resistant PEEK. Measuring range: 1µS/cm to 2S/cm

With integrated reference electrode. Easy cleaning of the diaphragm between measurements with Click & Clear™ (except Na electrode): by pressing the electrode head, the electrolyte solution flows through the diaphragm. The electrolyte can be easily emptied and refilled. Optimum contact between sample and electrolyte solution is always guaranteed.

Scope of supply: Sensor with permanently connected 1.2 m cable with BNC connection, 60 ml reference electrolyte, operating instructions

Scope of supply Na-electrode: Sensor with S7 plug head, diaphragm made of glass with higher sensitivity to sodium, 25 ml reference electrolyte, operating instructions

Combined ISE and GSE electrodes.
