Performance features: 1. Advanced method of determination High sensitive chemiluminescence immunoassay was used. 2. Efficient integrated design Japan precision three-dimensional transmission, low-loss optical fiber transmission, excellent instrument performance and low noise operation. Built-in 25 ℃ constant temperature vibration system to ensure the uniqueness of the detection results. 3. Flexible mode of work Single board multi-item test function, suitable for batch test or emergency random test. 4. Strict quality control Specially treated optical absorption surfaces and optimal reflection systems (patented technology), maximum elimination of inter-hole interference. Automatic range switching, multi-rule quality control to ensure detection accuracy. 5. System self-diagnostic function When the instrument fails, the system automatically diagnoses and displays the detailed fault type. 6. Comprehensive quantitative analysis Built in multiple mathematical models. The calibration curve can also be set by the laboratory. Single point or two-point calibration is used to correct the factory curve to reduce the usage of standard night. 7.Sophisticated data processing Chinese Windows XP system platform, man-machine dialogue software interface. The statistical function is diverse and the report forms are free to output. Convenient hospital intranet, remote diagnosis and maintenance.
