Introduction
       BL-420S Data Acquisition & Analysis System is a third generation Research Concept Data Acquisition & Analysis System developed. It’s with higher performance indexes and much easier to operate than any other similar products in home and abroad markets, for example: editable wave stimulation device, hardware automatic peak-seeking function, which cannot be produced by other internal factories.
Characteristic
      1.  USB2.0 full-speed method. The highest collection rate is 200 KHz.
     2.  Using 16-bit precision A/D switching chip.
     3.  Input channel is isolated with Photoelectricity, more secure and reliable.
     4.  The stimulation intensity reaches 100V and the stimulation wave can be edited arbitrarily.
     5.  There are inner extended interfaces that could extend to standard Twelve-lead Electrocardiograph Input or Blood Impedance Input.

HONGKONG LIHUA ELECTRONIC TECHNOLOGY DEVELOPMENT CO., LIMITED is specialized in the production and sales of research experiments microcirculation， using SDF technology (sidestream darkfield imaging (SDF), sidestream dark field (SDF) imaging ), the observed changes in special parts of the animal and human blood. observe the special parts of the animal or human blood flow changes.
The condition of the blood vessels and blood of experimental animals can provide for the animal experiments, in order to cardiovascular disease in experimental animals blood poisoning、sepsis and failure early noninvasive monitoring and scientific data, and provide scientific data for the human disease.
Product: sublingual microcirculation (lingua microcirculation,tongue microcirculation, cerebral microcirculation, renal microcirculation ,visualize the microcirculation at the bedside and sidestream dark field (SDF) handheld imaging device (Microvascular (blood) image observation instrument) etc.
Its technical characteristics are as follows:
(1) Use SDF technology, can observe animal or person special parts such as the tongue, kidney and other parts of the blood flow changes.
(2)can provide the number of capillaries, vascular caliber and velocity, TVD / PVD, PPV, / MFI of experimental animals of data , and so on .
(3) equipment with convenience, can be carried out directly noninvasive observed in the laboratory experiments bedside characteristics, operation is simple.
