名称:Zeta电位仪

品牌:CAD

产地:法国

型号: ZetaCAD®

An electrolyte is forced to pass through a capillary or porous plug by a pressure gradient. The excess charges around the particles or wall are carried along by the liquid. Their accumulation downstream causes the build-up of an electric field which drives an electric current back (by ionic conduction) through the liquid, against the direction of the liquid flow. A steady state is quickly established and the measured potential across the capillary is called the streaming potential.

CAD Instruments offers wide range of services to help you take advantage of this new measurement device. The ZetaCAD can be used for major industrial and academic applications including:


• Ceramics                               • Water treatment            • Polymers
• Fibre and Textile                  • Pulp & Paper                 • Geology
• Membranes




Parameters Measured
• Streaming Potential
• Streaming current (optional)
• Plug resistance
