PRODUCT DETAIL
In the field of powder particle size testing, magnetic materials, powder, cement, lithium carbonate, chemical and other kinds of powder that should not be tested by water ( wet process ) are usually measured by laser particle size analyzer ( dry process). The laser particle size analyzer ( dry process ) , with a unique device to realize instantaneous dispersion, instantaneous measurement, so as to guarantee the instrument repeatability and stability. The instrument is quick in test, fully automatic and stable in result and it is the first choice for various industries to test the distribution of dry powder granularity.

APPLICATIONS
Particle size test of solid powder in various fields such as magnetic materials, medicine powder, cement, powder coating, chemical engineering, food, pesticide, electronics, papermaking, metallurgy, ceramics, building materials, grinding material, calcium carbonate, talcum powder, kaolin, alumina, rare earth, catalyst, foaming agent, padding, graphite, pigment etc.

FEATURES
1）The instrument has three parts: mainframe, auxiliary engine ( it contains filter separation purifier, dust extraction system, dust storage tank), oil free silent air compressor. Intergrated optical-electromechanical whole sealing structure, effectively prevent dust pollution, strong anti-interference ability, system automatic recovery pf powder.
2）The unique design of 92 photoelectric detector arrays makes the measurement precision and resolution ratio extremely high. Directly test the powder without adding dispersant and solvent.
3）easy and simple to handle，just click the “automatic test” button. According to the suggestion, put the sample into ample injection parts and complete the whole measurement process (it contains measurement parameter selection, centering, background measurement, concentration adjustment, signal sampling, data analysis, results’ storage, query, compare, edit etc.) automatically under the control of computer.
