The ELT-8 laser haematological cell counter is a fully mechanized instrument, which measures the forward scatter of light from a helium-neon laser caused by suspended particles. The apparatus has high practicability, and uses a very small sample volume of 100 microliters. The operational procedure is simple and quickly learned. In the second year of operation, down time for the instrument was, on average, 8 hours/month. Depending on the parameter, the precision of the measurements are between 0.5 and 4% in series, and 1-9% day-to-day...
