Surface charge detection of solid matter, fibers and particles.
The MütekTM SZP-10 System Zeta Potential measures the surface charge of solid materials suspended in water. The resulting zeta potential is based on a streaming potential measurement after an automatic plug formation of the sample material. The device is widely used in the paper industry and in pigment applications as well as for coating evaluations.
The SZP-10 is a stand-alone unit. Data transfer to USB stick or directly into BTG Software is possible via a USB interface.
The instrument is designed for indoor use at an ambient temperature of 10 °C to 40 °C (50 °F – 104 °F). It must be placed on a flat and stable surface at least 20 cm (8 inch) away from walls and should be protected against water. It must not be used in explosion prone rooms. It is rated for voltages of 100 - 240 VAC at 50 Hz / 60 Hz.
Generally a streaming potential can be measured for particles larger than the openings (308 μm or 40 μm) of the screen electrode used. To measure samples containing particles smaller than 40 μm, a suitable paper filter has to be inserted.
