Infrared optical detection technology                                 
Automatically scanning blood cells and location of the plasma interface from time to        
time with accurate positioning                        
Internal thermal printer, ESR curve display and print-out
Automatically amending the ESR results under the detecting temperature (15°C~32°C) to the
ESR values at 18°C, closely related with Westergren results             
The results are not interfered by pharmacological samples such as jaundice,
hemolysis or chyle
