Since the blood analyzer has launched more than one hundred years, through technical innovation, blood analyzer detection technology has had the significant changes, also on the market at present common blood analyzer used by the detection principle includes the following two kinds: Kurt principle and photoelectric colorimetry. Plant below small make up to you in detail the common common blood analyzer detection principle:

Blood cell analyzer is done using holes can exchange equipment. The medical equipment is the key component of a count by the impedance method, impedance method to test the sensors.

Under the effect of negative pressure, the cell through tiny holes in a flash lined volume of electrolyte, the equivalent resistance of the electric solution liquid in a flash. The larger the resistance under the effect of constant current source leads to a proportional increase of electricity, etc. Cells out of the holes, the equivalent resistance, resistance of liquid and recover normal, until the next cell in holes, such cells have through holes, the electrodes at both ends in a series of voltage pulses. Pulse number and the number of cells through holes properly; The ups and downs pulse is proportional to the cell volume. Will these pulses by plastic, expanding, accounting, storage and disposal, got the cell classification and counting of the raw data. This is Kurt principle.

Hemoglobin photoelectric colorimetry. Selects the wavelength of 540 nm semiconductor cold light source, the absorption peak of 540 nm light electric equipment analog photoelectric sensors. The white blood cell count in the pool of hemoglobin concentration change after the change of the bridge circuit is converted into voltage signal, and then measured the concentration of hemoglobin values.
