The Zeta Potential Analyzer ZPA 20 utilises the patented bidirectional oscillating streaming potential method for the measurement of zeta potential of various materials with a high degree of accuracy and precision. Samples with plate shaped geometries, fibres and powders can be easily prepared and measured as well. High precision measuring probes for voltage, current, conductivity, pH value, pressure and temperature are also possible with the system.
