EHVT-50 is a multifunctional fully automatic device designed specifically for animals that integrates blood cell analysis, feces formed element analysis, urine formed element analysis, and immunoassay analysis. The device uses a new methodology to achieve detection through cell image recognition and formed element image recognition, which is closer to the gold standard of microscopy. The pipeline-free design eliminates the tediousness and cost of regular maintenance, making the equipment run more stably.
