Description
TetraCon® 925/C is a 4-pole IDS conductivity measuring cell featuring graphite electrodes, an epoxy shaft and a PEEK head designed for acidic environments. With a cell constant of 0,475 cm⁻¹, this sensor supports a broad range of laboratory conductivity measurements. The electrode is supplied with a 1,5 m fixed cable and waterproof digital plug for direct connection to MultiLine®, MonoLine or inoLab® IDS instruments. Graphite electrodes together with the chemically resistant epoxy shaft and PEEK head provide durability when working with aggressive or acidic samples. Four-electrode measurement principles help minimize polarization effects and maintain accuracy across varying sample matrices. The TetraCon® 925/C from manufacturer WTW - a Xylem brand employs digital IDS technology for interference-free data transmission and simplified handling. Supplied as one piece, the cell integrates readily into modern digital laboratory systems used in research, process monitoring and quality assurance. Its robust construction and defined cell geometry ensure consistent performance in routine and demanding analytical workflows.

Questions about TetraCon® 925/C, 4-electrode-IDS conductivity cell with graphite electrodes, epo
What is this article?
TetraCon® 925/C, 4-electrode-IDS conductivity cell with graphite electrodes, epo is the article on this page. Luminix Health distributes WTW - a Xylem brand for laboratory use. It sits in Stirring shafts, propellers & impellers, inside Stirring, shaking & mixing, in Lab instruments.
A shaft, a propeller or an impeller is the wetted end of an overhead stirrer. The diameter and the pitch decide whether the liquid turns over. The material, stainless steel or PTFE, decides what the liquid may be. The chuck size has to match the stirrer.
Stirring keeps a mixture uniform or helps a solid dissolve. A magnetic stirrer spins a bar inside a closed vessel. An overhead stirrer drives a shaft when the liquid is viscous or the volume is large. A vortex mixer agitates a tube. A shaker moves a whole rack or a plate. The shape of the impeller and the speed decide whether the liquid turns over or merely spins. The vessels being stirred are indexed under ISO laboratory glassware.
