Multiple PCR quantitative inspecting device

A quantitative detector of multiple PCR is featured as reflecting variation of DNA amplification product amount on template by variation of fluorescence energy released from fluorescent dye in DNA amplification course under light and under temperature environment of heat circulator, presenting variables of fluorescent signal and amplification product to be direct ratio, collecting fluorescence by photoelectric component, comparing and analyzing fluorescence intensity of object to be detected with fluorescence intensity of reference material with application software packet for achieving quantitative analysis of original template amount.
