Introduction: The instrument adopts the exchange method determination of Zeta potential quality. So-called quality type exchange Zeta potential meter is actually based on electrophoresis rate determination of Zeta potential, but not watching the movement of particles velocity individually, but into the speed quality, the directional movement of particles collected on the electrode, according to the weight calculation of Zeta potential of electrode. Collect samples of particle electrode is free of loading and unloading the bottom of the pool, its weight is by weighing the weight of the sample pool experiments before and after the experiment is obtained. Because of the electrode in the collection of particles of opposite electric charge at the same time, to discharge the liquid medium with volume, obtained by weight is actually is deposited on the electrode particle weight minus the with the weight of the liquid volume. Similar instruments in the U.S. are weighing method, but it is difficult to accurately weighing, the instrument on weight gain is depending on the light transmittance of different concentrations of liquid, the first to get the light transmittance, to obtain the corresponding liquid concentration, according to the change of the concentration, weight gain is obtained. Therefore, compared with other similar instruments both at home and abroad, the instrument has remarkable superiority. Features 1. The sample of the equivalent weight of Zeta potential pool, there is no typical problems. 2. The measurement process, constantly rotating sample pool, avoids the problem of large particles precipitate. 3. Sample pool weight includes the total big particles and small particles as a result, does not exist the problem of small particles observed. 4. With relatively high concentrations of liquid sample determination, close to the oil, the actual use of papermaking industry. Technical Parameter Power consumption: < 20 w Applicable environment: shockproof platform Temperature: 5 ℃to 35 ℃ Accuracy: system error is within 5% Applicable to 0.1-100 um, concentration of 1% - 50% of the decentralized system PH range: normally used in 2.0 ~ 12.0
