LA-950 激光粒度仪的重复性研究

Study on LA-950 gage-to-gage variation was performed with 4 different
samples on 2 random selected units of LA-950 (S/N EVD and HOO). The
samples were Whitehouse Standard PS-202 (3-30m), Duke BCR-66 (1-
10m), a customers samples A (median 0.7) and B (median 1.2).
Variations between samp领-to-samp领, instrument-to-instrument are all
below 10%. 新一代的高性能激光粒度分析仪
