由中国颗粒学会颗粒测试专业委员会和中国计量科学研究院化学研究所主办的第二届全国粒度仪量值比对活动历时1年(2008年5月～2009年5月),于2009年5月26日在北京圆满结束。参加本次比对的粒度仪分为3类:第一类为超微范围(0.1μm以下)粒度仪,包括成都精新公司的JL-1177型,珠海欧美克公司的LS900型,丹东百特公司的BT-2003型等3个型号的激光粒度仪,美国麦奇克公司的NPA150型,
By the China Particle Society of Particle Test Committee and the Chinese Institute of Chemistry Institute of Chemistry hosted the second national particle size measurement value comparison activities lasted 1 year (May 2008 ~ May 2009), in May 2009 On the 26th in Beijing successfully concluded. Participate in the comparison of the particle size analyzer is divided into three categories: The first category for the ultra-micro range (0.1μm below) particle size analyzer, including Chengdu Jing new company JL-1177 type, Zhuhai Omega company LS900 type, Dandong Baxter The company’s BT-2003 type 3 laser particle size analyzer, the United States McChick NPA150 type,
