Conductivity cells for different applications.

The TetraCon® 4-electrode system sets the standard for professional conductivity measurements. When compared to conventional 2-electrode conductivity cell, the TetraCon® cells offer a high degree of precision, wider measuring range and minimal immersion depth needed for measuring. Additionally, these superior cells eliminate errors caused by polarization effects, and from dirty samples.

TetraCon®

In comparison with conventional measuring cells with 2 electrodes, the TetraCon® conductivity cell offers numerous technical advantages:

• Highest degree of precision and linearity by optimized cell geometry
• Extremely large measuring range with just one cell
• Long-term cell constant stability with high-quality abrasion-resistant graphite electrodes
• With built-in temperature probe
• Smallest immersion depth possible
• No measuring errors even with very dirty electrodes – contact resistance on the electrode surface is automatically compensated
• No measuring errors from cable influences
• No measuring errors from primary or secondary polarization effects
• No measuring errors due to contact with side walls or base of measuring vessels
• Robust, unbreakable epoxy body
