Technical requirements
A)Testing range:0-140 mm/h (results of Wechsler)
B) Testing relevance:Wechsler results of the linear correlation coefficient r≥0.98
C) Testing repetitive : CV < 3%
Main function
A)Sample Adding Method : Insert the sample any time; detect the sample any time;
B)The output of the results:Display and print samples' No. (serial number), Wechsler results and the whole process of erythrocyte sedimentation rate curve, detection time and temperature; when the instrument detection time is 60 minutes, it can automatically calculate, display and print Katz index
C)Instrument can choose the ambient temperature compensation. When selecting the function, when the room temperature is 18 ºC -30 ºC, it amends to 18 ºC according to the blood sedimentation calibration test results. (It can be selected in accordance with laboratory, the default of equipment is no compensated)
D)Equipment can be stored not less than 150 samples of the test results, including the sample number (serial number), erythrocyte sedimentation rate values and the dynamic curve
E)There are power-off protection function, when a sudden power failure, automatic detection has been completed the tested results
F)Built-in thermal printer preparation equipment, it has automatic, manual printing options
G)Operation interface: Film keyboard operation
H) Communication Interface: RS-232 serial interface
