Etymology: < cyto- comb. form + -meter comb. form2, probably after Italian citometro (1879, earliest in discussions of the chromocytometer (see below); compare also German Cytometer (1880 or earlier)). Compare Italian cromo-citometro (G. Bizzozero 1879), French chromocytomètre , German Chromocytometer , and also English chromocytometer (all 1880). Compare earlier haemocytometer n. at haemo- comb. form . Compare also slightly earlier cytometric adj.
